Meeting

  2. FLYSUB: Tracking and PID detector R&D for EIC with GEM Shift Crew 1 • FLYSUB Consortium is: • Brookhaven National Lab (BNL) • Florida Tech (FIT) • Stony Brook University (SBU) • University of Virginia (UVa) • Yale University Shift Crew 2 T-1037 is funded by the Site-neutral R&D Program administered @ BNL FLYSUB Team for the T-1037 Test beam @ FTBF Fermilab(October 2013) RD51 Coll. Meeting

  3. Electron-Ion Collider • The Next QCD Frontier • Physics: • Matter at high gluon density • Nucleon spin • Spatial Parton Distributions • eRHIC @ BNL • MEIC @ J-Lab RD51 Coll. Meeting

  4. Mini drift GEM detector : Brookhaven National Laboratory Mini drift GEM setup (MT6 1A @ FTBF, Oct 2013) Challenge: Standard GEM tracking chambers have their resolution deteriorate with non-normal incidence. Approach: Raising the grid above the first GEM allows each chamber to measure a vector to correct for the inclination of every track. RD51 Coll. Meeting

  5. GEM with 3-Coordinate Readout : Yale University 3D-Coordinate GEM setup (MT6 2A @ FTBF Oct. 2013) Challenge: Cartesian Readouts lead to ambiguities in X-Y associations for high multiplicity events. Approach: 3 coordinate readout made on double-sided Kapton. New 3-coordinate readout-Hit matching: GEOMETRY & CHARGE Standard COMPASS style Readout - XY Hit Matching by Charge RD51 Coll. Meeting

  6. Large Area GEM Tracking Detector: Univ. of Virginia & Florida Tech Zigzag readout for CMS chamber Large size GEM setup with 10 chambers (MT6 2B @ FTBF, Oct. 2013) FIT S4 zz FIT CMS zz FIT 10x10 zz 2D stereo angle readout Uva EIC GEM prototype UVa SBS1 UVa EIC Tracker 1 Tracker 2 Tracker 3 UVa SBS2 Tracker 4 Challenge: GEM detector size must be expanded with excellent spatial resolution Approach: Florida Tech: CMS-like GEMs with zigzag readout, low numbers of electronics channels Univ. Of Virginia: Standard 2D Triple GEM with u/v readout and low material budget RD51 Coll. Meeting

  7. 2D GEM-based Short Radiator RICH: Stony Brook University GEM-RICH setup (MT6 2B @ FTBF. Oct. 2013) Challenge: Hadron (pion, kaon, proton) ID at high lab momentum requires the Cherenkov effect. Typical long radiator lengths (e.g. 3 meters CF4 in LHCb) make experiments large/costly. Approach: CsIphotocathode RICH allows operation in DEEP UV (down to 120 nm) thereby collecting more light. Further, this photon detection technology is VERY inexpensive per unit area. RD51 Coll. Meeting

  10. RCDAQ in a few lines... • Lightweight and versatile DAQ system which can read out the SRS system (among many other things) • RCDAQ is available to RD51 members • FermiLab MWPC system implemented in RCDAQ in September • Convenient operations, monitoring, and analysis • Ext. parameter logging and automated bookkeeping a particular strength • Workhorse DAQ for BNL, SBU, and Yale's detectors • See the SBU RD51 meeting for an in-depth discussion: https://indico.cern.ch/contributionDisplay.py?contribId=54&sessionId=7&confId=179611 RD51 Coll. Meeting

  11. Taking it all the way: The Mini drift GEM Readout • Reading the SRS is easy, done deal. • We were rotating the detector in the beam with a remote-controlled step motor • Ideally, the raw data files would contain the read-back motor position; we also took a webcam picture of a scale at the rotating axis Read back and capture the SRS setup parameters This is the setup for the begin-run event (type 9): rcdaq_clientcreate_devicedevice_command 9 0 "srs_controlreadapv > $HOME/apv.txt" rcdaq_clientcreate_devicedevice_file 9 910 $HOME/apv.txt rcdaq_clientcreate_devicedevice_command 9 0 "/home/eic/rcdaq_setup/prepare_run.sh" rcdaq_clientcreate_devicedevice_file 9 940 $HOME/current_position.txt rcdaq_clientcreate_devicedevice_file 9 941 $HOME/snapshot.jpg rcdaq_clientcreate_devicedevice_file 9 942 $HOME/overhead_snapshot.jpg Script reaches out to the motor control system, gets readback, gets two cam pictures. Executed each time a DAQ run starts Text file w/ position and two jpegs included in the begin-run event RD51 Coll. Meeting

  12.

  16. Safety Issues raised by ORC Team @ Fermilab Comments on the SRS mini crate in MT6 1A (Mini drift GEM stand ) 1) The CERN VME crate's safety ground connection is now OK. However, upon inspection of a similar crate, it was found that there are some poor wiring techniques used in the construction of the crate. These techniques are not severe enough to warrant pulling the installed crate out of the installation but remedial action (to be described in an upcoming memo) should be taken at the earliest convenience. The crate is OK to use for this installation at this time. Comment on the mini crate @ MT6 2A (GEM-RICH stand) The VME CERN crate used, upon examination had a loose AC-DC supply inside the crate and its AC cord intermingled with the DC output wires. Since this crate is out and open, require that the small power supply be restrained and the AC cord loops be separated from the DC cables. On the Euro-crate @ MT6 2A (3-D coordinate stand) The SRS crate and module readout system, made by CERN, is used here. The crate chassis is of a different configuration (larger with a dual power supply) than the one previewed yesterday. However, the construction is similar and presents the similar concerns as the smaller crate. These concerns will be addressed to CERN and are now, for this installation, permitted to be used just for the term of this installation. On the SRU and the Euro-crate @ MT6 2B (Large size GEM stand) A custom-built (by CERN) data switch chassis is connected to the CERN SRS crate power cable. There can be a maximum of 15 Amps on the 3V supply wire. However, the module (load side) has no observable fuse protection. Also, no documentation on this chassis was available at the time of the review. This issue, along with the crate's issues, will be taken up with CERN. Another concern with the CERN equipment is their use of DC power over the HDMI connectors. The power source is current-limited but the current protection is provided by devices NOT designed for overcurrent protection. In their SRS statement, the use of small resistors and a "small" wire soldered in between pads is described as sufficient current protection. This is NOT a sound practice and current protection should be provided by proper current protection devises, fuses, resettable fuses, CBs, etc. Again, an issue to be taken up with CERN. Given that the marginal operational and fuse protection issues discovered with the CERN crate and the data switch chassis, a camera should be set up to monitor these pieces of equipment during operation. Therefore, close inspection when preparing this installation for operation and remote monitoring of the installation needs to be exercised when operating this equipment. RD51 Coll. Meeting
