Power Supplies & Vacuum Mostly standard components, no special demands  uncritical

Beam Diagnostics No detailled schedule yet, but: EoI of GSI work already in progress, next to the target: simple detectors (SEM, CERN beam loss monitors) in separator: standard devices (BPMs, screens, grids) which, however, must be adapted for the large beam sizes (similar to Super-FRS and CR).  no time critical devices recognized

Target Station

Target Station

Target Al block Ti window inside: Ni rod (r = 0.15 cm, l = 10 cm) within graphite cylinder (r = 1 cm) air cooling

Target

Magnetic Horn + 400 kA Pulser

Magnetic Horn + 400 kA Pulser A pulser is needed for these tests

Summary delayed: magnets (1 production line) critical: horn pulser less critical: target station, horn uncritical: magnets (2 production lines), vacuum, BD, target, power supplies
