1. 11/10/98Online Meeting Julia Velkovska Running and Monitoring the PHENIX Drift Chamber Julia Velkovska and Tom Hemmick

2. 11/10/98Online Meeting Julia Velkovska Turn on the DC electronics u Water cooling ON - monitor T and flow using ADAM u LV supply ONCS panel On/Off Read V,I and compare to last run - DB access u Synchronize the Timing Glink ONCS - GTM fill frames DC - read HeapMgr CSR and confirm lock ONCS - normal running These steps should be one command in the future

3. 11/10/98Online Meeting Julia Velkovska ArcNet Communications u Network map - who is alive? u Read Temp sensor CSRs - get geographic addresses and board serial #s - output to tape u generic INIT - load HeapMgr and TMC CSRs u threshold DACs - need DB access u Throughout the running - polling CSRs to monitor Temperature and TMC errors - dump into the Data Distributor

4. 11/10/98Online Meeting Julia Velkovska DC ready to send data u Lock FEM-DCM Glink FEM s are programmed to send fill frames all the time except when sending data ONCS - verify the FEM-DCM lock through VME u PULSE ONCS - program the GTM mode bits to issue a test pulse and a LV1 trigger to the FEM, Begin Run, DD - Staf DC - Staf code to verify the pulse, check detector noise level, adjust thresholds, need DB access

5. 11/10/98Online Meeting Julia Velkovska Electronics ready - DC turn ON u Flow gas - DC/PC/TEC using ADAM ? In mixing hut and on carriage u HV on - data base with target values and gain curve u DATA

6. 11/10/98Online Meeting Julia Velkovska Ancilliary systems u Canary chamber monitoring the charge carriers drift velocity in the DC gas LV - DC to DC converter HV - from the last keystone DC code to initialize, run, read data via ArcNet ONCS - insert data into the DD u Gas analyzer

7. 11/10/98Online Meeting Julia Velkovska Monitoring ONCS u example page with fake histograms how many per subsystem ? u framework within which a person on shift will look at the histograms u history info - call up another run and compare DC u monitoring of detailed “ only for experts” data pages u schedule pulser events

8. 11/10/98Online Meeting Julia Velkovska What else do we need... u Collect variety of readings through ArcNet and archive them - T sensors, error registers, canary chamber data u What if something goes wrong… audible ALARMS
