- Production data (Kin48_3)
Specific mission
- Continue production mode ***
last update Mar 06
- Polarized beam at 15 uA on LH2 15 cm through Compton chicane !
- DVCS is running kin_48_3 [here], as off 03-06 5 pm we have accumulate 2.14 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
- Preparation Elastic measurement
- 6:30AM Call MCC for Controlled Access
- 7:30AM Change polarity and angle of LHRS (detail info will be sent to Jessi by email)
- 8:30AM-1:30PM various DVCS angle calibrations (required multiple escorted access)
- 2:00PM Change polarity back and angle LHRS for production
- 3:00PM Resume production
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 ~!!
