October 5, 2011 online meeting minutes

present: Sergey Boyarinov, Sergey Pozdnyakov, Eugene Pasyuk, FX, Nerses, Hovanes

1. Cables in inventory database: Eugene presented the idea how to implement connections and cables into inventory database; after discussion following database tables were proposed:

-
connections
id pin1_id pin2_id 
-
pins
id connector_id local_pin_id?
-
connectors
id type Npins host_id
-
cables
id s/n type locical_name(label_on_cable)
-
boards (exist)
id s/n type ...

We decided to go through all possible database operations (board removing, board replacing, board moving etc) to see how proposed scheme will be fitted in. It will be discussed again on the following meeting. After desicion is made, it have to be implemented into current inventory dataase and web interface.

2. Electronics testing:

• FADC will be moved to the Hall for testing with real detectors; it will be installed into sc3 VME64X crate and connected to the 15 TDC outputs of the EC splitter (TDCs will be disconnected) such way so 5 Us, 5Vs and 5Ws forms triangle area; data from both FADC and 1881 will be collected and cosmic calibration will be performed and results compared; prior to that test regular EC calibration for entire calorimeter will be performed and all necessary repair will be made

• v1190/v1290 testing is under way, Sergey P. uploading results in CAEN v1190

3. Drift Chamber cosmic test and upcoming run preparations: cables on the floor were repaired, DC1 was fixed, may need to repair FASTBUS WIENER power supply, ready to run DAQ
