Experiment Equipment
| Item | Notes |
|---|---|
| Portable Enclosure | Modified Small Peli Case Wheeled. Features mount for scintillator stacks, front and back openings for beam, patch panel with ports. Mylar windows with 3D printed alignment plates: approximately light-tight. |
| Rev. D Scintillator stack 1 | 32 X x 105 mm, Y x 105 mm and Z x (approx) 3 mm sheets. Original injection moulded batch with polished edges and sanded faces. Containing sheets (ascending photodiode order, board upside down): 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168. Full stack thickness measurements (in mm): 95.75, 96.02, 96.09 = 95.95 |
| Rev. D Scintillator stack 2 | 32 X x 105 mm, Y x 105 mm and Z x (approx) 3 mm sheets. Machined block with polished edges and sanded faces. Containing sheets (ascending photodiode order, board upside down): 289, 268, 291, 277, 300, 264, 282, 276, 271, 285, 262, 280, 295, 281, 297, 290, 270, 284, 294, 299, 269, 302, 301, 296, 287, 263, 288, 293, 285, 265, 275, 292. Full stack thickness measurements (in mm): 96.89, 96.85, 96.70 = 96.81 |
