论文摘要
2021年11月在Desy Beam测试设施中测试了Calice Silicon-Tungsten Ecal的扩展版本。它具有15个活跃的层，其中一些具有薄PCB设计，以及一个新的紧凑型DAQ系统，可在公共组中处理所有层。使用改进的程序，已经评估了15360个通道中的每个通道中的每个通道的噪声，自触发性能和对冲压电子的响应 - 尽管没有钨吸收剂。低能电子（1至6 GEV）的淋浴已在两种吸收仪中记录，并正在分析。将提出一些细胞水平的初步结果。
An extended version of the CALICE silicon-tungsten ECAL was tested in November 2021 at the DESY beam test facility. With 15 active layers, it featured some with a thin PCB design, and a new compact DAQ system handling all layers in a common set. The noise, self-trigger performances and response to punch-though electrons, without tungsten absorbers, have been evaluated for each of the 15360 channels, using an improved procedure. Showers of low-energy electrons (1 to 6 GeV) have been recorded in two configurations of absorber, and are being analysed. Some preliminary results at the cell level will be presented.
