FAIR Commissioning Phase A0.1) -- Commissioning of the Local Injector

Scope of This Phase

The following parts and devices of the CRYRING@ERS beamline shall be defined as the "Local Injector":

All equipment upstream of the vacuum valve YRT1VV4T including dipole magnet YRT1MH2 (a.k.a. "merging magnet", "35 degree magnet". In detail the following components and technical systems shall be considered:

Description

(N.B. priority definition 1: must, 2: optional, 3: nice to have, if time available -- 2&3: optional items, e.g. for night-time shift or if commissioning delayed by another item)

To be considered: required time - minimum (rough estimate, smallest time quantity 1h, otherwise given in terms of 8h shifts) required time - contingency (rough estimate, subjective at this time but should not reflect worst-case)
