Eugene
* Sequestration crisis passed for now. No shortened work week will be
necessary.
* We are now recording progress on two schedules, old and
re-baseline.
+ Will discuss adoption of re-baseline August 9.
+ For us the main issue is the solenoid.
+ If approved, will be redefined again at end of Aug.
+ Put into effect in Sep.
+ We may be able to shift resources among Hall D activities
during final exercise.
* Many activities running over projected costs. Solenoid, detectors,
beamline
+ will need to understand this during remaining part of month
* Medium energy review conducted at DOE headquarters
+ They looked a accomplishments on the Physics research side
+ Rolf Ent, Patrizia Rossi, Doug Higinbotham, Roger Carlini gave
presentations
+ all labs and university groups made presentations
+ went well for the Lab
* Software review will be sometime in the Fall
* Next Lehman review in Dec. or Jan.
Tim, Solenoid
* getting ready to power at high current
+ by end of this week want to start cool-down
+ power supply write-ups need to be done
+ results of 140 A test nearly signed off
+ waiting for refrigerator to get cleaned up
* power supply is working
+ no more voltage spikes during slow ramp up
* Danfysik will be sending hardware and schematics by Tue. to tune
the power supply for high current
Bert, Training
* Pressure vessel awareness training will be held June 26
* an update for those who have already had the training, especially
if it was more than three years ago
* those in doubt are encouraged to take it
* applicable codes, relevant design authorities, expectations for
operators will be covered
* some in each Hall group should receive training
* Tim mentioned vacuum systems in the Hall: solenoid helium and
nitrogen circuits and vacuum, beamline vacuum, FDC gas and cooling,
BCAL cooling system, target, shop air and nitrogen, chilled water
system
* operators have to know about restrictions, changes have to be
properly approved and documented
David
* was at Conference in Italy last week
+ talk went well
+ Drew Weisenberger gave a good talk too
* worked a lot on Geant4 simulations for charged pion polarizability
proposal
* will turn back to work on translation tables next
* Rory will not be giving another practice talk, his dry-run today
went well
Hovanes
* servers and furniture have arrived at the counting house
+ furniture is mostly installed
+ Paul Letta will install computers
+ at beginning of July we should have counting house ready for
occupation
+ one chair was borrowed by Facilities
* servers for event builder, level 3 farm, raid disk, infiniband
networking equipment will be part of HPC purchase
+ we should have them by the end of the fiscal year
* EPICS: working on setting up alarm system
+ part of CSS, needs to be compiled for our use, e. g., HV
Nerses
* Working on CAEN HV driver for the CDC
+ getting info from Fernando's spreadsheet using David's scripts
+ making channels with logical names
+ CDC has the messiest scheme; if we do this the rest will be
easy
Sergey P.
* working on inventory database application for us
+ using the Hall B system
+ info on electronics and other equipment
+ now writing script to extract info from Fernando's
spreadsheets
+ there has been some discussion of database schema, B's needs
vis-a-vis those of D
Sascha
* Sascha working with Liping's students on the low-granularity pair
spectrometer hodoscope
+ set-up with LEDs to check PMTs
+ making plots to go on the wiki

+ Anatoly almost done with 110 one mm tiles, re-doing a few
+ started on 2 mm tiles
+ info going into Excel
+ Ursula helping Anatoly and working with Giles on Labview for
magnet mapping
* PCBs for fixed array arrived, waiting for dividers, hopefully they
will arrive this week
+ all tubes at JLab

FCAL
+ Liping gave a dry run last Friday
Mark

cost, just materials

website
* UGBoD term ended
Elliott
* Online meeting Wednesday
+ hear about experience with C++11
+ conditions database

