3. Chambers in progress
BMC chamber
EIL1A09: Copper tubing to ETs installed and flushed gas.
EIL1C03: Copper tubing to ETs installed
EIL1C07: Copper tubing to ETs installed.
EIL2A07: taking cr data

UW:
8 BIM chambers that will be attached to EIL4
Gas leak certification of the chambers.
4. Problems and other issues
a) We almost have no chambers to work with due to the breakage of the
crane in the storage bldg for BMC chambers. Fortunately, a shipment
with 10 chambers arrived in time and we directly unload them in bldg
184 and keep us going.
c) A guy in the crane team is a beginner, we observed how the
chambers swings when he was operating the chamber yesterday
afternoon. I remined the other experienced operator. we should help
watch how they handle chambers in bldg184.
d) Ar gas was running out last night and we won't have it until this
afternoon.
e) The door to CMS bldg is fully open again this morning. We once
more ask you all working at BLDG to pay atention not to forget shut
the doors in bldg 184 before going home. We have many expensive
tools and equipments in bldg 184 and loss any of them will bring
negative effects to our work. So please pay attention and help us to
shut ALL doors before you leave.
