| | 7 | 1. Welcome/introduction: KL |
| | 8 | * We introduced ourselves: Liam, design engineer (RAL); HTL, AK, KL physicists (Imperial); Monika, responsible for dosimetry/instrumentation (TUW). |
| | 9 | |
| | 10 | 2. Status of SmartPhantom preparation: HTL |
| | 11 | * [raw-attachment:meeting1.pdf Slides]. Points noted: |
| | 12 | * In preparation for the exposure we may need to plan a CT of the SmartPhantom for the TPS calculation. |
| | 13 | * In the measurement plan we need to include: |
| | 14 | * An exposure with the SmartPhantom and an ionisation chamber to cross calibrate the energy reconstruction; and |
| | 15 | * An exposure with the SmartPhantom and the "Linx camera" to cross calibrate he position reconstruction. |
| | 16 | |
| | 17 | 3. Water phantom and preparation for beam at MedAustron: MP |
| | 18 | * [raw-attachment:MP-IMG-1.jpg Sample holder in water phantom]; |
| | 19 | * [raw-attachment:MP-IMG-2.jpg water phantom, front view]; |
| | 20 | * [raw-attachment:MP-IMG-3.jpg sample holder]. |
| | 21 | |
| | 22 | * The phantom that is being planned for the measurements is the same as that used as the basis for the SmartPhantom design. |
| | 23 | |
| | 24 | 4. Discussion and next steps |
| | 25 | * Ethernet is available in the research room; |
| | 26 | * **MP**: Will check the beam energy spread, perhaps as a function of energy. |
| | 27 | * There is a trigger signal in the research room. It seems likely that this is the synchrotron cycle-start signal. **MP**: agreed to check the definition of the trigger signal. |
| | 28 | * The electronics should go to the side of the water phantom, not behind. **MP**: will make a sketch of the space available for the water phantom, the SmartPhantom, and its electronics. The couch will be included in the sketch. |
| | 29 | * We need to develop an installation, commissioning, calibration, and exposure plan. **Agreed** to work on this together. |
| | 30 | * It is permitted to use stainless steel studding in the station supports. |
| | 31 | * We **agreed** to consider the construction of a model to allow an early fit-check. |
| | 32 | * What is the minimum distance from the flask that we can put the detector? We have a flask at Imperial and can begin to study this. |
| | 33 | * We agreed that **MP**: would make a sketch ('technical drawing') of the water phantom. **HT**: will circulate and post the water phantom specs. |
| | 34 | * We discussed the requirement to position the SmartPhantom accurately and to maintain its position. **LC**: will consider the positioning mechanism. |
| | 35 | |
| | 36 | 5. DONM |
| | 37 | * Standing invitation to MP to join SmartPhantom meetings. Contact with MP can be maintained by email and phone. Specific meetings can be arranged as required. |
