提出了一种新的电离辐射探测方法。在检测器介质中产生的电离量通过在施加电压下带电载流子在器件上漂移时产生的热量来测量。所产生的能量可以比辐射本身所沉积的能量大几个数量级。与简单的量热粒子探测器相比，对于相同的能量阈值，可以实现探测器质量的显著增加。可以获得足以进行单载波检测的灵敏度水平。的工作原理已被证明与在1.8 K的温度下操作的实验设备，并提高性能，预计在较低的温度。
A new approach to ionizing radiation detection is proposed. The amount of ionization produced in a detector medium is measured by the heat generated as the charged carriers are drifted across the device under an applied voltage. The amount of energy generated can be orders of magnitude larger than that deposited by the radiation itself. A dramatic increase in detector mass can be achieved compared to simple calorimetric particle detectors for equivalent energy thresholds. It is possible to obtain a sensitivity level sufficient for single‐carrier detection. The principle of operation has been demonstrated with an experimental device operated at a temperature of 1.8 K, and improved performance is expected at lower temperatures.
