Figure 1
Single-channel diamond mounts. Diamonds are metallized with a layer of Pt on each side. Copper electrodes (orange, labeled 1) contact the diamond. Ceramic insulating material (Macor) is shown in black. (a) `Timing' mount. This holder allows timing measurement, but holds only 4 mm × 4 mm diamonds. Copper photoemission guards (orange, labeled 2) are biased to retard photoemitted electrons from the metal on the diamond surface to ensure that only the signal from the X-ray absorption in the diamond material is measured. Ruby balls (red) insulate the guards from the electrodes. The blue regions represent the stainless steel grounded outer holder. (b) `Claw' mount. This holder can accommodate a range of diamond sizes and can be used for response mapping. |
