HE FEE Boards production status 26 th May 2016 Mandakini Patil 1

Production of the boards Pulser Boards (ver3.1) Fabrication : 4 completely assembled boards were ready at Peninsula, Bangalore on 21 st May BV converter PCBs :90 boards ready and delivered to TIFR on 24 th May SiPM control boards : PCB work initiated –PCBs ready by 26 th May and assembly after that, to be delivered by May end Test stand work in progress : Test boards for SiPM control boards will get ready by next week Pin diode boards PCBs: 300 PCBs at TIFR (made by Yashna circuits Mumbai) in house assembly for 5 boards will be done by Pathare QIE Adapter boards : 50 completely done, will be available by Month end 26 th may 2016 Mandakini Patil2

Test stand setup at TIFR, Mumbai Test setup for the SiPM Boards testing and the Pulser boards testing is getting ready and we are testing 3 old SiPM boards Tested an old SiPM control board and are having some issues reading ADC1 correctly but will sort it soon, tested I2C communication to ADC2,DAC1 and DAC2 and even probed the voltages on the scope and they are all ok. The Load Resistance board to test SiPM control board will be ready tomorrow 3 Pulser boards (ver3.1) tested, using the Backplane and ngCCM control emulator and clock Emulator The first step of board checking for any inherent shirts was done at Bangalore itself after assembly at all the FEASTMP_CLP dcdc voltage outputs and all OK 26 th May 2016Mandakini Patil3

Testing of the 3 Pulser Boards After plugging in the boards,the firmware for ver3.1 HE_Pulser_ASIC.pdb was updated using FlashPro11.6 tool (in the FlashPro Programmer settings Vpump-3.3V must be ticked) After the successful firmware updating,using Raspberry pi,the I2c commands were given to make the LED ON Adjusted the amplitude with the I2C data transaction and LED responded accordingly Could not shine the LED light to the pindiode, as we don’t have the QIE Adapter and QIE boards anyway. Waiting for the full fledged test of the 4 th Pulser board ver3.1 to Fnal, to give a Go Ahead for production of pulser boards 26 th May 2016Mandakini Patil4

Aluminium Boxes status 5 Al Boxes dispatched last week and arrived at CERN ( Tina Vernon acknowledged) Another set of 5 Boxes parts all ready and some hole tapping work is on For these 5 boxes, the modifications will have to be made after returning from CERN in July and later incorporated here as well for the remaining boxes too Hopefully the updated design will be available soon too for the production boxes The next batch of 5 ore more boxes will be therefore sent after July..Is it OK..? 26 th May 2016Mandakini Patil5

3 Pulser Boards ver 3.1 tested fro all dcdc outputs and LED lighting and even regulated the LED light with the I2C commands and they are functional as expected SiPM control boards calibration test board underway QIE Adapter boards, Pin diode boards, SiPM control boards, BV converter boards production are all under way Inter connecting hirose cables (2 HiRose Coaxial connector H.FL75-2LP-084H-A-500 H.FL75-2LP-084H-A both ends female) procurement being done, but delivery may be after july only Will carry with us the fully tested 10 SiPM control boards, 10 BV converter boards and 3 Pulser boards with us to CERN by June 15 th th May Conclusions and Plans Mandakini Patil
