电阻网气体探测器的初步试验

First Tests of Gaseous Detectors Made of a Resistive Mesh

R. Oliveira, V. Peskov, F. Pietropaolo, P. Picchi

摘要:

我们在这里描述各种探测器设计:GEM型,MICROMEGAStype,PPAC型以及级联探测器,由电阻网格制成,电阻网格由电阻Kapton箔制成,(20微米厚,电阻率为每平方几MOhm)通过激光钻孔技术。与任何其他微图案检测器一样,这些检测器的最大可实现气体增益受到Raether极限的限制,然而,电阻网格使它们和前端电子器件完全受到火花保护。这种方法可以是开发具有电阻阳极读出板的MICROMEGAS和GEM的持续努力的替代或补充,并且在与微像素型集成前端电子器件组合的微图案检测器的情况下可以是特别有益的

英文摘要:

We describe here various detectors designs: GEM type, MICROMEGAStype, PPACtype as well as cascaded detectors made of a resistive mesh manufactured from a resistive Kapton foil, (20 microns thick, resistivity a few MOhm per square) by a laser drilling technique. As in any other micropattern detectors the maximum achievable gas gain of these detectors is restricted by the Raether limit, however, the resistive mesh makes them and the front end electronics fully spark protected. This approach could be an alternative or complimentary to the ongoing efforts in developing MICROMEGAS and GEMs with resistive anode readout plates and can be especially beneficial in the case of micropattern detectors combined with a micropixel-type integrated front end electronics
