11/6/08 : After several e-mail exchanges a final invoice version (#5?) is sent to LaTech which based on the lack of a reply is assumed to satisfy their needs.
11/19/08: Tony reports construction complete at Qweak collaboration meeting. Detector testing needs to be done but due to LaTech's grant expiration induced emergency, only a HV test was completed and the detectors were sent to LaTech for property tags.
11/24/08: 2 Qweak GEM detectors arrive at LaTex according to FedEx tracking.
1/12-15/08: Tony sends Greg 1/4 report suggesting that communication take place concerning the last R1 milestone delay
1/19/09: Klaus tells Greg that the last R1 milestone is delayed from March, 09 until Oct. 09. Tony has no idea where this number comes from and was never contacted for discussion.
1/20/09: Klaus submits critic on GEM detector construction to Greg Smith and the R1 work package leader
1/21/09: Greg e-mails an evaluation of Klaus' critics by an outside expert. The expert does not find merit with Klaus' critique which would warrant corrective action on the detector design.
1/23/09: ~2 hour phone conference
- summary
- The teleconference concluded without identifying any problems with the GEM detectors that needs to be corrected.
- A considerable amount of time was spend on gas leak tests. LaTech did not seem to accept the outside experts opinion regarding chamber gas leaks and will try to perform a leak test measurement. Is important to consider that the charge collector is the only critical component which must not be damaged. The charge collector has a thin gold coating to reduce the impact of Ozone and H2O. The GEM preamps and cathodes are easy to replace or repair (less than 1 day. Klaus should make detector attachement system which allows easy and fast detector removal.
- Latech urgency for detector delivery prevented most tests except for a HV test. Latech said they would return a detector next week. as part of the original plan back in November, next
- Some time was spent discussing the electronics readout. Steve ansswered Kathleen's questions requarding readout electronics game plan. Latech will look into a backup plan involving the BONUS's RPC chambers readout electronics.
