摘要:

我们已经开发了一个微型TPC使用像素化的散装micromegas耦合到专用的采集电子作为读出允许重建几个千电子伏反冲的三维轨道。该原型已在IRSN-Cadarache的Amande设施进行了测试,提供单色中子。第一个结果有关歧视的几个千电子伏的电子和质子反冲。

英文摘要:

We have developed a micro-tpc using a pixelized bulk micromegas coupled to dedicated acquisition electronics as a read-out allowing to reconstruct the three dimensional track of a few keV recoils. The prototype has been tested with the Amande facility at the IRSN-Cadarache providing monochromatic neutrons. The first results concerning discrimination of a few keV electrons and proton recoils are presented.
