摘要:

提出了一种新的电离探测器读出方法。该解决方案允许最小化部件的数量和靠近检测器的空间占用。这样,在那些预期信号率非常低的实验中,如GERDA和MAJORANA,对放射性背景的影响最小。该电路包括一个JFET晶体管和一个远程第二级。直流反馈路径使用二极管闭合。两条信号电缆仅用于偏置和读出。

英文摘要:

We present a novel approach to the readout of ionization detectors. The solution allows to minimize the number of components and the space occupation close to the detector. This way a minimal impact is added on the radioactive background in those experiments where very low signal rates are expected, such as GERDA and MAJORANA. The circuit consists in a JFET transistor and a remote second stage. The DC feedback path is closed using a diode. Two signal cables are only necessary for biasing and readout.
