Hi All,
We will have a beam line meeting Monday at 10am in the Group C conference room. 
Last week’s meeting
Agenda:
- Beamline subsystem experts--those who can be on call over a one week period to resolve technical issues with the subsystem in question. Experts must be in residence at JLAB and will be available 24/7 to HPS shifters. (see email from John given below).
Stepan and Francois will be "beam line experts" for the 2014 run. Takashi agreed to learn and try to become a "Beamline Expert" before December 22, 2014. There will be a need for more beam line experts in 2015. Others expressed interest in becoming a beam line expert.
Duties of beam line expert includes:
1) Beamline expert should know the Hall-B systems.
2) Beamline expert needs to understand and be able to maintain/operate our part of the system and Hall-B devices including: 
 - Halo counters
 - Harps
 - HPS protection collimator
 - Beam viewers
 - Faraday cup
 - Beam stopper
 - HPS target including operating the stepping motors GUI to move the target (in coordination with the silicon and ecal detector groups and accelerator operation). 
 - HPS Silicon detector movement of layers 1 to 4 (in coordination with Silicon detector group and accelerator operations).
 - EPICS related stuff like scalers, GUIs and magnet controls.
 - other?
 

3) Most of beam related issues will be resolved with accelerator operations machine experts, not the Hall-B or experiment experts.  
- Neutrons shielding for front end boards - update: Takashi

- Schedule - update: Marco
no report made

- Target work - update: Clive and Marco
Designer should be starting soon. Target should be ready for checkout at SLAC before Silicon Detector moves to JLAB in mid-September.
- Other?

Subsystem Experts for upcoming HPS Shifts
"Dear HPS Subsystem Leaders,

HPS will begin running shifts this fall. Beamline commissioning shifts will run Oct. 10-Nov. 21; general HPS shifts will be run from Nov. 22-Dec. 22.

Official subsystems are: Beamline; SVT; ECal; TDAQ; Slow Controls
Onsite SVT experts should also be expert in SVT DAQ; backup SVT DAQ expertise at SLAC should be scheduled and available during the Nov. 22-Dec. 22 run period.

All official subystems should:
1) supply a list of subsystem experts--those who can be on call over a one week period to resolve technical issues with the subsystem in question. Experts must be in residence at JLAB and will be available 24/7 to HPS shifters.
2) schedule coverage for the period Nov. 22-Dec. 22 for your subsystem.

In addition, Beamline and Slow Controls should schedule coverage for Oct. 10-Nov. 21.

We'd like to get this information before next Wednesday, so EC can settle on shift assignments for the fall running soon.

Please let me know if there are questions/concerns.

Thanks,

John"
