摘要:

介绍了一种装备齐全的中型30 $\times$ 30 cm $^2$电阻板阱(RPWELL)探测器的束内评价。它包括一个单元件气体雪崩倍增器,带有Semitron ESD 225电阻板、1 cm $^2$读出焊盘和APV 25/SRS电子器件。类似于以前的结果与小型探测器原型,稳定运行在高检测效率(>98%)和低平均垫多重性(~1.2)记录与150 GeV的μ子和高速率的π介子束,在Ne/(5%CH $_4$),Ar/(5%CH $_4$)和Ar/(7%CO $_2$)。这是实现适用于需要大面积覆盖的应用的鲁棒探测器的重要一步;其中包括数字强子量热法。

英文摘要:

In-beam evaluation of a fully-equipped medium-size 30$\times$30 cm$^2$ Resistive Plate WELL (RPWELL) detector is presented. It consists here of a single element gas-avalanche multiplier with Semitron ESD225 resistive plate, 1 cm$^2$ readout pads and APV25/SRS electronics. Similarly to previous results with small detector prototypes, stable operation at high detection efficiency (>98%) and low average pad multiplicity (~1.2) were recorded with 150 GeV muon and high-rate pion beams, in Ne/(5%CH$_4$), Ar/(5%CH$_4$) and Ar/(7%CO$_2$). This is an important step towards the realization of robust detectors suitable for applications requiring large-area coverage; among them Digital Hadron Calorimetry.
