Storage Cell Tests at ANKE(R. Engels, B. Lorentz, F. Rathmann, H. Seyfarth …) • ANKE with PIT • New Targetchamber installed! • Tests using an Aperture • Preparation for tests with cells
Goal: ANKE Spectrometer with a polarized internal storage cell target
New Targetchamber Needed for: • Accomodation of the storage cell of the PIT • Flexible use with • Cluster Target • Pellet Target • Space for Installation of a vertex/spectator detector • BPM system up/downstream of cell (x vs y) • Differential pumping • Still Missing: • ABS Bridge • LSP Support • Supports for setup in Bermuda
Chamber prior to installation(Winter shutdown 2002/2003) ZAT! Beam
ANKE BPM (upstream) • Movable, acceptance limit. of backward detector beam
Aperture Tests • Aperture mounted on horizontal strip target support • Beam Steering capabilities improved around ANKE (SH30SV30) • With a vertical four-steerer bump (SV24+SV26) and (SV28 SV30), orbit bump at ANKE small! Without aperture: 21010 With Aperture: 9.4109 2.44 GeV/c March 2002
Equipment for Cell tests Two xy Tables Window frame (25 mm 50 mm) beam
Planned Measurements • Install equipment (xy tables + frame) after long summer run • Goal: Find cell dimensions • Tests with Cluster Target no target dt=1.41014 cm-2 dt=41014 cm-2 M.A. Ross et al. NIM A 326, 424 (1993)
