AOB

Follow up on additional BPMs in the PSB Transfer Lines request

• ABT is responsible for this activity, including ECRs, DICs, etc... .
• The work units have been created: J. Tan is the responsible and S. Prodon will move the money there.

Comments:

• B. Mikulec: 1 coordinator from ABT is needed. Proposal for the ECRs:
  • An ECR for the injection line exists already. A new ECR for BPM in BI should be prepared.
  • An ECR for the extraction lines does not exist yet. A chapter concerning the new BPM should be included.

Tour de table

• S. Pittet would like to include a short review on the injection Q-strips at at the next LIU-PSB working group meeting. An AOB of 5-10 minutes would be sufficient.
• E. Fortescue-Beck reminded that the deadline for YETS hardware requests is END of September.
• B. Mikulec mentioned an issue with the injection watchdog. 16 OASIS signals were requested but the current hardware has not a large enough capability. An additional installation might be necessary.
• J. Hansen has contacted S. Prodon to discuss the budget but not answer received yet. He asked to A. Newborough if he can start the integration of the vacuum chambers: A. Newborough confirmed that few new magnet modules have been provided (at their best knowledge). Drawings were already approved and available.
• G.M. Georgiev asked for a meeting with CO and B. Mikulec in order to the define the installation priorities for the YETS. G.M. Georgiev will need this information before the 28^th of September.
• F. Schmidt is working on the digitization of the "old" PSB and PS documentation and he found a paper from the 1968 about the dump resistors. To be checked if the numbers there are still valid. Work in progress.
• B. Mikulec asked to A. Newborough if he knows the measurments that M. Buzio needs to do, but A. Newborough has not heard anything about it.

Next LIU-PSB meeting: 26^th of September.
