Private:Hall D Staff Meeting, September 23, 2013
Present: Fernando Barbosa, Vladimir Berdnikov, Eugene Chudakov (chair),
Mark Dalton, Hovanes Egiyan, Nerses Gevorgyan, Mark Ito, Vanik Kakoyan,
David Lawrence, Lubomir Pentchev, Sergey Pozdniakov, Elton Smith, Simon
Taylor, Ivan Tolstukhin, Alam Toro, Tim Whitlatch, Beni Zihlmann
Chair called meeting to order at 3:00 pm.
Announcements, Eugene
* no word on lab budget vis-a-vis a government shutdown
* for Physics in FY14, not an optimistic outlook; can continue for
about 2 mos. on current plan at CR levels
* FEL group has dissolved, no Navy funding, Lab trying to retain
staff, personnel offered to Hall D
* Re-baseline still not finished
* magnet review
+ panel will meet Fri., Bob McKeown chair, several experts on
panel, will look at Hall D and Hall C magnets
+ Leigh Harwood suspects turn-to-turn short, short would work
against ramp direction, possible heat source, perhaps 1 W
o we should then see it in voltage on sub-coil
+ have observed small spikes, about 20 mV, for 10 ms, all coils
o Yi is analyzing data
o a single spike should not cause a quench
+ "flux jumping" also proposed as possible quench initiator
+ in December there will be a Director's Review, DOE review to
follow in early 2014
* plans going ahead on injector test area, one RF cryomodule
+ current may be too high for detector testing
+ ideas solicited for use by Physics
Installation, Tim
* BCAL installation tooling being removed, upstream platform going
in, should take about two weeks
* chilled water being installed, no AC this week
* tagger magnet mapping fixtures tested for fit
+ Giles will bring in mapping equipment
* Elton concerned about humidity in the Hall and its effect on BCAL
electronics, a nitrogen purge may be in order
* BCAL cooling manifold came in last week
* cut holes for upstream platform cable runs
* installing rest of cable trays for BCAL
* Danfysik came and looked at pair spectrometer magnet power supply
+ some mechanical adjustments made
+ electrical testing: OK
+ discussed solenoid PS plans as well, they will return in
December for other work in Hall C and discussion can continue
* Electrical power transformers are all installed, panels are almost
all done
+ will get help with power cable runs from Accelerator and
Charles Hightower
* gas shed, alcohol refrigerator plumbed, Scot Spiegel working on it
+ big main panel due Set. 30
* linear stages for pair converter and amorphous radiator came in
Electronics, Fernando
* getting three folks from FEL to help with installation, 1 engineer,
2 physicists
* putting together an installation crew roster
+ some will need training to work in Hall
+ plan to start cabling in two weeks
+ may still need more personnel
* starting to move crates from F112 to Hall
+ full crate tests nearly done except for F125
+ as tests complete, crates can be installed in Hall
+ next are the 2 BCAL areas, then U1, then U2
* Alan is working on LED pulser system and the master oscillator from
Accelerator
* for the pair spectrometer, half of the electronics are ready
* for the start counter, electronics is almost done
+ Nick Sandoval will travel to FIU to set-up read-out chain
there
* F250
+ of the 350 ordered all in in hand save 16, those did not pass
tests
+ Bryan Moffit will take over the test setup
IT Steering Committee Meeting, Mark
* MIS: Kari Heffner
* Operations: Andy Kowalski
+ report on network outages
+ emergency communications: cell phone signal boosters will be
deployed
+ Facilities Management devices will be put on on segmented
network
+ cyber security major threats
o 3rd party software
o phishing
o visiting external web sites
+ redundant 10 Gbps connection to ESNet now
+ virtual desktop infrastructure (VDI) to come: local client
accesses virtual windows machine
* SciComp: Chip Watson
+ 12 GeV Review Nov. 25, 26
o 18 month period between reviews
+ new farm nodes (35% increase), 24 nodes, 16 cores per node, 2
thread per core
+ added 50 TB server (25% increase)
+ one more frame added to tape library with 2 LTO-6 drives
+ data management plan: Graham Heyes
o DOE mandated
o tiered system: JLab, Halls, individual experiments
Pion Polarization Workshop, Elton
* workshop is Friday afternoon
* 3 theory talks
1. Barbara Pasquini: pion polarizability
2. Jose Goity: chiral perturbation theory
3. Michael Ramsey-Musolf: implications for g-2
* experimental discussions
+ muon detector behind FCAL
+ simulations
+ running tagger at 6 GeV
+ nuclear target
Calorimeters, Elton
* BCAL installed in magnet
+ some read-out modules removed and inspected, looked good,
re-installed
* FCAL completely cables up
FDC, Lubomir
* Tim: Richard Getz has drawn up position of FDC during cabling both
near magnet and at a position 5 feet back
+ will be close to BCAL, but should not interfere; there should
be room to test both
* using spare package as a test bed for F1-TDCs
* thick cell tests
+ needed higher voltage in the EEL than was needed at Blue Crab
+ found gain and other characteristics depend on gas flow rate,
could be some outgasing from internal chamber surfaces causing
recombination
Online/DAQ, Hovanes
* will do network install in Oct. and Nov.
+ fiber panel in wrong place, must be moved
+ need to install switches, fibers to switches, switches to
counting house
+ location and number of switches to be determined, depends on
rates from crates
* Facilities has declared the counting house complete, but there are
still some punch list items (fire extinguisher, SWIS computers)
* AC will be down in counting house for two days at least, coordinate
with online group if you need your computer and/or crate turned on
Other Items
* tomorrow at 4 pm, Elton will give a practice talk for his
presentation at MENU
* David is one volunteer short for guides for the DNP tours of Hall
D, contact David if you can help
Adjourned at 4:05 pm.
