Minutes of the Forward Endcap EMC Meeting, 15th of April 2024, 14:00 - 15:15
Preparation of Moving FWEC to Bonn:
A removal of the radiation protection wall surrounding the TOF hall might be possible (Fritz-Herbert talked to Ralf Gebel about that). However, we agreed that a removal would only minimal improve the procedure of getting the detector out of the hall and onto the truck. Given that a timeline for a possible removal is fully unclear we decided not to ask for it but stay with the procedure developed in the past weeks
For rack space planning in Bonn 3 Us should be reserved for the light pulser reference system. By doing so we still have about 13 Us spare.
The pedestal mounted to the Dalmec manipulator arm weighs 300 kg
Manual of the manipulator arm is still missing (maybe Malte knows about it?)
Something to remember when preparing the FWEC for transport: The brass feet need to be fully srewed in before securing the FWEC to the transport frame
We decided to mount an 'inner wooden shield' to front and back lid and let the detector prepared that way box by the transport company
Wood we need should be purchased locally at the Juelich hardware stores and trimmed by us using a jigsaw
Removal of the cooling lines/chiller is foreseen for next week (Claudius, Tom)
Malte and Fabian will prepare 8 commercial high precision PT sensors connected to THMP compatible cables to be sent to Bonn plus one newly calibrated THMP (somewhat later)
How many submodules would need a T-sensor recalibration?
Light fibres: We need to think of a mounting/suspension plan when fully equipping the FWEC with all submodules in order to not end up with a fibre spaghetti mess
An additional fibre connection inside the detector that would drastically improve the mounting is no option and was intentionally omitted as a source of instability (experience from BaBar light pulser system)
The number/ratio of finished fibre bundles needs to be looked up but should be high (Swetlana is preparing them since about a year)
