10/15/2013RD51 Coll. Meeting4 Mini drift GEM detector : Brookhaven National Laboratory  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.

10/15/2013RD51 Coll. Meeting7 2D GEM-based Short Radiator RICH: Stony Brook University Challenge: Hadron (pion, kaon, proton) ID at high lab momentum requires the Cherenkov effect. Typical long radiator lengths (e.g. 3 meters CF 4 in LHCb) make experiments large/costly. Approach: CsI photocathode 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. GEM-RICH setup (MT6 FTBF. Oct. 2013)

10/15/2013RD51 Coll. Meeting16 Safety Issues raised by ORC Fermilab 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. On the SRU and the MT6 2B (Large size GEM 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 MT6 2A (3-D coordinate 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. Comments on the SRS mini crate in MT6 1A (Mini drift GEM 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. Comment on the mini MT6 2A (GEM-RICH stand)
