Private:Hall D Staff Meeting, October 22, 2012

Present: Dan Bennett, Vladimir Berdnikov, Eugene Chudakov (chair),
Hovanes Egiyan, Mark Ito, David Lawrence, John Leckey, Bert Manzlak,
Lubomir Pentchev, Yi Qiang, Dmitry Romanov, Sascha Somov, Simon Taylor,
Ivan Tolstukhin, Tim Whitlatch, Elliott Wolin, Glenn Young

Eugene, Announcements

* enhanced security situation persists, not known for how long
* Lab got a budget based on a continuing resolution
+ both 12 GeV and operations
+ we are encouraged to go ahead with procurements
* MOUs and visitors
+ Physics decided no DOE approval
+ 12 GeV will require MOU with the institution of visitors
* DOE is scrutinizing travel
+ limit on DOE spending per conference, across all DOE labs
+ if for a big conference, submit request well in advance,
especially foreign travel
* ETC: estimate of funds still needed to finish, every year a big
change request
+ need to work on this now
+ cap at 1,2 $M of increase this year, 2 M$ last year
* PAC report came out
+ we reviewing the report on the rare eta decay proposals
+ comments mainly on time-line and budget
* Hall D approached by people from Panda/Juelich
+ Elton will give a talk at their collaboration meeting
+ perhaps a source of new collaborators
+ rare eta decay interest
+ Panda struggling with where to get lead tungstate crystals

Bert, Safety

1. last week we were briefed by Mary Logue on first part of thr LSD
+ report all work related illnesses or injuries, even first aid
+ phone call to Medical Services is OK
2. work control documents
+ for work in experimental halls, EEL, Test Lab. storage
buildings: work control document should be posted
3. students need to get training and guidance
+ they should understand concerns and mitigation techniques
4. if working in the Hall, check in with Tom Carstens, the work
coordinator
+ Tom has daily work plan
+ let him know so he can plan
5. reminder: in experimental halls, you need to be trained on work
governance, SAF116kd
+ good for all halls during shutdown

Tim, Engineering

* lately, a big push on solenoid
+ good progress over last 2 weeks
+ items: cryo-can, power, cabling, more to go
+ started making connections from can to chimneys
* gantry has been awarded, due Dec. 16
+ if magnet delivered before then, might have to store in Hall,
or ask them to hold it
* vacuum chamber for tagger: end of Nov.

Lubomir, FDC

* Anatoly Sitnikov and Dave Butler are working at Blue Crab still
+ Anatoly is refurbishing old frames
+ Dave working on wire deadening
* package 1 is ready, waiting for gas
* soon will have parts for package 4
* corrosion tests are going slowly
+ another sample failed over weekend
* good results from EEL 126 and Beni Zihlmann on package 3
+ 3 cells done, all cathodes, fixes done by Vlad
+ continuing with 4th cell
* room 126 EEL hot and humid
+ solutions being discussed
+ Facilities request to be made requesting a proposal from them
+ several solutions on the table
+ will remove package 3 as soon as testing done

Eugene, Calorimeter

* all procurements for electronics are out
+ one was returned
* PR for mechanical parts have not been written

David

* working on raw data format with Elliott
* working on simulation for charged pion polarizability
+ exploring use of vertex constraint
* working on system for converting HDDM to ROOT format

Yi

* PXI system progressing
* SiPMs: Ivan testing rest of SiPM samples
* installing A/C system in dark box in EEL: 12,000 BTU
* working on proposal for DOE program
+ Marcel from Argonne will contribute micro-channel plate
+ Sergey Kuleshov interested
+ ASU looking into a domestic vendor for aerogel

Ivan

* SiPM testing: finished 80 samples for mini-BCAL
* received SiPMs from USM, 6 had not been tested
* sorting and arranging into wedges will be done by John McKisson
+ will have a procedure to replace damaged one with one with
correct gain

Elliott

* raw data
+ one event per block
+ block mode reading has to be written,
+ compressed mode to be written, about factor of 2
+ runs at 5 Hz
+ uses translation table
* funny things in tagger simulation
* Dan gave overview of FCAL control system
+ negotiating on final requirements
* EPICS archiver: Accelerator not interested in doing CSS conversion
* solenoid cool-down commissioning review set for Nov. 6

Dan

* working on firmware for bases and power chassis
+ can talk on CAN bus now

Simon

* continue to work on alignment with straight line fitting
* reconstructing track segment from EEL package, wires only for now
* putting in fix to CDC geometry
+ inconsistency between MC and what was built
* Bill Crahen gave dimensions for survey targets, going into
simulation
* looking at e^+e^− pairs for rare eta decay

Sascha

* Dan Sober and Richard Jones are finalizing fixed array
+ produced trajectories for Dan, previously he used a uniform
field
* contract preparation for CUA almost done, collecting signatures for
SOW
* microscope construction constract: all documents received from
Richard
+ need proposal review
* pair spectrometer of mounting plate
+ submitted drawings to Fernando, he will design mounting plate
+ ordered everything
* procurement of goniometer: PR submitted
* trigger: two crates ready, working on commissioning them,
developing debugging tools and algorithm
* rare decay meetings are proceeding

Eugene, Electronics

* Flash-250s: 410 delivered to UMass, 210 of them are ours

Mark

* UMass readiness review report filed
+ most recommendations already addressed
* FIU contract: SOW, sole source written
* data challenge almost ready to go, using new nodes at JLab

Hovanes

* counting house
+ main network switch installed
+ wdiscussing switch configuration with Bryan Hess
* big printer in Hall, to be used for solonoid commissioning for now
* big UPS has been turned on, Leibert people have been working on it
+ power distribution panel not ready to go
+ never installed 120 V from ceiling
+ if UPS on, 120 V for sockets at bottom of racks
* configuing IOC for solenoid test
+ controls done through PLC
+ old EPICS to PLC interface, not flexible
+ new: Josh Ballard expresses program in XML
+ Hovanes wrote script to find elements and variables, and
generate an EPICS database
+ this time Cryo Group will not use PLCs, will use EPICS screen
* archiving, CSS a no go with ACC
* working on PXI interface with Yi
* damaged controller: they think we broke it and we did
* working on the ETC, online items

Dmitry

* created version 0.5 of CCDB: to be used for testing and deployment
+ includes interface for selecting versions at run-time
* bundled libraries for trigger database for Sascha

John

* working on beam test data analysis
+ resolution better than Radphi due to addition of optical
coockie
+ tracking systematic error now, improvement possible
+ data collected at 5.5% of 5.5 GeV or 250 MeV, down to 100 MeV
* working on FCAL darkroom
+ preliminary design sent to Tim

Bert, Mont visit

* Mont toured Blue Crab
* overview of activities given by Eugene
