Attendees: Malte, Scott, Josh (Ballard), Eugene, Tim, Simon, Zisis; Regrets: Sasha
- Announcements
- Zisis introduced the resurrection of these meetings to meet our timelines and be ready for beam in January. This requires efficient communication and adhering to timelines and coordinating activities among the groups (FCAL, ECAL, Mechanical, a.o.).
- Tim mentioned that the hall should be ready for physics on January 24, meaning that it should be closed no less than a few days before. The tasks to get there require a final survey of the detectors, and of course the dark box closed and the TOF moved into position.
- Detector:
- FCAL:
- Malte supports a clear schedule and meshing of the work of job crews. We need milestone dates and Tim showed some of those (see below).
- Lead Glass: all cabled, all bases powered to check communications, LED strands checked (see logbook). Remaining issues: a) IOC communications and Hovanes is helping; b) a few LEMO cables need repairs.
- It was decided to examine the waveforms of the signals and revert to an oscilloscope if needed for debugging. Sergei told Malte that a a reduced DAQ can be run without a Trigger Supervisor (TS) at this stage.
- Schedule: 2-3 1/2 calendar days for IOC and 1 week for waveform checks.
- Cosmics need to be taken. Coordination with Sasha on using suitable scintillator paddles above and below FCAL2 should be done. Cosmics may need to run for several weeks. Eugene suggested a quick test to see what the rates are. Cosmics wil need the full DAQ with TS.
- ECAL translation tables are ready and implemented by Sasha in the database (XML) and run numbers will go 130XXX. The Lead Glass ones need some work.
- ECAL: See JEF meetings for details
- FCAL:
- Mechanical:
- Tim showed the schedule with dependencies, as these are known at present. Interaction with Sasha is needed to refine some of them.
- Tim reported that he has received some input from Sasha which was incorporated in this GANTT chart, with dependencies. More details are needed from Sasha to help shape the schedule and the activities.
- The dark room has its permanent sides, except for the front face which has a tedlar curtain for easy access at this stage. Caulking is pending.
- Sasha will discuss the HV panel boxes needed with Tim this afternoon.
- Insulation is 90% done, except the cable ports. 2-cm-thick foam will be installed on the front face. Eugene emphasized the need for temperature stability over the actual temp (17 C planned). Tim said that two 4kW chillers will be used.
- Tim's schedule has the dark room finalized on December 6, but Eugene suggested that Nov 20 might be a safer target,
- It was decided that the interlock will be reactivated and a key needed to access the dark room, to prevent entry that has not been coordinated.
- Electrical:
- Tim is interacting with Fernando on the temp box (proper grounding etc).
- Electronics/DAQ
- Any other business:
- Malte will work on creating a Teams/Google/... project calendar for our efforts.
