细晶硅钨量热计非常适合用作针对粒子流重建而优化的线性对撞机探测器中的电磁量热计。我们正在设计一种基于读出芯片的量热计，该读出芯片凸点接合到作为量热计中的活性介质的硅晶片。通过使用集成电子器件，我们计划证明可以以合理的价格实现细粒度。我们的设计最大限度地减少了钨层之间的间隙，从而实现了较小的莫里哀半径，这是粒子流探测器的重要品质因数。讨论了测试光束原型中使用的硅探测器的测试以及基于类似硅探测器的定时测量。
A fine grained silicon-tungsten calorimeter is ideal for use as the electromagnetic calorimeter in a linear collider detector optimized for particle-flow reconstruction. We are designing a calorimeter that is based on readout chips which are bump bonded to the silicon wafers that serve as the active medium in the calorimeter. By using integrated electronics we plan to demonstrate that fine granularity can be achieved at a reasonable price. Our design minimizes the gap between tungsten layers leading to a small Moliere radius, an important figure of merit for particle-flow detectors. Tests of the silicon detectors to be used in a test beam prototype as well as timing measurements based on similar silicon detectors are discussed.
