Projects
Dejardin / Fiber_irrad
Small PCB to handle PIN diodes to monitor the light attenuation of fibers during irradiations
Dejardin / HL-MEM_24C
24-channels HL_MEM to be able to read all PNs from a ECAL Super-Module. There are 2 tentative PCB : One to be located in the legacy MEM box outside SM and one to be located inside the SM at the place used by the Token-ring boards. Both have 24 LiTE-DTUs in test mode. Only other samples are read (80 MHZ sampling) and both MONACAL outputs are digitized and send to BE electronics through 2 FE boards.
Dejardin / FEM_v1
FEM_v1 consists of 2 small PCB : - One to handle the PN diodes (FEM_v1_PN) and - one which support the MONACAL chip (FEM_v1_MONACAL). This should fit on the allowed place on the Super-Module front face between 2 fibers raws
Dejardin / FEM_v0
Test board for MONACAL-v1 : - 1 MONACAL soldered for accurate tests and 1 MONACAL on test socket for fast production validation - 1 CATIA-v1.3 for Vinj generation - To be connected to ADC board used for CATIA irradiation tests (read by FEAD board) - Possibility for external charge injection - Possibility to insert long cable for MONACAL powering and signal return
Dejardin / HL_MEM_2C
2-channel HL_MEM to readout 1 FEM (2 PN diodes and one MONACAL) Use of LITE-DTU V1.2 in test mode to get only other samples To be plugged on a FEAD board
Dejardin / LiTEDTU_test
Almost same schematics as LiTE-DTU_calib, but with a test socket to be able to fast validate LiTE-DTU_v1.2 after production.
Dejardin / LiTEDTU_calib
VFE-like board with 1 CATIA and 1 LiTE-DTU to test CATIA-LiTEDTU interface and also noise from DCDC converters. Use CATIA-V1 and LiTE-DTU-V1.2
Dejardin / LMB
LMB stands for Laser Monitoring Board. It is foreseen to drive and monitor the lasers at HL-LHC. It will receive the 160 MHz clock and triggers info from lpGBT located on an embedded FE board (connected to a dedicated back end board). - There will be a 1280 MHz clock generator which will drive a fast 14 bits ADC to digitize a signal from a PIN diode to make an image of each laser pulse. The data of this ADC is splitted to 8 streams at 160 MHz using the compressed data format used for the barrel electronics. - There will be 7 LiTE-DTU to monitor the signals coming form the Spy-Box (11 PIN diodes (for 11 fibers) in parallel connected to a CATIA chip on each SpyBox submodule). Each Lite-DTU is streamed using the compressed data format used for the BArrel electronics. - All the streams are connected to the FE board to be sent to the Back-End electronics and thus be packed with the remaining part of the ECAL events. - The board generates triggers for lasers, DSO and others according to data received by the FE board. Each trigger can be tuned in delay. - There is also a connection by IPbus with a Gigabit ethernet port. For fast data monitoring and device programming - The board format is not yet fixed.
