摘要:

厚类GEM(THGEM)电极是坚固的高增益气体电子倍增器,通过薄印刷电路板或其他材料的标准钻孔和蚀刻经济地制造。它们的操作和结构与标准GEM相似,但尺寸扩大了5至20倍。由于较大的孔尺寸,它们在单电极级联和双电极级联中分别提供高达10^5和10^7的电荷倍增。信号上升时间只有几ns,计数率在10^4增益下接近10 MHz/mm^2。亚毫米定位精度证明了一个简单的,基于延迟线的二维读出方案。这些倍增器可以以各种形状和尺寸生产,并且可以在许多气体中操作。它们可以在许多需要非常大的面积、鲁棒、平坦、薄的探测器的应用中取代标准GEM,具有良好的定时和计数率特性以及适度的定位。简要介绍了这些乘子的性质,并讨论了可能的应用。

英文摘要:

Thick GEM-like (THGEM) electrodes are robust, high gain gaseous electron multipliers, economically-manufactured by standard drilling and etching of thin printed circuit board or other materials. Their operation and structure are similar to that of standard GEMs but with 5 to 20-fold expanded dimensions. Due to the larger hole dimensions they provide up to 10^5 and 10^7 charge multiplication, in a single- and in two-electrode cascade, respectively. The signal rise time is of a few ns and the counting-rate capability approaches 10 MHz/mm^2 at 10^4 gains. Sub-mm localization precision was demonstrated with a simple, delay-line based 2D readout scheme. These multipliers may be produced in a variety of shapes and sizes and can operate in many gases. They may replace the standard GEMs in many applications requiring very large area, robust, flat, thin detectors, with good timing and counting-rate properties and modest localization. The properties of these multipliers are presented in short and possible applications are discussed.
