CERN Courier, May 1988 Bakeout of the LEP vacuum chamber with superheated water. LEP progress The first 1.5 kilometre (3x474 m) section of vacuum pipe in the LEP ring has been pumped down to the design level of about 10~11 torr. With these vacua, a high energy LEP electron could circulate for a third of a light year be­ fore running a serious risk of colliding with a residual gas molecule I When operating, synchrotron radiation from the circulating electrons and positrons will affect the LEP vacuum, giving a few 10~9 torr, when the particles' aver­ age undisturbed circulation time would be about a day. The vacuum in LEP's lead- clad aluminium beam pipe is now a permanent feature, and awaits initial test beams this summer. Several kilometres of LEP magnets are how installed in the 27 kilometre tunnel, in line with the goal of having the mammoth machine com­ plete next summer. Mean­ while the huge magnet for the L3 experiment at Point 2 takes shape, and work gets underway at Point 4 150 metres below the surface for final assembly of the Aleph experiment. Staff of the US National Superconducting Laboratory at Michigan State University took advantage of the last opportunity to pose before the concrete wall being built for the K800 cyclotron will hide it from view.
