    I spent days and days inside the STAR control room in grad school, often during the 12:30am-7:30am graveyard shift. We needed to run 24/7 for efficiency reasons during the experimental season. Getting superconductors down to temp is costly, so once you get it there, it is go time all the time.

    You had to stay on top of all the detectors and triggers, since every minute of beam time cost around $1k. You often sat around doing little, probably working on other research, and then would need to drop everything to reboot a detector so we could get back to collecting data.

    RHIC is dead. Long live eRHIC.

      Thanks for contributing to research.

      What was the “experimental season”? Why was there an experimental season vs. running RHIC all year?

        Maintainance and upgrades. These big shared facilities they are shutdown regularly and researchers work flat out while they're up.

    This is in preparation for starting construction work on the Electron-Ion-Collider (EIC) which will use the same tunnel and experiment locations.

    • gnufx 11 hours ago

      As I recall, RHIC itself replaced some cancelled project. I remember the tunnel being at least partly there in the mid-80s, with a plan to trundle ions from the tandem lab through a crazy long beamline across the site and stop nuclear structure research there as a result.

        ISABELLE, which was a cancelled proton-proton collider. Major delays with its magnet design meant that it was overtaken by existing programs at CERN and Fermilab. RHIC reused its hall.

    My father worked on PHOENIX for over a decade and I got to watch all the equipment being assembled as a teen, unforgettable to have spent time so close to "big science". During budget cuts Jim Simons paid to keep the accelerator running.

    How time passes! I remember touring the RHIC tunnels back in 1999 when it was being made.

    sPHENIX uses software that we’ve worked on at CERN to do some of their reconstruction!

    I worked at BNL during college days through the SULI program! Some of my peers from college is working there full time now too. I got to work on some really cool stuff but unfortunately a lot of the tenured researcher I knew have seem to left. I heard a lot of researchers left during Trump’s first term.

    as a layperson, it seems the whole collider stuff has not been a very fruitful scientific direction so far (has there been any discovery made with the help of a collider that found its way into an industrial product?)

    maybe we are trying to 'jump' the tech tree too much - perhaps the first step was to create a much smarter entity than ourselves, and then letting it have a look at the collider data.

      > has there been any discovery made with the help of a collider that found its way into an industrial product?

      Yes. SLAC has an excellent public-lecture series that touches on industrial uses of particle colliders [1].

      If you want a concrete example, "four basic technologies have been developed to generate EUV light sources:" (1) synchrotron radiation, (2) discharge-produced plasma, (3) free-elecron lasers (FELs) and (4) laser-produced plasma [2]. Synchrotrons are circular colliders. FELs came out of linear colliders [3]. (China has them too [4].)

      We have modern semiconductors because we built colliders.

        In the context of the article "collider" means intersecting particle beams, like in RHIC and LHC, which obviously involves rather low probability interactions, as opposed to accelerators which slam a beam into a dense target (like the SLAC accelerator). In a synchrotron light source you want the beam to circulate and specifically not collide with anything; they were developed from particle physics accelerators, of course.

    • mgibbs63 10 hours ago

      I think there's a strong argument that the most useful product from collider science is the synchrotron light source. Researchers using collider rings realized that the x-ray synchrotron light these rings emit (an inconvenience to collider physics people) was a fantastic tool for structural biology and materials science. Eventually, they built dedicated electron storage rings that don't do collisions at all - the main goal is producing bright X-ray beams.

      Synchrotron light sources have had wide-ranging, concrete impacts on "industrial products" that you probably use every day via studies in: - Drug discovery (Tamiflu and Paxlovid are good examples) - Battery technology (X-ray studies of how/why batteries degrade over time has lead to better designs) - EUV photolithography techniques - Giant Magetoresistance (Important for high capacity spinning-disk hard drives)

      Particle physicists working on collider experiments were among the first people that needed to deal with large quantities of digitally stored data. As a result, advances in the particle and nuclear physics have fed advances in computing, and vice versa [0]. The World Wide Web was invented at CERN, the largest particle physics and accelerator laboratory in the world [1]. Another example more relevant to this post is when a few physicists developed a CouchDB-based solution to handle the large amounts of data generated by their RHIC and CERN experiments. They spun that out into Cloudant, which was one of the pioneers for DBaaS [2].

      The web would be one of the more well known technologies to come out of running collider experiments. More directly a whole lot of medical imaging including PET is only possible because of either isotopes manufactured through colliders or sensors developed in colliders.

    • magicalhippo 10 hours ago

      > has there been any discovery made with the help of a collider that found its way into an industrial product?

      Accelerators and colliders have had a profound impact on medical sciences. Nuclear isotopes used for nuclear medicine[1] is often produced by cyclotrons[2], the accelerator component of circular colliders. The detectors[3] used in things like PET scanners are based on detectors used in collision experiments[4]. Using protons to treat cancer was an idea that came directly from work on cyclotrons[5]. Using the tools developed to simulate how the collision fallout interact with the detectors at LHC[6] has been incorporated into radiotherapy to more accurately compute required doses[7][8].

      > perhaps the first step was to create a much smarter entity than ourselves, and then letting it have a look at the collider data

      We are actually data starved, we have lots of good ideas but no way to test them.

      Tevatron’s construction program built up a lot of industrial capacity for superconducting magnets. This was by design, in the hopes that it would drive induced demand for them. One of the first beneficiaries were MRI machines, which became a lot more affordable to produce.

