RadPix Meeting

Monday 16 Sept 2024, 10:00 → 18:00 Europe/London

337 (Oliver Lodge Building)

This meeting will be face-to-face at the Oliver Lodge Building (map here) for those who can attend in-person. There will be a zoom connection for those who are remote.

Zoom

1 RadPix brainstorming - Open questions

• In-pixel digital readout (ie hit buffers) inside the pixel (like in RD50-MPW4) or at the periphery (like MightyPix/LF-MightyPix) - pros and cons of each configuration
• LHCb requires 32-bit data words: RD50-MPW4 has 8-bit time-stamps, is this enough to achieve the required 3 ns time resolution? How many bits to address rows and columns in a 2 cm x 2 cm chip (RD50-MPW4 has 8-bit row address and 8-bit column address)
• How many FIFOs in the periphery given the data rate anticipated in Mighty Tracker and UP, to avoid loosing hits
• Pixel size will mostl likely be 100 um x 100 um, anticipate how this will benefit power consumption (distribute allowed power budget between pixel matrix and everything else)
• Plan to develop and evaluate enclosed layout transistors
• Voltage regulation

2 Lunch break

The Quarter

3 RadPix chip block diagram

• Sketch block diagram, think of main specs for all the main blocks, and estimate what 'should' be included in RadPix1/can be realistically designed until the chip submission

4 RadPix submission plan

• Anticipated timeline for submissions
• What blocks are included in each submission
• Who designs what block
• Person power and submission funding
• Design files sharing

5 Coffee break

• Can also include a quick lab tour to show HV-CMOS experimental setups (RD50-MPW4, UKRI-MPW1 and MightyPix)

6 RadPix submission plan (continuation)

7 Progress since last in-person meeting

• Summary of relevant measured results (RD50-MPW4, UKRI-MPW1 LFoundry prototypes)
• Plans for TID evaluation at RAL in late October or November
• We've never measured SEU tolerance

8 Anticipate DAQ

• 'Standard' options are Caribou (used with RD50-MPW and UKRI-MPW), GECCO (MightyPix) and MARS (MightyPix)
• Pros and cons of each option
• What DAQ should we use to maximise the number of institutes contibuting to the evaluation programme?
