| | 7 | 1. Notes and actions from [wiki:Research/Instrumentation/Meetings/2019/08-29 last meeting]: |
| | 8 | * **KL**: Liaise to develop concept for polishing. |
| | 9 | * **Stands**: hold until polishing methodology is resolved. |
| | 10 | * **AK**: Prepare paperwork necessary to gain permission to work with source in 527. |
| | 11 | * **Done.** |
| | 12 | * **KL**: Check whether there was enough money to buy another 150mm stage. |
| | 13 | * **Done.** There was. Issue to be revisited today in the light of the requirement to purchase more fibre. |
| | 14 | * **KL**: Let D.Loader know that the other equipment may have to be sent without the SmartPhantom stuff. |
| | 15 | * **Done.** |
| | 16 | |
| | 17 | 2. Baseline schedule and progress against schedule: KL/HTL \\ |
| | 18 | The schedule was discussed and updated (see [raw-attachment:2019-09-18-SmartPhantom-Schdl.pdf updated schedule]). |
| | 19 | We discussed the schedule and agreed that we need to make a revision to reflect the present status of the development (**action KL**). |
| | 20 | |
| | 21 | Points noted: |
| | 22 | * LabView readout is ready for the test of the SciWire. Important now to define how teh detector will be read out at MedAustron. This could be a video (60 frms/sec). Agreed to add **action KL, AK, HTL** to consult to specify the data recording at MedAustron while the tests on SciWire are being carried out. |
| | 23 | |
| | 24 | 3. Experience with trial windings and discussion: LC, LTL \\ |
| | 25 | * [raw-attachment:2019-09-18-SmartPhantom-PrototypeLog.pdf Detailed log of prototyping to date.] |
| | 26 | * HTL presented the key points of the comprehensive note. The excellent discussion was hard to minute. However, we **agreed** that the next trial winding will be with the modified jig, circular aperture in the carbon-fibre frame, and perhaps test use of the various ideas put forward, including: |
| | 27 | * Clamping the fibure during winding; |
| | 28 | * Exploitation of adhesive tape to restrain fibre wile winding; and |
| | 29 | * Using adhesive spray to generate an adhesive surface to restrain the fibres during winding. |
| | 30 | * We **agreed** to "publish" HTL's note as a CCAP note. **AK** will invent a note numbering scheme which **HTL** will add to the header of the note so that he can post it as a CCAP note. |
| | 31 | |
| | 32 | 4. Mechanical design/manufacture update: LC \\ |
| | 33 | * [raw-attachment:190918-SmartPhantom.pdf Design update.] |
| | 34 | * LC presented the proposed modifications to winding jig and carbon-fibre frame. In the discussion, JB proposed that the fibre be annealed post winding to relieve the tension. The operatng range of the fibre from the data sheet is -20C -- +50C. So, annealing will need to be done at a temperatrure >50C. |
| | 35 | * We **agreed** to investigate whether this has been done by any other groups. |
| | 36 | * **Agreed** to make next test with a circular apperture. |
| | 37 | * **KL** will email D.Nardini and I.Clark to explain the teh next steps in the programme and to request machining of carbon fibre (two frames, two connector strips). |
| | 38 | |
| | 39 | 5. Control system and SciWire readout update: AK \\ |
| | 40 | * Progress to date noted under schedule discussion. |
| | 41 | * Connection of cameras to LapTop requires USB hub. Need to purchase additional (**action AK**) cameras and hubs. LapTop has three USB ports, so need 3 USB hubs. We **agreed** to buy hard-drive to store data but to defer the camera purchase. |
| | 42 | |
| | 43 | 6. Optical readout: JB \\ |
| | 44 | * Optical system specified. Outstanding issue is the detailed design of the piece that connects the fibre to the focusing system. We **agreed** to call this the //boot//. We **agreed** to take the optical components to LC so that he can finalise the design of the boot (**actions: transport of componenents KL/HTL, finalised design LC**). |
| | 45 | * Need to specify boot -- LC needs to know what it connects to. Take focusing device to LC. |
| | 46 | |
| | 47 | 7. Simulation/analysis update: HTL \\ |
| | 48 | * HTL had re-evaluated the impact of using a singlet layer on the performance of the SmartPhantom. The results, consistent with the last pass of single-layer evaluation, indicated that the change had a modest impact on performance. |
| | 49 | |
| | 50 | 8. Spend status, discussion of outstanding requirement: KL/All \\ |
| | 51 | [raw-attachment:2019-09-18-SmartPhantom-Csts.pdf Spend to date.] |
| | 52 | * We discussed the outstanding purchases that were required/being considered: |
| | 53 | * Scintilalting and clear fibre: estimate fibre cost for 5 stations: 150x150mm^2! square, 2 doublets, five stations: £18k. |
| | 54 | * **Actions: KL send fibre invoices to HTL; HTL provide spreadsheet with revised, precise estimate of fibre cost.** |
| | 55 | * Carbon fibre for frames (may need to order more) |
| | 56 | * Material/components for mounting of stations; |
| | 57 | * Cameras and associated optics |
| | 58 | * USB hubs and hard disk |
| | 59 | * Fishing line for tests. |
| | 60 | * We noted that the following items were not included in the costing: |
| | 61 | * Camera £469.20 |
| | 62 | * Optics £356.10 |
| | 63 | * Locking rings (£30.00) were included in stepper motor orer. |
| | 64 | * **KL** will prepare a revised spreadsheet for next meeting. |
| | 65 | |
| | 66 | 9. Next steps: All \\ |
| | 67 | * We **agreed**: |
| | 68 | * New winding test with circular frame; implies need for new frames and connector pieces; |
| | 69 | * SciWire tests; this will be also a prototyping of the optical r/p for SmartPhantom. |
| | 70 | |
| | 71 | 10. DONM \\ |
| | 72 | * Meet Tuesday 10:00 |
| | 73 | |
| | 74 | 11. AoB \\ |
| | 75 | * None. |
