| 25 | | - Introducing Simon |
| 26 | | - Update on next prototype |
| 27 | | - Fast electrons |
| | 32 | - Simon is a Master's student who will join us till the end of February and will focus on the scifi array |
| | 33 | - There are spare days in November for use of the Cyclotron |
| | 34 | - We should book those and we can test the scifi there |
| | 35 | - Can also test the transwell setup with scifi around the edge |
| | 36 | - If nothing else can test a bundle of clear fibre to see if it scintillates |
| | 37 | - Tony can match our variation in beam, as long as there is enough time to simulate it beforehand and get the right scatterer |
| | 38 | - If it does scintillate, could remove that light by using a filter since the scintillation light from the transport fibre and the scintillation light from the array will have different wavelengths. |
| | 39 | - Fast electrons (Richard's and Giuseppe's notes) |
| | 40 | - Electrometer |
| | 41 | - With enough time, could be manually controlled between pulses |
| | 42 | - Measure off-axis |
| | 43 | - XDS Oxford IC SPEC |
| | 44 | - Thin-windowed ion chambers |
| | 45 | - £20K (maybe get on loan) |
| | 46 | - 20um thick |
| | 47 | - Giuseppe's Notes: The windowless chamber that I was thinking of, is an extrapolation chamber that determines absorbed dose by measuring the ionisation produced in a very small air cavities while varying the electrode separation and extrapolating the collected charge to zero cavity thickness (i.e. at the entrance of the chamber which is where the cells will be). However, for very low-energy proton beams, the proton range may be comparable to the cavity dimensions and the energy deposition can vary strongly over very short distances. Consequently, the extrapolation procedure would not work since the method relies on the assumption that the charged-particle fluence and dose distribution remain approximately uniform across the cavity. |
| | 48 | - Need a better understanding of the electron to proton distribution |
