标题： A new approach to the front-end readout of cryogenic ionization detectors

摘要： 我们提出了一种电离探测器读出的新方法。 该解决方案能够将组件数量和探测器附近的占用空间最小化。 这样，在那些预期信号率非常低的实验中，如GERDA和MAJORANA，对放射性本底的影响最小。 该电路包括一个JFET晶体管和一个远程第二级。 使用二极管闭合直流反馈路径。 仅需要两条信号电缆用于偏置和读出。 显示英文摘要

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.
