TECHNICAL HOMEPAGE

MANDATE

The EA group is responsible for the secondary beam lines downstream of the SPS primary targets T1 (West Area), T2, T4 and T6 (North Area). A synoptical diagram of the beamlines is available here. These beamlines serve a variety of experiments and test facilities. The group is responsible for the liaison with the users of these facilities and it provides support for their installation and infrastructure.
Part of the group is involved in the CNGS project, providing a long baseline neutrino beam to the Gran Sasso laboratory near Rome.

ACTIVITIES

The responsibilities for the various beamlines and zones are shared by five beam and liaison physicists:

West Area :	Per Grafström	H3
West Area :	Lau Gatignon	H3, X5, X7
North Area :	Niels Doble	H2, P42+K12
	Per Grafström	H4
	Ilias Efthymiopoulos	H6, H8
	Lau Gatignon	M2, P41/P61
LEP experiments :	Georg von Holtey
CNGS project :	Konrad Elsener

Both beamlines and experimental areas have to be adapted continuously to the needs and requirements of the experiments and tests. The work related to these changes is discussed in the SPS Experimental Areas Technical Committee (SEAT). The EA group comprises a Engineering and Installation section , headed by Michel Clement. Within this section, Claude Ferrari is responsible for the installation of the experiments.

The secretary of the EA group is Madeleine Catin

OPERATION

The exploitation of the secondary beam lines is assured 24 hours per day, 7 days per week with the help of the CRN operations section , headed by Bruno Chauchaix.
The present ststus of the beams is shown in Teletext page 195. The contents of this screen are explained here. The state of the SPS machine operation (PCR -> SL/OP group) can be read from the so-called Page-1TV-screens.
