Dear all,

Please see the meeting minutes from this week's pfRICH engineering meeting.

Many thanks

Bill

Summary

The team discussed updating the schedule to meet the August deadline for 
the construction project. Sushrut suggested moving the tests to SBU and 
using a two by two sensor plane prototype for sealing tests. Bill 
requested a four-week extension for evaporator upgrade to be included in 
the coating schedule. Alex raised concerns about potential heat impact 
on detector systems during the beam pipe bakeout procedure.

Key Points
• Alex initiates a discussion about updating the schedule to ensure 
meeting the August deadline and addresses the impact of delivery delays 
on the project timeline. (0:24)

• Sushrut expresses the necessity of conducting sealing tests, proposes 
sending one end ring first for testing, and suggests shifting the tests 
to SBU if needed. (4:01)

• Sushrut suggests moving the sealing tests to SBU and provides details 
on the timeline for manufacturing the sensor plane prototype. (10:32)

• Sushrut explains the idea of conducting a sealing test using a two by 
two sensor plane prototype and acrylic sheet to check the seal's 
strength under pressure. (15:51)

• Alex suggests pressurizing instead of vacuuming for the test, with 
others agreeing on applying regulated pressure for the experiment. (21:32)

• Sushrut suggests informing the sealing choice for sensors and ensuring 
the bolting pattern is suitable, emphasizing the importance of avoiding 
late-stage redesigns in the process. (31:45)

• Bill and Preet updates the team on the coating schedule, requesting an 
extension of four weeks due to ongoing upgrades and pending tasks, 
including testing and mounting mirror brackets. (47:39)

• Alex raises concerns about the potential heat impact on detector 
systems during the beam pipe bakeout procedure, seeking clarification 
before making official announcements. (53:24)


Next Steps
• Sushrut to ship the end rings by the end of this week or next week for 
the sealing tests. (6:14)

• Sushrut to shift the sealing tests to SBU and figure out in June if a 
visit is needed or instructions can be provided to Charles, Bill, and 
their team at SPU. (13:29)

• Sushrut to talk to Alex and Charles to refine the plan for doing the 
sealing tests and present a better version in the upcoming meetings. (33:53)

• Preet to prepare 70 by 70 centimeter samples for future testing 
without the need for precision cutting, as discussed with Alexander and 
Bill. (42:07)

• Benny to ask Makoto about the costs implications of the increasing 
number of tiles and the recent limitations communicated. (1:07:44)
