2 EMR Design: Reminder Horizontal View Characteristics 24 modules (X-Y planes) 48 planes 59 bars per plane 2832 bars 3m WLS fibers per bar 8.5 km WLS fibers single and 64-channel PMTs per plane channels R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

3 New Modules Production and Assembly New Modules Patch-Pannle and Inner Cabling 2 new modules are completed 2 other modules are on the test bench a separate test of WLS fibers and PMT connectors (polishing) has been designed R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

4 New Modules Patch-Pannle and Inner Cabling Will be set up next week. R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

5 New Modules Patch-Pannle and Inner Cabling Machine Polishing. Broken fibers are clearly visible Fibers with reduced light transmition also also present R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

6 New Modules Patch-Pannle and Inner Cabling Hand Polishing Machine polishing significantly improves the quality of the surface (compare with pictures on the previos slide) R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

7 Patch-Pannle and Inner Cabling New Modules Patch-Pannle and Inner Cabling All the cables have been modeled in order to estimate their length inside the EMR box When EMR is in vertical position patch-panels will be on the top. Extra cable length is reserved for easy access to the patch-panels. R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

8 Lower Chassis Production and Assembly Lower Chassis Finite Element Analysis (FEA) EMR Rack and Outer Cabling The disign of the lower chassis has been finilized R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

9 Finite Element Analysis (FEA) Lower Chassis Finite Element Analysis (FEA) EMR Rack and Outer Cabling According to FEA the safety margin is quite sufficient. R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

10 EMR Rack and Outer Cabling Lower Chassis Finite Element Analysis (FEA) EMR Rack and Outer Cabling from VME to Control Room: 10 BNC + 1 optical fiber from EMR to the VME crate June 2011: 12 x SHV 4 x SMA 8 x BNC 3 x LV 4 x 17-twisted-pair December 2011: 96 x SHV 32 x SMA 50 x BNC 5 LV 4 x 17-twisted-pair R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

11 Firmware and Data Format Firmware and Data Format Power Supply for FEB+DBB Communication scheme for the readout of the DBB has been defined. Firmware for DBB and VME readout boards will comply with the scheme. R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

12 Power Supply for FEB+DBB Firmware and Data Format Power Supply for FEB+DBB CAEN SY8800 has been selected 3 modules 110A/5V should cover all power needs The 3 modules will fit into one frame (shown below) It can be remotely controled via Ethernet, USB, CANBUS and RS232 R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

13 Schedule Production and Assembly Firmware and Data Format Power Supply for FEB+DBB The current plan for first EMR tests at RAL: May 30, 2011 Packing and shipment from UNIGE June 6, 2011 Arrival to RAL June 13, 2011 Installation in the hall June 20, 2011 Tests with Cosmics at RAL June 27, 2011 Tests with beam at RAL R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14

14 Cosmic Test Setup Production and Assembly Firmware and Data Format Power Supply for FEB+DBB Results from Cosmic Test Setup are coming soon... R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, March 24, / 14
