Figure 9
25 element array from PKI (C30985). The photograph in (a) shows one device. The central piece of silicon is 2 mm × 9 mm. In (b) the counts from two adjacent elements are measured when the array is scanned through a small X-ray beam. The elements are ∼250 to 300 µm (FWHM), with flat tops of ∼150 µm. The dead-spaces are indicated. Note that a scan in the orthogonal direction (not shown) gives the element width to be ∼440 µm (FWHM) with a flat top of about 220 µm. |
