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):

Some more layouts are available as well: East Hall and surroundings, IRRAD facilities, 3D panoramic views 1,2.

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.

More information (partly protected) is available in the EDMS area and here for topics in particular related to the upgrade and consolidation activities (please look also at the 'Structure' tab).


BEAM LINES

The T8 beam

The T8 beam is a primary beam that delivers primary protons to the irradiation facilities IRRAD and CHARM. Normally the beam momentum is 24 GeV/c.

The following information is available:

The T9 beam

The T9 beam is a secondary beam that delivers secondary particles up to 15 GeV/c at a production angle of 0 degrees.

The following information is available:

The T10 beam

The T10 beam is a secondary beam that delivers secondary particles up to 7 GeV/c at a production angle of 61.6 milliradians.

The following information is available:

The T11 beam

The T11 beam is a secondary beam that delivers secondary particles up to 3.5 GeV/c at a production angle of 149.2 milliradians.

The following information is available:

The primary beams

The primary beam from the PS extraction to the targets consists of a common section up to the septum, called F61, the F61N branch from the septum to the North target and the F61S branch matching into the T8 beam for CHARM and IRRAD

The following information is available:


GENERAL INFORMATION

Beam Control

A illustrated guide to the control of the secondary beams is available here (PDF) (PPT).
A quick user guide for the test beams cCesar control is available here.

Access

The following information exists concerning access to the secondary areas:

  • How to take and end an access
  • For CHARM and IRRAD users, access rights for their zone IRRADS (P) must be asked for via EDH
