keyword=Parity Inj DAQ tests.

Database template file has been fixed.

Swapped polarity of the cables to the sample and hold cards. They are now looking at the connections that are labelled as negative (e.g. -X+, -X-, -Y+, -Y-).

Made some runs to see if my changes at the injector bpms worked. Tuned Beam (about 6 uA) was running through injector (up through 5MeV region) at the time.



Run    Result



5249   Waited for atleast one beam trip.

        Scaler  0- 7: Agree with ADC0_1-4  

                       Must be very little beam.  Gain jumps when beam

                       goes off.

        Scaler     8: Gain drops a bit when beam off.  Probably ok.

        Scaler  9-11: Same as 0-7.   

        Scaler 12-14: No relation to ADCs or other Scaler Channels.

                       Maybe MCC is doing something strange.

        Scaler    15: Nothing.



5250   All scalers (except for 15) seem to be doing the same as the ADCs

        (channel 8 still shows a drop in gain, during a trip).   

        Went back to ISB to check on channel 15.



5151   Flipped v/f switch from nothing to "Ch 16".

        Channel 15 looks fine now.

Pedestals will need to be calibrated.

Going home now.
