CERN has a superb interactive map showing the different points where HLC is located : http://building.web.cern.ch/building/ & http://ts-dep.web.cern.ch/ts-dep/groups/fm/ts-fm-isp/fr/patrim5_v8.jpg

I heard from a scientist at Fermilab in March that CERN will be taking over major, large-scale particle acceleration projects. Is this still holding true? If so, will Fermilab cut some jobs at its establishment if such projects are under CERN’s control?

Your paragraph about the APS and how synchrotrons are used is inaccurate.

A better description:

Particles (electrons) traveling around the storage ring in ultra high vacuum and at the speed of light, go through magnetic fields which make them emit laser-like beams of x-rays which are sent onto mirrors and stuff to do experiments in which we study the interaction of the x-rays with matter to get information on atomic and molecular systems.

It is the synchrotron radiation (mainly xrays) that is used in experiments, not the particles used to produce it.

haydesigner, You are probably thinking of the SSC (Superconducting Supercollider) which was mentioned in the 4th post. It was to be a very large accelerator, the ring of the SSC being over 80 km in circumference, and collide two proton beams (or was it a proton-antiproton collider?) of 20 TeV each. The LHC at CERN will be the highest energy particle accelerator in the world when it is finished and it is only 27 km in circumference, and will collide two proton beams, each of 7 TeV. So, comparing the two the SSC was indeed massive.

12,

Wasn’t there a MASSIVE one planned and started in Texas about 10 or so years ago? But it only got about 25% dug, and then the GOP Congress killed? Or am I crazy?

It also goes under a very busy freeway (US 280), so they must not be too concerned about vibration.

Interesting choice of location for the SLAC. If you zoom out a little bit, you can see that the accelerator is only about a mile to the east of the San Andreas Fault (the fault is the linear feature running under the reservoir in the northwest towards the southeast): Placemark: Google Maps / Google Earth

I wonder how much an earthquake would damage its reputation of world’s stratest object.

Finally! A submission I made many months ago (SLAC) gets used, and you misspell my name! Well, you also missed your chance at cosmic irony (or some statement on humanity’s eternal quest for knowledge?) by not putting this post about the modern huge circular structures built to explore the fringes of science, next to the prehistoric Avebury ring structure built to…what?

If this: http://www.balu.sk/fotky/cern/cern_full.jpg is correct, then I went ahead and placemarked all the circled buildings in google earth. Here is the KZM file:
