硅钨热量计已被开发出来，可在 WiZard/CAPRICE 气球载实验中飞行，以测量宇宙辐射中反质子、正电子和轻核的通量。量热计由 8 个 x、y 硅采样平面 [有效面积 (48 × 48) cm2] 与 7 个钨吸收体（7 个辐射长度）交错组成；它提供了相互作用事件的拓扑结构以及沉积能量的独立测量。给出了前端电子设备和读出系统的细节，并描述了飞行前地面操作期间的整体性能。
A silicon-tungsten calorimeter has been developed to be flown in the WiZard/CAPRICE balloon borne experiment to measure the flux of antiprotons, positrons and light nuclei in the cosmic radiation. The calorimeter is composed of 8 x, y silicon sampling planes [active area (48 × 48) cm2] interleaved with 7 tungsten absorbers (7 radiation lengths); it provides the topology of the interacting events together with an independent measurement of the deposited energy. Details of the front-end electronics and of the read-out system are given and the overall performances during pre-flight ground operations are described as well.
