ALICE #no elog
- MTR
- Dummy chamber: to ask to Arturo for manpower to install the pipes
- TPC
- To check with Fred for filters and distribution rack to put in place
ATLAS #1930
- New o-rings ordered and under aging-test: results on week 34
- It looks ok for VITON and some aging for EPLF
- TRT
- Exhaust in the distribution modification to finish this week
- MDT
- Rack 68 (ch 17): one channel is keeping going to zero —> try to change the ELMB
CMS #no elog
- RPC
- DT
- ELMB changed for the ELMB++ in rack 65 on Friday for a test —> Michal to give a summary
- In general: before doing test in system: discuss internally
- Pressure sensor on filter pump modified by adding 1/8 pipe as impedance: not enough, still fluctuation —> to increase the length of the pipe —> Andrea
