The East Area is an experimental area at the PS, located in building 157. It contains four beam lines: 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 2014. 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 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 (2012 layout) and more specifically of its test beams (still up-to-date). In the 2013/2014 shutdown a major upgrade of the South part of the hall took place; details are available on this poster.A detailed description of the project is still in draft form. 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.
