Read out Hamamatsu S17285 with NI-DAQ

• Install LabView on PBT Intel MacBook Pro.
• Set up NI-DAQ USB6366 to output test patterns on selected pins:
  • Write custom VI to output chosen frequency test patterns (different on each pin).
  • Test output with scope.
• Replicate Saad's DDC232 slides with detailed signals for communicating with S17285.
• Communicate with S17285 with NI-DAQ...

Replicate Raspberry Pi/USB104 readout with Kria and IC KriaDAQ board

• Implement USB-C cable tester using IC KriaDAQ:
  • Output test signals from single USB-C port (FW only?): Andy Rose/Matt Warren/Erdem Motuk.
  • Test signals for each channel with different frequency.
  • Use LVDS pairs for 5 differential pairs; check existing firmware for single-ended signals.
  • Measure output with scope.
  • Set up IPBus communication between PS and PL: talk to David Sankey.
  • Read output with second USB-C connection.
  • Collect output and "display" with PS.
• Migrate USB104 firmware and FTDI C++ code to Kria:
  • Connect DDC board via USB-C: check for power!
  • Send configuration and read back test pattern.
  • Adapt buffer for Kria hardware: Andy Rose/Matt Warren.
  • Read back live photodiode output from DDC board.
  • Read back live photodiode output from 4 DDC boards.
• Extend readout to multiple KriaDAQ USB-C connectors.
  • Single board each on 2 connectors.
  • 4 boards each on 2 connectors.
  • Extend to 5 USB-C connectors.
• Control readout with web GUI.

Power supply board

Ready for experimental visit to Trento, 28th September 2025

• Power distribution board required for QuARC.
• Provide power for Raspberry Pi and DDC boards from single DC input:
  • 5V/5A for Raspberry Pi via USB-C
  • >7.5V (5A?) for DDC board daisy chain via 2.5mm barrel
• Single USB-C PD input: 20V/5A
  • Needs USB-C PD voltage negotiation chip
• Fallback option with 20V DC 2.5mm barrel jack input
• LEDs to indicate each voltage is provided correctly:
  • 20V input
  • 5V to Raspberry Pi
  • >7.5V to DDC boards
• Should be able to switch off LEDs
• Necessary to switch between input power supplies?
• Ensure both power outputs stable: no drop-outs!
  • Potential for USB-C PD to drop out when voltage renegotiated?

DDC Photodiode Board Rev.G

Upon completion of power distribution board

• Return Rev.F boards and ZMOD boards to be fixed: ✓
• Remove RESET connection from CC2 pin on all DDC board USB-C connections
• Resize DDC board to accept Hamamatsu S12362 16-element photodiode array in place of Hamamatsu S12915-16R single photodiodes
• Reduces pitch from 3mm to 2.5mm
• 2 photodiode arrays per DDC board (2 x 16 element arrays = 32 channels)

Scintillating Fibre Profile Monitor Front-end Boards

Upon completion of Rev.F board

• Integration of scintillating fibre profile monitor based on design from Blake Leverington, University of Heidelberg
• Hamamatsu S17285 photodiode arrays to couple to scintillating fibres
• Interface board needed between USB-C connection from FPGA and photodiode arrays
• Acquire data; distribute timing signals

QuADProBe FPGA Upgrade

• QuADProBe QAD to be upgraded from USB104+Raspberry Pi to Kria:
  • AMD Kria K26 SoM
  • Kria K26 SoM Data Sheet
  • Kria KV260 AI Vision Starter Kit
• Kria available off-the-shelf but carrier board needed
• Imperial to design carrier board with multiple I/O for QuADProBe:
  • Imperial One-drive folder for Kria DAQ Documents
  • Evolution of QuARC Electronics (PPTX)
