Pneumatic Cylinders Controlled by Solenoid Valves and Pressurized Gas System Swivel Screws Optically Clear Cast Acrylic Tube, ¼” Thick, 1” Wide, OD 5” Square-Flange Mount With Set- Screw Lock (1/2" Shaft Diameter) We need to devise a locking mechanism that allows the support structure to rotate in 6 deg intervals. Ideas? Soft Rubber/ Foam

Mass of each ring: 0.08 lbs = grams

How does the carbon fiber support attach to the chassis? Is it removable? Chuck’s Drawing

30 ft 2 of foil needed to wrap 100 scintillators (enough for prototyping and final wrapping) Aluminum 1000 series.00035” (8.9 μm) x 28” wide x coil, 30 square feet, $ lot charge Aluminum 1000 series.0005” (12.7 μm) x 25” wide x coil, 30 square feet, $ lot charge Aluminum 1000 series.0007” (17.8 μm) x 25” wide x coil, 30 square feet, $ lot charge Possible to order smaller quantities Sales associate indicated that the foil has a matte finish (this is not suitable if one side is not reflective however the sales associate was not sure if one side was reflective) Sample foil (6” x 6”) has been ordered to inspect finish We measured the thickness of food grade Aluminum foil to be ~ 16 μm

This would require scintillators to wrapped in 4 sections 2 in the straight section, 1 in the bend, 1 in the nose Templates will need to be made Reflectivity is exactly that of food grade Aluminum foil No sample offered but single sheets are inexpensive 90 Sheets needed for 30 scintillators ~180 Sheets needed for prototyping and final wrapping $2700 for 180 Sheets

They offer.0003” (7.63 μm) as well Quote is being ed by end of week, samples will be ordered after receiving quote Prices should be comparable to Comet Metals as they are “fierce” competitors