      The DOE hoped to repeat that success in the 1990s with the much larger SSC, but it was cancelled.

    • gnufx 11 hours ago

      Since when were industrial products the purpose? Why do you think my colleagues can't analyse LHC data and discover the Higgs particle? The article says RHIC was a considerable scientific success.

      Colliders have been the source of almost everything we know about the fundamental nature of reality. That makes them a fruitful scientific direction.

      • mmooss 9 hours ago

        Very much yes: Knowledge is valuable itself. We're discovering the secrets of the universe.

        The owners of capital have created an amazing, self-serving ideology in the US (and elsehwere): If something doesn't help them make money, it's worthless. People seem to think that's part of the US - in the Declaration of Independence and Constitution.

        Even more amazing is that I hear scholars in non-profitable fields parrot those ideas. I think capitalism - and especially free markets - work well in many ways, but it's a means to an end, not a religion. Capitalism serves us, not vice-versa.

    • Keyframe 11 hours ago

      this particular collider or particle accelerators in general? Cyclotrons are rather useful, for example.

    • pfdietz 11 hours ago

      Look at it this way: they are investigating phenomena that require a collider-sized object to see. So unless your application involves a collider sized object, it won't use any effect they discover.

      The problem is that fundamental physics has moved too far beyond the scales where we operate.

      • tehnub 9 hours ago

        I don't think that argument holds up. See quantum mechanics.

        • pfdietz 9 hours ago

          Quantum mechanics is demonstrable on a lab bench (or smaller), so your counterargument is completely wrong.

          Any useful consequence of a physical effect is, in effect, an experiment that could test that effect. So if the smallest test is with a machine the size of a small country, no device using the effect can be smaller.

          • tehnub 7 hours ago

            They’re using big things to do experiments. Maybe they discover some new physical effect. How do you know that that effect couldn’t be demonstrated in some smaller scale experiment after it’s understood better?

            • pfdietz 3 hours ago

              Can you tell me of an example where that has happened? I can't think of any.

      • mmooss 9 hours ago

        You're in an IT forum and can't imagine implementations of both the smallest and largest scales? ICs are built at nanoscale and have to deal with quantum effects. PNT systems are so large that they have to deal with the speed of light and relativistic effects.

        Many things humanity builds are on the scale of colliders.

        > The problem is that fundamental physics

        I didn't know there was a problem. It seems like one of humanity's greatest successes.

        • pfdietz 7 hours ago

          You are mistating my argument. An honest reading, where you try to read what I wrote in the way that makes the most sense, would have concluded I was talking about large scale, not small scale.

      I don't think you understand how collider data is analyzed

      I hate to be harsh but this mentality is part of the decline of this country

      (that is so evident with loss of manufacturing, open and free science and tech robber barons oligarchs that have taken over our national discourse)

      Brookhaven was instrumental to Nobel winning discoveries and Stony Brook was a great science minded university

      I’m not opposed to investing in AI but its not a zero sum game and we are not a country of data centers alone

      • davrosthedalek 5 hours ago

        Why past tense? BNL will host the EIC, and SBU is going full steam.

      • Insanity 11 hours ago

        Nit: saying “this country” without context on where the parent poster is from or where you are from is kinda useless.

        From context, you probably mean USA. And I’d agree, however the US was always more technology minded than scientifically minded, and the parent poster lines up with that centuries old ideology. So I don’t think this is per se a new thing.

      • mindslight 3 hours ago

        FYI the lab isn't shutting down. Glad you appreciate it's achievements though!

      • pfdietz 11 hours ago

        At some point physics entitlement has to end -- why not here? We can't just keep scaling up the size and cost of fundamental physics experiments. Eventually the cost becomes so large that platitudinous arguments for them don't work.

        • mmooss 9 hours ago

          How can you look at current and recent US science and call it 'entitlement'? Have there been larger cuts anywhere in modern history?

          • pfdietz 9 hours ago

            If you think you are entitled to any amount larger than zero, you are showing entitlement.

            • MSFT_Edging 9 hours ago

              It's not an entitlement if you're paying into the tax base.

              I'm somehow entitled to others receiving corporate bailouts, entitled to massive military waste spending, and entitled to seeing the "victims" of Havana Syndrome receiving free healthcare for life.

              Yet I am not entitled to this money going towards research for the greater good of humanity?

        • Izikiel43 10 hours ago

          It's not a question of "can", it's a question of "should". No one knows what discoveries can happen and what the spillover from them could be in the future. In essence, it's a bet, a moonshot.

        • micromacrofoot 10 hours ago

          We absolutely can, and I reckon we will... this is like a fraction of a percent of science funding which is a fraction of a percent of GDP, we spend more on maintaining warheads we can't use

          10% of the US military budget for one year could build a 100km collider, RHIC is 4km

          • pfdietz 10 hours ago

            What a nonsense argument. Spending like this has to be justified on its own merits, not because there is some other bad spending. The argument you are trying to make would justify spending on almost anything.

            • micromacrofoot 10 hours ago

              The point is that there's so much bad spending that by comparison this is practically nothing to shake a stick at, and it produces actual science.

              • pfdietz 10 hours ago

                Repeating a bad argument doesn't transmute it into a good argument. I already explained why your argument is invalid. Please reconsider your dogmatic and irrational support for this kind of spending.

                • SiempreViernes 9 hours ago

                  No, you just asserted that you think existing arguments are invalid, then accused a person who disregarded your assertion of being "dogmatic".
