Minutes for UCL Proton Beam Therapy Group Meetings, 4th March
Present
'Joe Bateman, Sonia Escribano, Febian, Harry Barnett, Simon Jolly, Raffaella Radogna (via Teams)
Harry Barnett
- Daetron to be delivered on wb 7th April
- Sorting air handling unit in the workshop on 2nd April
- Vacuum pump already delivered
Raffaella Radogna
- Debugging setup of fibres in Bari
- Producing new connectors and cables
- Outcome from meeting Blake last Friday and how to move forward
Joe Bateman
- Finalising slides and talk for PPRIG
Simon Jolly
- Circuit boards being investigated by Oxford and looking at remaking zmod boards
- Ddc boards have arrived in Oxford and have been looked at by Pete and should hopefully be okay
- Matt has bypassed shorts on one of the zmod boards by brute force to work so can test ddc boards and zmod boards
Sonia Escribano
- Upgrading calibration process
- Shoot through files (2 per calibration) how many off-centre measurements - depends on available beam time but at least 4 ideally (up, down, left, right)
- Acquire data with both boards simultaneously for calibration of each stack
- Doesn’t matter if we do or don’t have live display of uncalibrated data for this part
- Calculating WET of each stack - included beam time request for each module front and back
- Had a look at reversed board acquisition and need to be weary of photodiode position of where BP occurs for reconstruction
- However when using multiple stacked will only have to use one beam direction so this issue with flipping twice will not be necessary
- Will eventually need to give one single calibration file including weightings if necessary for different beam positions
