Dear all,
here's an attempt to give an update on some of the planned activities in
the hall tomorrow (Friday July 8).
Survey:
The survey of Lumi and Tof components will continue in the morning.
The elastic lumi telescopes of 3 GEMs and 3 MWPCs have been surveyed
internally and mounted in the detector this week. Survey of the telescopes
w.r.t. the wire chambers has been started today.
TOF18 in both sectors was added today, the rear TOF groups will be
surveyed tomorrow.
OLYMPUS wrapping:
The crane group will arrive at 10am. The second Argus muon chamber will be
placed on the main frame above the left sector. Two 6mx25m plastic foils
will be pulled over the detector from the upstream to downstream end to
wrap the detector. The sides will be covered with additional 5mx6m plastic
foil curtains.
Cabeling:
Cabeling of the lumi telescopes is ongoing, first with MWPCs, GEMs to
follow.
Wire chamber repairs:
Work in progress.
TOFs:
Debugging of PMT signals is ongoing.
This weekend will be the last opportunity to work on the detector before
the rolling-in. From Monday-Wednesday July 11-13 the hall will not be not
accessible, to allow the crane group to remove the shielding and transfer
the concrete across the detector and the electronics hut to the DORIS hall
floor without interruptions.
Best regards
Michael
