HE FEE Boards and testing 30th July 2016 Mandakini Patil
Aim and Work Plan Aim to assemble 5 Calibration Units by integrating all parts as much possible and test the same while at cern upto 15th July Given 9 tested SiPM Control Boards (barcodes for these ?) to Danila 30 More SiPM control boards coming next week 30 BV converter Boards tested and here at CERN and within specs To setup a standalone Test stand for testing the SiPM Control Boards of next batch at CERN in B28 using Raspberry pi board 30th July 2016 Mandakini Patil
Status of the CU Assembly 3 Pulser boards for CU are fitted inside the Al box,2 more will be done Scintillator black box with pigtails to be fitted next week Thermal pads put for 4 CU plates,one more to be done Missing screws and spacers to fix the dc dc modules to the pulser board ordered and being sent by Keti LC/LC couplers for 50 CU and the 50 Patch chord fibers ordered (thanks to Tullio and Tina) SMA connectors and the 400micron Quartz fibers (to be sent by Vasken) One CU standalone test setup being sent to CERN by Keti from KSU QIE board angle connector removed but solder pads 30th July 2016 Mandakini Patil
Testing of SiPM control Boards Plans at CERN Needed a HDMI Monitor (thanks to Sasha’s Order for the same) Also got the 9V PS,the keyboard and mouse for the setup The HDMI Monitor that is hooked up to the Raspberry pi board Have taken a production backplane board with LV module Have a CCMEmulator, ngCCM Emulator with me (given by Joe ) Have the test board with loaded resistorsfor 48 channels Registered the raspberry pi board to get a IP no. for ethernet connection for the same The Pi Board gives the I2c commands needed to control the SiPM Control Boards Registers and also to control the LED pulse 30th July 2016 Mandakini Patil

Conclusion Gearing towards CU assembly and testing of 2nd batch of 30 SiPM control boards at CERN Testing of at least 1 – 2 HE CU with the one QIE card and integration with backend hopefully to be done soon. Next batch of 5 CU will be tested at TIFR in july last week and sent to CERN by 1st week of August Need a uHTR card to setup a test stand at TIFR for production boards testing ? 30th July 2016 Mandakini Patil
