Notes
Participants: A Kurup, K Long, J Hughes, O Ettlinger, G Aymar, T Dascalu, C Whyte, HT Lau, J Pasternak, W Shields, J Parsons, T Greenshaw, G Schettino, J Matheson, J Pozimski, G Jones
Apologies: K Kirkby, K Gleason,
- Previous action items:
- AK, OE, GH, HTL and TD to continue discussing details of how to proceed with the laser-target simulations.
- Plan to run simulation in 3D and compare the resolution to what we can get for an equivalent 2D simulation.
- HTL just got an example Smilei input file from George Hicks and will go through it.
- JPar to email regarding fixing the best time for regular meetings on radiobiology.
- Will send an email to determine interest in setting up a separate meeting to discuss radiobiology activities. Need to see if we have a separate meeting or keep this in the weekly meetings.
- AK, OE, GH, HTL and TD to continue discussing details of how to proceed with the laser-target simulations.
- Publication
- Deadline was Monday. AK and KL received comments and is in the process of updating the paper.
- JPas still checking and will send comments soon.
- HTL checked dose rate calculations and found an error.
- Discussion on calculation
- See slides from HTL.
- JPas: Can look at SRIM. JPo has used this before.
- OE: We use SRIM for modelling radiochromic films. Problem is it only works on Windows.
- HT ran native Geant4 and saw same results as the BDSIM simulations.
- JPo: have SRIM on the tablet and will look at checking the energy deposition.
- Will continue discussion on this after the rest of the meeting.
- Discussion on calculation
- Capture - CW
- Getting things set up to do modelling. Making the right contacts to push this through.
- Looking at VSIM. Strathclyde has an old version. May want a newer one but it's very expensive. Cluster at Strathclyde has 300Gb RAM and may be available to run simulations on.
- Bob has physical dimensions to look at back of envelope calculations re diocotron.
- TD: Working on defining input file in prep for running.
- Stage 1 simulations
- TD: looking at tracking simulations using a transfer matrix and an idealised electric field for the lens. Discrepancy is much smaller now after discussing with WS (mainly due to the aperture needed to match the optics).
- Laser-target
- HTL: See above
- OE: GH is looking at estimating how long 3D takes, 8 years. Will look at optimising the calculation.
- AOB
- KL: micro-beams
- See slides on Micro-beam simulations from T. Schneider and Y. Prezado of the Curie Institut.
- Want to consider other energies.
- JPas: to calculate the beam properties properly will require some effort. Can think about incorporating the scanning magnet details in our simulations.
- Dose rate calculations
- HTL: May have found a bug, wrong value was used for the mass of the carbon beam.
- AK to install SRIM on the group's server.
- TG: Made contact with Carsten Welsch who is interested in scintillating fibre beam monitors.
- KL: micro-beams
Action items
- JPar to email regarding fixing the best time for regular meetings on radiobiology.
- AK to install SRIM on the group's server.