* working hardware modification for solenoid dial gain and balance
display
* PLC quench detector almost done
* fast dump signal from Cryo group, an early warning
+ Jonathan Creel's idea, wires already there
* PLC test stand moved to counting house
* Hovanes: what is plan magnet control division of responsibilities
between cryo and us with respect to magnet control?
+ has to be worked out, they supply cryogens, we control the
magnet
Simon
* adding cooling manifolds o simulation
* working on FDC and CDC stub matching, comments, some bug fixes
* helping Liping prepare for PAC presentation
* Eugene: any more news on lower field running?
+ some improvement in efficiency, not much in the over-all
number
Beni
* Got RS-485 communications for the FDC chiller going
* with Cody and Bryan Moffit read 2 VXS crates with 12 FADC-125s
each, and with TI, TD boards
+ reading in raw mode, 100 sample window, gives 1.2 GB in about
10 minutes
+ trigger rate is 30 Hz with cosmics, read-out rate limited to
10 Hz
+ 12 ADCs cover strips for 4 planes
+ there are some missing strips
+ debugging ROC-based sparsification now
+ need a new VXS crate, old one does not have extra slot for the
TI
+ see power supply oscillation, running at 100 A
+ using old SSP firmware for now
+ Sascha: algorithm on FADC?
o Fernando: different pulse shape than for PMT, Naomi
working on it
o Beni: there exists algorithm with 5 points interpolated
between samples
Tim, Engineering
* the engineering staff have moved from the ARC to the TEDF
* tagger magnet is pumped down and is leak-free
+ tagger window is next, 1/4 mm aluminum
* drawings on the mapper fixtures done
* power supply may not need refurbishment
* the test supply is sitting in the ESB and can act as a spare
* pair spectrometer hodoscope support frame out for fabrication i a
week or two
* fixtures for pair spectrometer magnet mapping being worked on
+ Giles and Ursula are working on the software for mapping
+ Controller and motor from FDC being used
+ power supply due in mid-Aug.
* Bert: safety wardens for physics division areas
+ TEDF: Joyce Miller and Marti Bennett
+ ARC: Brian Cross
+ Test Lab, high bay of TEDF: Doug Higinbotham
Lubomir
* Test with full electronics on third package
+ one week with HV on, stable, no gas leaks
+ LV on for 4-5 days
+ all pre-amps attached, wires and strips
+ water chiller working, some leaks fixed by Bill
+ connected 4 cells with signal cables, need another crate to do
2 more cells
+ testing being done in EEL 126
* Spare package
* issue with gas leak fixed
+ 2 cells added to previous 2, tested, OK
+ 2 more added last week, testing started, 1 cell OK so far
* Flourinert chiller consumes a lot of power
+ many chiller jokes told at this point
Elton
* Gave three lectures at HUGS last week
* All work on re-gluing BCAL light guides done
+ those with problems fixed
+ those without problems re-illuminated to ensure complete
curing
* crew working on sanding light guide making covers, making cooling
plates
* now have complete inventory of non-conforming light guides
* need to notify Santa Mari about needed replacements
* 110 light guides already shipped back for replacement
+ 84 replacements about to be shipped
* tomorrow will start on "new" modules
Fernando
* fixed array: Vladimir Popov will have PR ready to go in the first
part of July
* the microscope electronic are under review, UConn corrects some
problems
+ should have PO issued this week
* start counter: all parts are here, SiPM's as well
* pair spectrometer a bit behind, should be coming up in 2 or 3 weeks
* had meeting with Tim on cabling, another one on Wed.
* working with 6 students
+ 4 on cabling
+ 2 on BCAL read-out
* next week ready for installation of BCAL cables
* BCAL read-out boards 50% done
* Elton: FCAL dark box
+ John Frye was here last week
+ most of material for dark box here
* TDCs from UMass testing effort should be here next week
* Flash-125 should all be here by end of month
Eugene
* Blue Crab clean room may be moved to Lab. May have space in new
building
* Sergey Kuleshov is here visiting
* Magnet quench causes:
1. movement of coils
2. conductor portion in wrong part of physical parameter space:,
pressure, temperature, magnetic field
+ We may have stressed magnet more than SLAC
+ quench conditions: 4.6 K, 1460 A, 3 T
+ Rolf will allow 1350 A, but not a lot of margin at 4.5 K
+ would prefer lower temp by 0.2 or 0.3 K, but that would
require a new refrigerator, about 1 M$
* David: what about attending DNP in Newport News
+ Eugene will look into this
* Elton: when is re-baselining tweaking due?
+ Eugene: before next progress report, i. e., by the end of the
week
