LAr LAPP meeting 2025-03-11

 

Calibration Board

 

• CHALET
• Cannot generate trigger signal from devkit CASA/CHALET
• Devkit still fonctional, but FPGA pin always at 2V (broken?)
• Nécessite enlever une des connection sur cage SFP pour le démarrer correctement (?)
• TODO temporary replace with CABANE devkit
• TODO give broken devkit to JMN to verify if fixable
• TODO buy new devkit?
• LDO issue
• Scanner patch cable done
• Code started
• OPC-UA “tutorial” to be done (Florent, Olivier -> Oleksii, Marco)
• Add common pulse test to sequencer (currently missing)

 

• MUX
• Issues with prototype cabling (components break during oven cabling - no coating?)
• Problems with PCB design and fabrication
• PCB to be redesigned and resubmitted

 

LATS

 

• Boards at LAPP
• LATOURNETTE 2 in ATCA crate, running to heat up board
• IPMC temperature threshold at 35 C
• When ATCA crate doors opened, -5 C temp change observed!
• FireFlys need to be < 50 C
• TODO change threshold table [Sylvain]
• Air conditioning on?
• Add temperature probes to lab?
• Concurrent access to LATS
• TODO shared calendar (or other reservation tool) to “reserve” use of setups [Sylvain, Nicolas]
• Power Input Manager (PIM) always at 1?
• Fond de panier support 1 repaired [JMN]
• JMN’s tests on PowerGood: board randomly offing as previously observed by FB and SL
• JMN has an hint of a possible cause, under investigation (capacitance?)
• Regardless, tin future his board will only be used on table with direct powering (if so, recover IPMC board - SL)
• Still waiting for front panes [JMN]

 

• Firmware
• FEX block from LATOME FW to receive LTI and others (implemented during LASP Integration Week) [NC]
• Needs to use LATS board at LAPP for FW development [NC]

 

• RTM
• Pin configuration to use AMC received from Stefan Haas [FB]
• To be implemented in next code sprint [SL]

 

• IPMC
• Mac addresses to be declared at CERN [NC]
• TODO: FB to verify MAC address list - paper in box?
• Add IPMC MAC address to production database?
• Also FW version and (compilation) date?

 

 

LAr Online

 

• Ferio
• Issue with communication with CASA board (?), now working with CABANEv3
• Ongoing investigations:
• Difference with licensed vs open source OPC-UA server librarr?
• Errors with serial and parallel methods being investigated?
