  • Production data (Kin48_3)

Specific mission

      • Continue production mode ***

last update Feb 29

  • Polarized beam at 15 uA on LH2 15 cm through Compton chicane !
  • DVCS is running kin_48_3 [here], as off 02-29 10 am we have accumulate 1 C out of our goal of 4.7 C.
  • LHRS is partially detuned: [here]
- LHRS=2.92GeV, Q1/Q2/Q3=1916.640(readout:1900)/1600/1600 (Q1 regul.OFF)
- PreScaleR : PS1=PS2=PS3=1, && PS8=200
- PreScaleL : PS9 =1, + DVCS config.
  • beam locks: no position lock, energy lock in Arc 2: [here]
  • the straw chambers in the LHRS are off
  • DVCS daq configuration is [this one], we are measuring about 2% DT at 15uA.
  • Take Compton run every 2 h

Re-establishing beam through chicane

- 9AM, Now beam goes through Compton chicane | HALOG

BPM/Spot++ Check

  • After beam lost for considerable time (like beam study, pass change,...)
  • Ask MCC to run 5uA wth carbon hole target and make sure you can see the hole through Spot++

Please check more info on the white board in the Counting House ~!!
