Shift Checklist Help
- The How-to page is extremely helpful. Use Firefox's "Page search" to help find what you are looking for.
- There is also an older Shift Checklist help file, which may help to locate items. (But it is a stale document.) Below is an updated table.
What | Where to find it | How to do it |
---|---|---|
DATE (day-month-year) | As given by Run Control | Enter as DD-MM-YY |
Time (24-hour clock) | As given by Run Control | Write the time into the cell |
Your Name | As given by your parents | Write legibly |
Beam Conditions from Overview Screen, DAQ, MEDMs, and Scalers | ||
Beam Energy (MeV) | The Hall C Summary Screen should be displayed on a wall monitor. If not see this page to bring it up: EPICS/Accelerator_Screens. | Write down the Hall C beam energy |
Beam Current (uA) | Same as above | MPS and Hall C BCM readings should be similar. Record the
reading |
Beam position lock on? | Use jmenu and search for 'lock.' Then choose 'Orbit Locks Normal View
and look for 'HallCOrb.' It should be in green and show 'Running.' |
Write 'yes' or 'no' in the cell |
Beam energy lock on? | Use jmenu and search for 'lock.' Then choose 'Energy Locks.' | Write down the three colors: one for '0R, 1A, 2A.' (They should all be green. This indicates 'yes.') |
IPM3H07A, B, and C BPM positions. Are they nominal? | See the summary screen. | Record the displayed beam position. Compare it with the nominal position posted on
the white board or sticky note. |
Fast Raster Setpoints for Width,
Height (x, y) (mm) |
Use jmenu and search for 'fast raster.' The screen is "Hall C Raster Controls." | Record the set sizes in the “Set Raster Size” box. |
Fast Raster Measured Currents (Ix, Iy) (A) | Use jmenu and search for 'fast raster.' The screen is "Hall C Raster Controls." | Record the the four measured currents (Ix and Iy for two H and two V coils) from the
“Raster Measured Current” box. |
Raster visible on oscilloscope? | Go to the electronics room and verify the circular raster pattern on the oscilloscope screen. | Record 'yes' if you see one (you should! especially if beam is on!) If not, notify the TO and MCC. |
Beam Polarization/Parity Checks | ||
Helicity Reporting Delay (No Delay, ___ Windows) | Use jmenu and search for 'helicity,' then choose 'Helicity Control.' Look for 'Reporting Delay.' | Record the time of delay (it should be 8 windows). |
DAQ Quantities | ||
HMS Trigger Rate | On the CODA GUI Screen, next to the appropriate prescaler value (ps1 thru ps6). | Record the typical instantaneous rate |
SHMS Trigger Rate | On the CODA GUI Screen, next to the appropriate prescaler value (ps1 thru ps6). | Record the typical instantaneous rate |
HMS Dead Time | On the CODA GUI Screen, under the "computer live time" tab. | Calculate and record the average value |
SHMS Dead Time | On the CODA GUI Screen, under the "computer live time" tab. | Calculate and record the average value |
Hall C General Checks |
