Private:Hall D Staff Meeting, December 2, 2013
Present: Eugene Chudakov (chair), Mark Dalton, Hovanes Egiyan, Mark
Ito, Vanik Kakoyan, David Lawrence, Lubomir Pentchev, Sergey
Pozdniakov, Yi Qiang, Dmitry Romanov, Patrizia Rossi, Elton Smith,
Sascha Somov, Simon Taylor, Ivan Tolstukhin, Tim Whitlatch, Elliott
Wolin, Glenn Young
ENP Issues, Patrizia
* Hall D tagger magnet mapping review tomorrow
+ 2 hours
+ review division of labor between ACC and ENP
+ does not cover magnet operation with beam
Software Review, Mark
* Round 2: 1st time 18 months ago
* Convened by Bob McKeown
* Committee:
+ Torre Wenaus (BNL/ATLAS) - Committee Chair
+ Elizabeth Sexton (FNAL/CMS)
+ Sergei Gerassimov (CERN)
+ Martin Purschke (BNL/PHENIX)
+ David Nathan Brown (LBL/BaBar)
* talks:
+ Curtis, overview
+ Mark, computing plan, data challenges
+ David, improvements in reconstruction
+ Justin, analysis workshop: event generators, analysis tools,
event classification (BDT), amplitude analysis with AmpTools
* written material:
+ GlueX Computing document, updated from last time
+ Appendices:
o data management plan, Lab and Hall D
o draft analysis plan
o workflow system requirements
* Committee report summary:
+ cited excellent progress for all Halls during the past 18
months and thought we are on track for data taking
+ For the 12 GeV program as a whole
o they noted the use of parallel processing schemes,
o encouraged more use of static and dynamic code profiling.
o They asked that we consider doing code review for crucial
new developments.
o They also liked that software workshops that have been
held, noting that recording of the sessions is valuable
for reaching a larger audience.
+ For Hall D
o they noted the data challenges we have performed,
o the fact that the data from DC I was used to support the
PAC 40 proposal.
o They also mentioned the inclusion of QA and data
challenge management in our software manpower plan
o applauded the appointment of a Calibration Coordinator.
+ Report:
o An interim report will be made available to Lab
management soon
o the Committee hopes to issue its final report before the
end of the year.
* Personal Comments:
+ we were the only data challenges
+ probably the most comprehensive written material
+ no push back on using JLab-specific tools for JLab farm
workflow
+ suggestions on tools: no SRM for data transfer, no LFC file
catalog
+ updating tools: can get up-to-date advice, take advantages of
recent developments
+ lot of time spent talking about computer center issues
+ overall, easy on us
Engineering, Tim
* all racks installed in the Hall
* all cable trays save one installed
* N2 system tested and working
* chilled water system tested and working
* dry air system for the CDC designed, some parts in, installation
start this week
* TOF, hope to get frame in next week so we can start assembly
* mapping for tagger magnet can start soon after tomorrows review
* FDC racks, wires pulled, not live yet
* electricians moving to BCAL north tomorrow
* dirty power: some left to do
CDC installation, Lubomir
* before Thanksgiving, mesh installed, bearings adjusted
* several LV cables installed on detector side by Vlad
* need to disconnect some of these cables from the mesh
+ cannot easily pull on the system, push is ok
+ want to find what the problem is
* cooling system read to hook up, need that before powering detector
* for the CDC: FEL person testing HV, connecting boards
Calorimeters, Elton
* monitoring system installation continues
+ boards Alam built: box just ordered
* on FCAL installed except for patch panels
+ all cable connections ordered
* the VME crate for controls installed soon
* FCAL will be closed any day now
+ needs fire safety review before HV applied
+ will have stand-alone fire suppression system
Beamline, Sascha
* tagger microscope construction
+ 1st bundle fabricates, will be tested
+ working on fibers for the next bundle
+ can go at 2 bundles per week
+ pre-amp boards: isolated soldering problems being worked on
Pair Spectrometer, Ivan
* received all parts
* can now assemble whole detector, starting this week
* Chris finished one arm, measured all 28 channels with laser in dark
box
+ gain (except for one channel) within about 1% of each other
* this week, second arm of electronics will be ready
+ will test next week
* need two weeks to stack tiles, waiting for hardware screws, pins
+ Chuck ordered them last Friday
* p. e. peaks look good, results on wiki page
Diamond Procurement, Sascha
* got in touch with Element 6
+ we might be able to purchase diamonds, test them at CHESS, and
select the good ones
+ would need to provide measurement results to E6.
