Run2c Beamlines Coordination Meeting: Power Converters
→
Europe/Zurich
865/1-D03 - SY-ABT Conference room (CERN)
Description
This meeting is intended to review the overall status of the AWAKE Run2c beamlines and ensure coordination between the different teams involved. The objective is to monitor progress, identify potential issues early, and ensure that all required inputs and documentation are available.
During the meeting we will cover:
-
Design progress
-
Procurement status
-
Missing inputs
-
Availability and status of documentation
This particular meeting will help highlight showstoppers and define actions needed to keep the design, procurement, and installation of the beamlines power converters on schedule.
Participants: Eleonora Belli (EB), Serge Pittet (SP)
Discussion Points:
150 MeV electron line (TT451)
The 150 MeV electron line will use a new family of power converters (MEXICO) with a new controller.
All the units will be manufactured at CERN, as there is no time for external production. 12 units at 25 A will be installed in AD during LS3. Once these units are validated, EPC will start the 50 A version for AWAKE, which should proceed much faster. This phase is expected to start in 2027.
In order to prepare the functional specifications, EPC is missing the following input:
-
Circuit names: a preliminary version of the 150 MeV line layout with the corresponding functional positions was shared this morning. However, magnet codes are needed to finalise the plan
-
Action: EB to provide the list of circuit names, once the final layout is available.
-
-
Operational mode, final number of magnets, and whether they are powered in series, in parallel, or individually
-
Action: EB to provide.
-
-
Design report of each magnet (existing and to be produced), which will help decide which type and how many MEXICO converters to use
-
Action: MSC to provide.
-
Urgent request
The FGC4 control system for the MEXICO power converters has proven to be more demanding than initially expected. In addition, the people originally identified for this work are currently heavily involved in HL-LHC activities and in the preparatory work for FCC studies, which significantly limits their availability.
To ensure the proper design, validation, and production of the converters and their control system, additional dedicated support is therefore required. They propose allocating an ORIGIN (Electrical or Electronics Engineering Entry-Level – University Graduates) to support this work. Considering the expected workload, this support would be needed for at least 12–16 months.
Although this was not foreseen initially, it is considered the only way to meet the AWAKE schedule.
Action: EB to inform Edda, budget to be updated for MTP.
