FAIR Commissioning Phase A.1.1.01) -- Commission Final Meters of Preceding Transfer Line

Specifics

For details of the commissioning of the lcoal injector see topic "Commissioning of the Local Injector"

Scope of Phase

The following sections shall be defined as "the final meters of the injection section":
  • Part of beam line GHTY between gate valve GHTYVV1T (exclusive) and gate valve GHTYVV2T (inclusive). In detail the following components and technical systems are involved:
    • Vaccum:
    • Beam optics + related power converters
      • vertical steerer GHTYKV3
      • quadrupole doublet lens GHTYQD41, GHTYQD42
    • Beam diagnostics
      • diagnostic chamber GHTYDK3 with
        • Cromox fluorescent screen GHTYDF3 + pneumatic actuator GHTYDF3_P
    • Control System
      • Timing System
      • End user applications + related controls stack

For Details see CryringWiki page " GHTY Transferline Details"

Description

Goal of this commissioning phase is to thread the beam from ESR up to detection box GHTYDK3 and check operation-readyness of all active elements in this section.
  • Vacuum < 10<sup>-9</sup> mbar (10<sup>-11</sup> mbar for stored beam operation)
  • Beam can be manipulated according to expectations with GHTYKV3, GHTYQD4x
  • Beam spot is visible on GHTYDF3 with spot size of XXX mm
