     4
     5** Present:** KL, HTL, AK, LC, MP
     6
     71. Welcome/introduction: KL
     8 * We introduced ourselves: Liam, design engineer (RAL); HTL, AK, KL physicists (Imperial); Monika, responsible for dosimetry/instrumentation (TUW).
     9
     102. 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
     173. 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
     244. 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
     365. 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.
