Tevatron Has Come To the End of Its Run 115

Med-trump writes "The U.S. government's Chicago-area Fermilab has been at the forefront of high-energy physics. That's in large part thanks to the Tevatron, the machine that first reached the energies needed to discover the last quark in the Standard Model. But the Tevatron has come to the end of its run; at 2pm on Friday, it will be shut down for the last time."

      not all of Fermilab is shutting down, just the Tevatron - they can still make a neutrino beam. Just like at CERN, the neutrinos aren't generated by the LHC.

    • No, they had already captured the data, they were looking at interpreting it and checking delays to confirm the CERN results - no new data was to be captured.

      And lets face it, CERNs experiment was not the first to track neutrinos, there is plenty of neutrino tracking data sets out there - they just need to be checked with this in mind (remember, if you aren't looking for something, the chances of you finding it when it exists is smaller than when you are actually looking for it - an unexpected discovery is

        They will be collecting new data with an upgraded MINOS [] experiment.

        Just looking at the old data will prove nothing from the old MINOS experiment because it suggests that CERN did it right with the OPERA experiment. The problem before is the margin of error on the MINOS test is far too high causing the measured speed to be faster then the speed of light with a margin of error overlapping the speed of light. They need to do a slight upgrade [] and redo the tests to get the Margin of Error down.

    I'm wondering what's going to become of the physicists that work at Fermilab. I know one of them from my college days. He's worked there since graduating in the late '70s, one of the few physics majors I knew that actually found employment doing work in physics. (Many others seemed to go into software development.)

      The lab isn't going anywhere. While a few groups are justifiably concerned about their jobs, the overall mood around the lab is optimism. New projects are underway, accelerator research is ongoing, and proposals for new experiments are always in the works.

      There's plenty of work left to be done. The real concern going forward is keeping the government willing to spend money on it.

      I for one am looking forward to the shutdown. The Tevatron was originally due to be turned off a year or two ago, but that was delayed due to difficulties at CERN. It has caused other Fermilab experiments to be delayed. Particularly in the area of neutrino physics.

      No, we're not replacing it. We have made the decision as a society not to compete in accelerators for high-energy physics after we canceled the superconducting supercollider.

      We still have good accelerator facilities for light sources, and there is work to build an accelerator at Fermilab with a high-intensity beam. There is also a proposal for a very powerful light source working it's way through the DOE.

          I think the end of "physics is American" was at least 20 years ago. Most American physicists working on foreign-led collaborations do so from American institutions... as far as I know very few Americans are working in foreign countries.

          I do understand the sentiment, though. Over the last 10 years federal funding of high-energy physics has been essential flat... meaning it has been declining in real terms. A shame.

              Defense costs are small compared to government transfers of money to the old and poor (which are more than 3x defense), and "science" budgets are quite tiny by comparison to either.

                  This is completely false, aside from government pensions (to some small %). Social Security is in no way a savings plan, it's a direct transfer of money. Medicare (the largest single expense) doesn't even look like a savings plan. That's just a bizarre claim to make.

                  . The proportions are obvious when you're honest: we waste most of our money on military/intel. If we spent $300B instead of $1500B, we'd have a surplus (the deficit is $1.17T).

                  Simply not true. Social Security, Medicare, and Medicaid (just about 50% of Medicaid payments now go to the elderly) are now, and always have been, pay-as-you-go programs.

                      No, SS does not have treasury bonds in the usual sense. It only has a record-keeping entry of no economic value (the "special bonds" it holds can't be sold).

                      Many people are confused by this. It's just as ig you had borrowed all of the money from your 401K. You still have an asset in your 401K at that point (the loan to your self), and there's even interest associated with it, but it has no economic value - because you can only take another dollar out if you yourself put that dollar in.

                    • Yes, there's $2.5T in the trust fund -- about five years worth of benefit payments at current rates. The fund is tapped only when current income is insufficient to pay benefits -- tapped for relatively small amounts the last couple of years due to substantial drop-offs in revenue caused by higher unemployment and the payroll-tax holiday. I agree with you that SS is solvent, and can be solvent forever with small adjustments, but it's still very much a pay-as-you-go system, not a savings system.

                      That is not as if you borrowed the money from your 401K. The loan (from SS to Treasury) is not to "itself", because without that loan the Treasury wouldn't have that money. Treasury and SS are different, since Treasury doesn't carry any savings, and simply because they are independent of e

                      There's effectively only one pool of money now. SS can'r pay anyone, can't send a single check, without funds from taxes or borrowing. Why is that hard to understand? The SS trust can't sell its "bonds" - the only way it can spend a dime is if that dime comes into the federal government through the usual channels.

                      And treasury debt stopped being "really low risk" this summer. It's now "relatively low risk", which is a different thing entirely (other sovereign debt sucks more).

      Seriously. You cannot compete and win in everything. You choose your specialty and excel in that. Then you spin that as the most important thing in the world so you can feed your overly nationalistic prides. That's what it looks like to the rest of the world. But even then you sometimes you have to make strategic changes to your areas of focus.

You cannot be #1 in everything. You are not that great and that much above everybody else, and that kind of arrogance only serves to annoy the rest of the civilized world.
