CRYRING@ESR - Facility for Antiproton and Ion Research

32 Chapter 7. Project Steering
reassembling it in the Target Hall at GSI has been worked out already by the BES division,
responsible for all mechanical work packages. The plan supposes that the start of the activities
takes place in August 2012.
7.2 Cost and Manpower Requirements
The cost and man power requirements for the realization of CRYRING@ESR were analyzed
in detail. We have completed our analysis for two scenarios, a minimal solution and a FAIR
compatible setup. A minimal solution adapts the ring mostly as it is to the GSI infrastructure.
The cost estimate for the minimal solution is 1 190 k and includes all work performed by
external companies. Moreover, 290 man weeks for the installation need to be provided by GSI,
i.e. its infrastructure divisions (about 7–8 man years). It shall be noted, that this estimate
does not yet include the costs for installation and commissioning of the main ring magnet power
supplies; there, negotiations with external companies are still ongoing.
The FAIR compatible solution will require additional expenses of 717 k and additional 197
man weeks. These additional expenses should be covered by the FAIR budget (for test benches
and hardware commissioning).
The majority of cost estimates are based on careful calculations by experts from technical
divisions. Some items are still rough estimates, some may be too high and less expensive
alternatives are under investigation by the EET division.
7.3 Project Structure: Installation and Operation
For the installation of CRYRING at the ESR and finally for its operation, a dedicated project
team is required. This team will be responsible for the organization, coordination, and physics
performance of CRYRING@ESR (see Organization Figure 7.2). Project During Phasethe installation phase, it needs to

act in close cooperation with the teams of GSI infrastructure and will coordinate in addition
the support by external groups, such as by the colleagues from Sweden. After the building up
phase, the project team will change its profile and takes over the responsibility for operation
(Figure 7.3). Basically, the group members will nearly remain the same but their tasks will
be directed towards operation, maintenance, and the demands of the FAIR project (test of
novel beam diagnostics, controls etc.). Members of the atomic physics division will act as the
core of the project team. Most of them are already involved into the HITRAP project and its
commissioning. Since from physical and technical point of view HITRAP and CRYRING are
closely entangled (both HITRAP and CRYRING are the central facilities within the FLAIR
building), the merging of both projects appears to be evident. The time and resource planning
for HITRAP need to be adjusted accordingly. The assignment of personnel as well as the use of
