论文摘要
已经设计和构造了一种新型的量热计的原型，该原型是基于使用具有数字读数的像素传感器的硅 - 刺采样设计。它利用为爱丽丝升级而开发的Alpide Maps传感器。由于像素大小约为$ \ 30 \ times 30 \，μ\ mathrm {m}^2 $，因此可以进行二进制读数。该原型已通过宇宙muons成功测试，并在DESY和CERN SPS上进行了测试梁。我们报告在DESY获得的性能结果，显示出良好的能量分辨率和线性性，并与详细的MC模拟相比。还显示了在SPS上测量的高能性能的初步结果。讨论了两个夏季的分离功能。
A prototype of a new type of calorimeter has been designed and constructed, based on a silicon-tungsten sampling design using pixel sensors with digital readout. It makes use of the Alpide MAPS sensor developed for the ALICE ITS upgrade. A binary readout is possible due to the pixel size of $\approx 30 \times 30 \, μ\mathrm{m}^2$. This prototype has been successfully tested with cosmic muons and with test beams at DESY and the CERN SPS. We report on performance results obtained at DESY, showing good energy resolution and linearity, and compare to detailed MC simulations. Also shown are preliminary results of the high-energy performance as measured at the SPS. The two-shower separation capabilities are discussed.