+ 500 micron thick, 4.6x4.6 mm, 200 pounds each
Goniometer, Yi
* gave report at last beamline meeting
+ satisfies our specs
+ precision of individual steps, .2 mdegree spec, see .1 mdegree
yaw, .2 pitch measured
+ repeatability, no spec, but see 1 mdegree
Solenoid, Elliott
* George and Elliott meeting with one person a week, assessing
progress
* 15 or 20 man-weeks of work left to do
* about 50 items on list, prioritized
* flow control on vapor-cooled leads abandoned, will set to max. flow
with some margin
* Work being done Mark, Scott, Giles, Dave, not a high priority task
for them
Schedule of Cryoplant, Glenn
* focus on CHL until solve the linac balancing problem
* Data will speak at review next week
* Director's monthly review: June suggested target
Short Sample Test, Eugene
* Procurement on short sample test in Holland was on hold, has been
revived
+ need to wind on a cylinder, tooling needed
+ test plan already written
Time-of-Flight, Mark
* all TOF modules delivered, also support frame components machined
by FSU have been delivered
* discussions held on how and when to close out FSU contract
* group reviewed TOF assembly procedure
Start Counter, Mark
* no new news from FIU, last known status: scintillator ordered,
scint. test stand done, working on assembly stand
* prototype inner mandrill made, Tom working on proving scheme for
carbon fiber support
FCAL Read-Out Sascha

CODA 3, Mark
* working toward testing 6 crate read-out, 1 crate working now
+ data looks ok, getting warnings on timing
+ working through bugs in system components (ET system,
configuration editor)
+ good response from CODA group on problems
* working on auto-startup scripts, hard part finding all the things
that need to be killed

* working with Vanik on microscope support structure
+ need to move three motors in coordinated fashion
+ want to lock out motor control when in final position
* microscope voltage control
+ development based on API agreed to with Richard
* need to start development for scalers in FADC for monitoring FCAL
+ software exists
o Sascha: Roman wrote the system, uses shared memory
Active Collimator, Sascha
* activity code given to ACC a long time ago
+ VME crate, ADCs: some ordering done
Online, Elliott
* computers, accounts, directory policy written
* online data challenge
+ original plan mid-Dec.
+ now plan will do a bigger one in late Spring
* hoping to get rest of servers in counting house going soon
* Eugene: need well-defined milestones for CODA group
* install of fibers for networking: in FM now, will be bid out
+ talking with Tom
+ fibers will run directly from Counting House to individual
crates
+ no patch panels
+ interim network working
Offline, Mark
* bggen added to nightly builds
* some extensions to CCDB discussed with Dmitry
* gave Graham a version of our data management plan
Databases, Dmitry
* version 0.9 ready to go
+ database connection time-out feature added
* working with Sascha on the trigger database
Tracking, Simon
* alignment of CDC wires with cosmics
+ put in offsets artificially, reproduced them in the
measurements
+ some problem ares still
Configuration Management Plan, Elton
* we are required to participate
* we need to list critical specs for each detector system
New Staff Member Announcement, Eugene
* Sergey will come in January
Target, Mark
* the target will be super-cooled
+ there had been a plan to operate on the vapor pressure curve
to reduce hydrogen volume
+ increased volume of hydrogen in the Hall needs approval by
