= SmartPhantom meeting: Wednesday 24^th^ July 2019, 11:00 BST = == Notes: == **Present:** KL, LC, JB, AK, HTL 1. Notes and actions from [wiki:Research/Instrumentation/Meetings/2019/06-26 last meeting]: * **HTL**: Inject 90Sr electrons to estimate test-rig light yeild. \\ * **Done.** Simulation estimating number of photo-electrons created (see [raw-attachment:Sr90_ly.png slides]). Now await measurement to allow comparison. * **Agree:** Make measurement of activity of source using silicon detector. This was done; the rate measured was 90kHz. * **KL**: Liaise to develop concept for polishing. \\ * **Ongoing.** Possibly use diamond cutter after having glued two planes together to form station. * **KL**: Work within Imperial to find assembly space. * **Done.** * **KL**: Seek meeting with S.Gruber to get her input into the design. * **Ongoing.** * **LC**: Obtain chemical composition of resin and black dye. \\ * **Done.** Carbon-black pigment. Its composition is "like" resin. **KL** send MuScat paper for reference. * **LC**: Develop concept for optical connector at camera end of lightguide and for potting of light guide at detector end. \\ * **Done.** Example part has been printed. We discussed the dimensions and agreed to make it one piece. * **KL**: Liaise with FW to work out how to place aluminium-part order. * **Done.** Order may be placed on the code used for other components. * **JB**: Purchase parts for optical readout system. * **Done.** All parts for prototype are ordered. Optical system [raw-attachment:projection_assembly.pdf concept] developed and initial sketch uploaded. * **AK**: Provide JB with project code for purchase of optical readout components. \\ * **Done.** 2. Mechanical design update: LC \\ * See [raw-attachment:240719-SmartPhantomDesign.ppt slides]. Excellent discussion, next steps noted in LC's slides. Imperial my make sheet-metal stand. * We **agreed** to assemble jig at RAL because of need to measure accuracy of assembly. Implies some technical effort from RAL. **LC** will see if this is available. 3. Optical readout update: JB \\ * We discussed the [raw-attachment:projection_assembly.pdf concept] that had been circulated. JB demonstrated the concept with parts (holder, lens assembly, locking ring). * Concept seemed good. Light tighting felt to be straightforward. * **LC/JB:** Agreed to finalise specification of interface between clear-fibre connector and optical assembly. 4. Control system and SciWire readout update: AK \\ * Will use LabView. AK has requested LabView license for himself and HTL. Work will be divided between AK and HT. * Need to purchase laptops to run/develop system: one for development one for development and operation of system. * Stepper motor with travel of 150mm will be purchased from ThorLabs. Order will include two locking rings for optical system. * **JB** will send part number to AK. 5. Simulation update: HTL \\ * Points noted above. 6. Schedule: HTL and discussion (all) [raw-attachment:smartphantom.png Gantt Chart] \\ * Discussion of [raw-attachment:smartphantom.png schedule] led to conclusion that there is a need to advance the construction etc. as far as possible. * Agreed to wind first prototype planes with scifi (not fishing line). Hope that these will be acceptable detectors for use. * We **agreed** to meet next Tuesday (time to be defined) to make a first baseline version of the schedule **KL** to suggest time. 7. Next steps \\ * Preparation of components indicates that assembly of winding jig could start after 12Aug19. Need to watch this space. 8. DONM \\ * 07Aug19 9. AoB \\ * None. === Summary of actions === * **KL**: Liaise to develop concept for polishing. * **KL** send MuScat paper for reference. * **KL**: Seek meeting with S.Gruber and/or M.Puchalska to get her input into the design. * **LC**: Check re technical effort at RAL for assembly/dowling etc. * **LC/JB:** Finalise specification of interface between clear-fibre connector and optical assembly. * **JB** Provide ThorLabs part numbers of remaining optical components to AK. * **KL**: Suggest time for schedule discussion on 30Aug19. ---- == Meeting details == Blackett 521 (The Tutorial Room) and teleconference Phone details: {{{ UK: 08082 380274 Austria: 0800 006612 PIN: 5904750902 }}} Full list of telephone contacts may be found [https://ccap.hep.ph.ic.ac.uk/trac/raw-attachment/wiki/Communication/Z0-Phone-details.pdf here]. == Agenda: == 1.
