**ZOOM:** https://imperial-ac-uk.zoom.us/j/98220889714?pwd=SM90vOF7BKSXoU3mD9q7OwBQo4IVB3.1 

Attended: KL, CW, CD, (JB)

== Meeting Notes == 

1. General Discussion
 - Robbie mentioned that beamtime might be more likely in February. 
 - Colin believes we might be able to get some time in Autumn if we can time it correctly with other beamtime.
 - There is work where the SCAPA team are using AI and looking at the variability of the laser.
 - Colin to discuss with Robbie how to build the setup with another experiment

2. Instrumentation
 - General 
  - Colin suggested filling the carousel and running 1 shot then repeating with 2 shots etc
  - Each cell dish would have Lanex around it or something for real-time measurement
  - Then we could skip the calibration stage by comparing the variation in the Lanex signal with the known variation in dose
  - Problems involve the number of cells needing to be collected and the time that would take
  - Needs discussion with bio team
 - SciFi
  - Need to actually test whether the transporting fibre will scintillate
  - Operate on the assumption it does not
  - If it does Peter has ordered hollow-fibre
  - Might be able to use a standrad fibre-optic connector
 - ICT
  - Colin has ICTs
  - 3-5ns rise time, so should see the short pulses but on the edge of visible and may be blurred out
  - 0.1V in signal per Amp in beam current
  - Beam would also need to be roughly symmetric, so has to be after the scatterer

3. Overview of Trello
 - Reminder plan is laid out in the google doc and can be changed
 - Trello: https://trello.com/invite/b/67587c515b0c69656ee78b48/ATTIe86f94b24e3e5884e4cb87e5ed3b89ab64321B83/poplar
