General How-to's
- The Hall C Operations Manual is a thorough and up-to-date set of instructions.
- Make HCLog entries using the logbook page, or by running 'hclog' in a terminal.
- Please be concise, but clear. Assume you will need to search for, and understand, an entry 12 months from now (or longer).
- Electronic Shift Checklist should be completed once per shift.
- Hall C Raster
- If problems call Raster experts in order of listed on Expert on call page.
- Raster procedure is located at Hall C Fast Raster Setup Procedure
- The raster X and Y signals that go into the DAQ are also shown on an oscilliscope in rack CH03B14. See logbook entry for a movie of good oscilliscope signals. The X and Y should be 90 degrees out of phase and the amplitude variation in sync.
- If raster signal's amplitude variation is not in sync, then ask MMC to go to the "Waveform Generator" page ( top right corner of the Hall C fast raster page). On the "Waveform Generator" page have MCC click on the "SYNC ARB" button.
- If raster signal's phase is not 90 degrees, then ask MMC to go to the "Waveform Generator" page ( top right corner of the Hall C fast raster page). On the "Waveform Generator" page have MCC click on the "SYNC PHASE" button.
