PACS覆盖波长范围80-210微米的光谱和光度成像模式。长波相机是一个16 X 25像素的应力Ge:Ga探测器阵列。为了证明这种大型阵列的可行性，制作了25个线性阵列中的一个。它由16个1.5 mm3的元素组成，每个元素由陶瓷柱塞分开，并由一个单一的机构受力。在ISO光度计的基础上，研制了一种专用的CMOS电路作为前置放大器。特别是，它旨在增加CRE的增益，以尽量减少对低偏置操作的探测器的去偏效应。制作了两个完整的线性演示阵列，并在MPIA和MPE分别在1.7 K的低背景条件下进行了独立测试。所选择的概念的可行性在几个功能测试中得到了证明。获得了宝贵的经验，以指导下一代cre和阵列的发展。
PACS covers the wavelength range 80-210 micrometers in spectrometric and photometric imaging modes. The long wavelength camera is a 16 X 25 pixel array of stressed Ge:Ga detectors. In order to demonstrate the feasibility of such a large array, one of the 25 linear arrays was manufactured. It consists of 16 elements of 1.5 mm3 each separated by ceramic plungers and stressed by one single mechanism. As preamplifier a dedicated CMOS circuit was developed, based on similar circuits successfully operating in ISO's photometer. In particular, it was intended to increase the gain of the CRE in order to minimize the debiasing effects on the low bias operated detectors. Two complete linear demonstrator arrays were manufactured and independently tested under various low background conditions in a 1.7 K environment at MPIA and MPE. The feasibility of the concept chosen was demonstrated in several functional tests. Valuable experience was gained to guide the development of the next generation of CREs and arrays.
