Private:Hall D Staff Meeting, August 27, 2012
Present: Fernando Barbosa, Daniel Bennett, Vladimir Berdnikov, Hovanes
Egiyan, Mark Ito, Manuel Lara, John Leckey, Bert Manzlak, Lubomir
Pentchev, Yi Qiang, Dmitry Romanov, Patrizia Rossi, Elton Smith
(chair), Sascha Somov, Simon Taylor, Ivan Tolstukhin, Tim Whitlatch,
Beni Zihlmann
Bert, Safety
1. Everyone should read and sign the work governance document
(SAF-116kd) using the web-based training system.
2. Friday a Hall C tech was injured while decommissioning the SOS
(recordable injury). He was a spotter inside the shield house. He
twisted his ankle. They applied ice and first aid and he was sent
to Port Warkwick for x-rays. He is currently on partial
restrictions.
Patrizia
Our new deputy associate director for experimental nuclear physics was
introduced. She will be attending Hall D meetings in the future to get
a feeling for what we are doing.
Tim
* first part of cryo platform in in the next few days
* distribution box next
* tagger magnet arrives in the fall, getting ready for its arrival
* OSP for solenoid power supply had been reviewed
+ comments from Bill Merz to be incorporated by end of week
Beni
* Package 3 moved to EEL
* HV turned on today
* first strip signals look good
* TDC only testing for now, ADC does not work
Dmitry
* preparing new release of the CCDB, SQLite used for local work
* working on the switch to the CCDB from the file-based system
* reviewing the trigger database
Sascha
* SOW with CUA written, Franz Klein and Dan Sober need to respond
* work done on the specifications for the PMTs
+ 1" tubes used by Hall B are one option
* discussion of purchasing scintillator tiles with Eljen and St.
Gobain, hope to purchase in September
* working with Dmitry on trigger database
* there are several trigger boards needed soon from Chris Cuevas's
group
Hovanes
* fiber contract for the counting house in progress
* fast beam shutdown plan needs work, will consult with Todd
Satagawa, want to protect the goniometer
* Yerevan/Hall-D MOU has gone through one iteration
+ sent to DOE for approval
+ needed before visitors from Yerevan can come here
* got 2 CAEN 1495 modules
+ programmable "NIM" logic
+ Ben will give tutorial on FPGA programming Wed. at 1:30 pm
* Counting House: all of work on power from computer floor finished
+ 120 V from ceiling to racks yet to be done, some parts needed
* meeting on the purchase of the network fibers for the run from the
communication room to the rack room haws held with ACC and CC folks
+ Bryan Hess will be asking for quotes
* bar code readers: quotes came in but funds are frozen, item for
next fiscal year
Ivan
* Had a discussion with Engineering on frame, electronics for the
pair spectrometer
+ the board will take several weeks to produce
* testing glue for the joint between scintillator and fiber
* SiPM testing: cross-talk measurements, after pulsing
characterization
Vladimir
* worked on grounding for FDC package 3, from 16 to 18 clips per cell
* conductive tape measurements:
+ counting metal balls with a microscope
+ correlating count with resistivity
Lubomir
* 3rd package complete
+ LV applied on all channels
+ all subsystems installed, including grounding
* cooling tube arrangmenent changed to push in on pre-amps
* corrosion on cathodes points to the combination of EPDM O-rings and
moisture
+ some wire planes from layers showing corrosion will be re-used
* after refurbishing the 1st package, will move on to the 4th;
waiting for more wire frames (need circuit boards to be made)
* studying use of conductive tape
+ not an aging issue
+ change in resistivity likely due to handling
* Bill Crahen made tools for maintaining cathode flatness
Simon
* working on alignment procedure using straight tracks
* improved vertex algorithm for multiple tracks
* work on other general debugging issues
* will investigate memory footprint problem reported at data
challenge meeting
Mark
* working on Data Challenge
* helping Dmitry with CCDB
* working on FSU contract
* working on FIU contract
Dan and Manuel
* working on controls for CW bases for FCAL
+ boot loader: can program all bases over CANbus
+ developing power chassis control software
Yi
* working on monitoring system for solenoid
* EPICS interface developed
* can reach maximum DAQ speed on ADCs on all 32 channels
* save local snapshot of values
* studying stability issues
Elliott
* Ben Raydo's talk on Wed. on FPGA
* inventory database usable
+ Josh putting stuff in
* Dave Abbott working on raw data tapes
* working on translation in JANA
* solenoid test going well
+ Josh produced test plan
* FMEA done, can use material for task hazard analysis
* cryo canon schedule
* vacuum doing well
* PLC programming going well
John
* working with IU folks on plan for darkroom and cabling for FCAL;
will be reviewed by Tim and Fernanado
* design for darkroom progressing
* frame for FCAL arrives mid-October
* 13 month schedule developed, starts at frame arrival
Fernando
* flash 125
+ tested with dual edge transfer
+ Cody Dickover implementing the full-fledged interface
firmware, starting from a version from Ed Jastrzembski
+ there is a time-out problem, origin unclear
* flash 250
+ in production
+ 1 month awa from 1st delivery to UMass
+ readiness review scheduled for September 17
* f1tdc
+ both v2 and v3 operational
+ procurement is in progress
* CAEN TDCs: receiving them in a month
* BCAL read-out boards
+ working on production protocols
+ testing starting
+ ready for procurement soon
* Start counter read-out boards at FIU, they look good
* pair spectrometer read-out boards, will be in hand on Oct.
* cabling and installation meeting
+ some cable maps missing
+ need to coordinate schedules of various groups
+ received many cables, being tested
