Preparation for UCLH beam tests 29-30th April
- New scintillator stack holders:
- Stack holders 3D printed: remake by hand if time allows.
- Mounting plate to screw to Thorlabs optical breadboards in Peli cases:
- Rough version already 3D printed.
- Needs modifying to fix stack holder in place with M14(?) nuts.
- Must be able to mount upside down.
Full detector scintillator holder
- We need to go from the prototype version bolted to the optical plate to something completely standalone.
- We can probably put it in another Peli case — I have loads — initially with an optical breadboard but eventually without.
- It needs a support structure that is not rigidly bolted to the case but will align to any windows we cut: that means clinical staff can whack the detector and it won’t break or go out of alignment. So something internally sprung.
Completed
2023
- January-May
- Enclosure design for small-scale Clatterbridge detector prototype (with Simon).
- Includes feedthroughs, mounts for NUC PC, Raspberry Pi and USB104 FPGA.
- Nozzle mounted
2022
- November-December
- Design and 3D print external frame with alignment marks and alignment plates for small Peli case.
- Duplicate alignment bar from Zarges case with circular studs to allow alignment with treatment couch.
- October
- Modified medium-sized Peli case ready for beam tests:
- Install Thorlabs optical breadboard in base of case.
- Cut out window at each end of case for mylar window installation.
- Cut out 2 windows for 2-gang patch panels, 1 per side.
- Cut out 2 windows for 1-gang patch panels, 1 per end.
- 3D print internal frames for mylar windows with bolt holes in each corner. Drill bolt holes in Peli case.
- 3D print external frame with alignment marks matching centre line of optical breadboard (vertical) and 71mm above optical breadboard (horizontal). Match bolt holes to mylar window frames.
- 3D print alignment plates that are strong enough to double as external cover plates when shipping enclosure.
- September
- Machine a patch panel complete with 10 smaller panels that can be swapped between on the main patch panel to allow for various electrical feedthroughs
- August
- Created CAD cross hair for Peli Case to be printed. Also created small printed windows to clamp Mylar smooth over the beam entry point.
- July
- Created CAD models for internal components including:
- Scintillator holder.
- 2x Side Vice faces.
- 1x Front Vice face.
- Cover for beam entry point.
- These were printed soon after.
- Beam entry point was cut out of the case, piece was sent for testing with Adam Gibson.
- Machined two special 1/4-20 UNC screws for camera mount.
- Tapped all holes on Scintillator holder to take m5 nylon screws to allow vice faces to travel.
- June
- Initiated design of large Peli Case. Received Lab scissor jack used to mount camera.
- May
- CAD Prototype a sliding system to mount multiple scintillator holders into a case
- February
- Create CAD model for small Peli Case so ideas on how to install the holder into the case can be prototyped
2021
- November
- Design initial prototype of a new holder that will clamp scintillator sheets together. Will supersede previous adhesive idea
- June
- Prepare scintillator sheets to be adhered together using standard primer
