The East Area is an experimental area at the PS, located in building 157. It contains five beam lines: T7, T8, T9, T10 and T11. A schematic view of the beam line geometry is available here. Also available are a synoptics and a schematic layout of the user zones in 2006. The detailed overall layout drawing is shown below (click on the picture for access to a A0 format PDF file):
The beam lines are derived from the 24 GeV/c primary beam from the PS, which
provides 2.4 second cycles with a flat top of about 400 msec. Some cycles serve
the North target (for the T9, T10 and T11 beams), some the South target (for T7
and T8).The number of East Area cycles per supercycle depends on schedule
constraints. Each cycle has a flat top of about 400 msec, with (in theory) uniform time distribution.
Details about the general layout and beam sharing can be found
here.
Some of the characteristics are shown in posters of the East Area as a whole and
more specifically of its test beams.
The PS/SPS Coordinator maintains a
web site with
schedule related and other relevant information.
Detailed information can be
obtained from the liaison
physicist responsible for the East Area.
The T7 beam is a secondary beam that delivers secondary particles up to 10 GeV/c at a production angle of 0 degrees.
