View source for Run plan/To do list - Tuesday, December 19 2017 - day shift

== Notices ==
# SHMS DIPOLE MAX CURRENT IS 2100 A
# Do not rotate either SHMS or HMS if the HMS dipole current is above 2500 A
# The SHMS angle is currently 7.5 degrees. ONLY ROTATE TO LARGER ANGLES. 
## Once we have rotated to larger angle, the minimum angle will be 10 degrees.
## Smaller SHMS angles will require an access and assistance from Steve Lassiter/Mike Fowler
# Nominal beam positions (for now): x=-1.0, y=-0.75 at IPM3H07C
# Be sure to fill out the beam time accounting - edit the form as necessary. The values "auto-filled" from EPICS are not always accurate.

* Overview
  Controlled access at 8:30 for target cooldown
  Continue owl shift program as needed:
  Check SHMS tune with carbon elastics at 7.5 degrees. Take data in HMS "parasitically" to check scintillator and PID thresholds in trigger.
* SHMS carbon elastics at 7.5 degrees - will check/establish SHMS tune
  SHMS settings: P=2.214 GeV, Theta=7.45 degrees 

* HMS threshold scan
  HMS settings: P=1.0 geV, Theta=14.01 degrees

  Take 15 minutes runs at 10 muA with HMS Hodoscopes discriminator thresholds at: 30 mV, 20 mV, 40 mV and 50 mV. (Expert: Simona M.)

  Trigger Threshold Scan: Insert target 0.5% Carbon and take 15 minutes runs at 10 muA with various thresholds for the CER and PRESHOWER/SHOWER PID legs of the trigger (Expert: Eric P.)
