Giant Synchrotron to be Constructed in UK 20
juntunen writes "According to the BBC, construction will start this week on Diamond: a £500 million synchrotron in Oxfordshire at the Rutherford Appleton Laboratory. These facilities are crucial to a deep understanding of structure in matter. With all the new emphasis on biotechnology, demand will certainly be high. Diamond has its own homepage, and the Accelerator Physics Group has publicly available tech notes."

This new acceleratos will only reach about 3.5GeV. Much less than FermiLab's TeV accelerator, so its mail goal is not to discover new sub-atomic particles (as those energies have been studied before) but to have biological applications.

The SSC is crap. The (Large Hadron Collider) LHC being built at CERN reaches higher energies at a fraction of the cost of the SSC. I think RHIC at Brookhaven gets pretty close to SSC energies. Although, applying the technology being used for LHC to a tunnel the size of the one SSC was supposed to use would reach even higher energies.
That suggests an idea. Maybe the tunnel and detector caverns should be approved and built first, then decide what to put in them later.

The LHC reaches a peak energy of 14 TeV while I believe the SSC would have reached 20 TeV. Part of what made the LHC better was that it was built in existing tunnels at CERN, which saved a lot of money.
They are already looking into the creation of a Very Large Hadron Collider with possible energies as high as 100 TeV.

2. The French promised to help fund it. And then pulled out of it. When? This article is lacking in a little depth and background, here... does anyone know more about this?
3. 'understanding the proteins of genes' (paraphrase)??? let me get this straight... you're going to batter a gene with electrons, and see if the X-Men really were just a comic book concept? Or are we going to try to understand basic matter, which should take, oh, say, 19 years 364 days and twelve hours, and then *hurrah* just before the building collapses, we suddenly understand the complete human genome!!! Too bad our proof is buried under the rubble... This article ties together every modern theme, in a facility shaped remarkably like a hubcab...

I don't quite get the "20 years" thing either. The Advanced Light Source [lbl.gov] (ALS) at Berkeley was built in 1942, or at least the original building was. It has naturally gone through a number of upgrades, the last being a totally new synchrotron built in 1987-93?. I don't know about wear and tear on the facility but we've found that as far as macromolecular crystallography (usually meaning proteins) goes, xray intensity is no longer an issue. A complete data set collected at the Advanced Photon Source [anl.gov] at Argonne Nat'l Labs took me less than an hour. That's just 1 second exposures to xrays as opposed to up to an hour or more on our lab's xray source. The big change occuring at synchrotrons for macromolecular crystallography is automation--it takes more time for a newbie to get trained and get set up for their first collection than to actually collect their data, but robotics for this kind of thing are relatively new--also data processing and structure determination is still very time consuming. Structural genomics (basically have structures of all the proteins in an organism determined) is also taking off and automation is a Very Big Thing for them as they screen 100,000's of protein crystals--Syrrx [syrrx.com] is probably the most advanced at this so far. Of course the problem with structural genomics is that you generate 100's of structures that lay around uniterpreted--a process that still requires a human touch. Anyway, hope that's some help.

The reasons for siting at Daresbury seemed to be well thought out and sensible - see the campaign website [freewire.co.uk] for more information.
The government has decided to site it in the expensive South of England, putting the existing synchroton research team at Daresbury in jeopardy and virtually guaranteeing a dispersal of talent.

It's not as big as Diamond, but it's not like they are building the Diamond accelerator out of the blue out in the middle of nowhere with no support infrastructure in place. They are building it after some consideration of the infrastructure already at RAL, which just so HAPPENS to be out in the middle of nowhere. ;-)
Wonderful country however, I need to go back for more beer. ;-)

Originally the site was created to extend particle physics in the North of England (to include a collaboration of the "northern universities": Liverpool, Manchester, Leeds, Hull. A particle physics 5GeV electron synchrotron called NINA was built there in the early to mid 1970s and did some useful work.
It also attracted a new group of condensed matter physicists (surface scientists too) who used the synchrotron radiation emitted to do [dl.ac.uk] spectroscopy and diffraction of various sorts (photelectron spectrosocopy in the extreme UV and soft X-ray where the SR sources are particularly bright compared to other sources). They set up the SRF [dl.ac.uk] to try out these ideas.
The NSF (Nuclear Structure Facility -- for doing energetic heavy ion collisions -- nothing to do with nuclear weapons!) was built there in the late 1970s. That's the tower you can see in the site pictures. Unfortunatly SERC killed nuclear structure work in the UK in 1990. They pulled funding for the NSF and told people to look for beamtime at other sites outside the country. In fact the Recoil Seperator ended up at Oak Ridge, TN (so they didn't keep that expertise in the country).

NINA was decomissioned in the late 1970s and it was decided to build the Synchrotron Radition Source (SRS) using part of the old NINA site (and the NINA linac, I think) to provide a dedicated SR source in the UK for chemists, biologists, martials scientists and physicists.
All though this time a theory group was based there and a large regional computing facility (that used to have a Cray 1 in the good old days from 1979 to 1983) that was a major node on JANET (the academic network in the UK).
The SRS [dl.ac.uk] was comissioned in 1982. This is where the 20 years mentioned in the article comes in -- opened in 1982 and closed in 2003(ish). I not sure if they'll keep the SRS open although the parameters for the SRS and DIAMOND are rather different. DIAMOND is good for high brightness X-ray studies but not so good for soft X-ray or XUV uses.
I worked there as a (suface science) grad student (from Liverpool University) and got my PhD working on the TGM and GIM and SEXAFS stations on beamline 6 and later did some work on Beanline 1 when I worked at the Surface Science Center at Liverpool University.
The site had a lot of experitise for machine physics (the epople who understand how to keep the electrons going around the ring), beamline and monochromator design. I suspect some of these will move down south and another nothern resource will be lost.
I'm sure the RAL people are happy (the decision as made almost 2 years ago) but they don't have a site who boundary is formed by the Bridgewater Canal. Perhaps it's heading the same way as that old tech.
