Revision as of 14:23, 4 February 2011
The following is a concise outline of the logistics pertaining to the beam test in Hall B in the Spring of 2011. The detectors under test are: Hall D Tagger Microscope prototype and Hall D Active Collimator.
Contents
Time
Prototypes ready for installation during the Feb 25 - Mar 28th Hall B shutdown. One task to be carried out before installation and alignment of the Microscope is the location of the analyzed electron beam plane. Time needed is outlined for the several approaches to this.
Pre-installation time required
- Microscope
- Burn paper approach: 1 hour during Hall B access before shutdown
- Translation table with counter (Hovannes):
- none? will the prototype box be mounted on the translation table during installation?
- few hours during access before shutdown? will they permit equipment there during high current running going on now?
- Dead reckoning: position determined from survey - not preliminary time required.
- Active Collimator
- non-JLab PC use permitted: none
- only JLab PC allowed: 3-5 hours (readout hardware/software installation and testing)
Installation time required
- Microscope
- time in counting house to test Hall B-loaned control PC with prototype: 2-3 hours
- time in the Hall: 3-6 hours
- Active Collimator
- time in the Hall: 1-2 hours (may overlap with microscope installation)
Run time access
No special access during running is requested. All handling of equipment in the Hall will be done during regular access periods.
Equipment
Microscope prototype
- prototype chamber with control and amplifier electronics: UConn
- prototype control PC (SiPM/Amp settings, alignment control): loaned by Hall B (Sergey Boyarinov)
- trigger scintillator with dual PMT readout: HallD/GlueX (any loans from Vitaly Baturin?)
- DAQ VMS crate: HallD/GlueX Trigger/DAQ group loan (including the following)
- 250 MHz fADC
- LED+F1TDC
- ROC & Trigger processor
- NIM (?) crate: HallD/GlueX Trigger/DAQ group loan (including the following)
- level shifters
- CFD
- Cabling:
- Coax (LEMO) connectors: loaned from electronics/DAQ (F117)
- long RG-58 to accel. RF: UConn
Active Collimator
- prototype and all readout electronics: UConn
- control and DAQ computer:
- UConn pending confirmation that non-JLab PC may be used as last time.
- ??? (Windows computer needed)
Connections in Hall B
- Triggering:
- own trigger paddle used (see above)
- accel. RF connection
- Data stream
- Sergey Boyarinov suggested plugging into CLAS data stream
- own HallD/GlueX DAQ PC ???
