我们已经开发了一种用于天体物理应用的具有定制、低噪声ASIC读出功能的大幅面CdZnTe像素探测器。特别是,这种探测器的目标是用于高能聚焦望远镜(HeFT),这是一种气球载实验,使用的是20-70keV的聚焦光学元件。该探测器是一个间距为498/SPLµ/m的24/SPL×44像素阵列。作为一种焦平面探测器,像素之间的一致性是非常理想的。本文给出了HeFT探测器上1056个像素的一些探测器特性的表征。这些特性包括电子噪声、泄漏电流、光谱分辨率和计数速率。
We have developed a large-format CdZnTe pixel detector with custom, low-noise ASIC readout, for astrophysical applications. In particular, this detector is targeted for use in the High-Energy Focusing Telescope (HEFT), a balloon-borne experiment with focusing optics for 20-70 keV. The detector is a 24/spl times/44 pixel array of 498-/spl mu/m pitch. As a focal plane detector, uniformity from pixel to pixel is very desirable. In this paper, we present the characterization of some detector properties for the 1056 pixels on the HEFT detector. These properties include electronic noise, leakage current, spectral resolution, and count rate.
