项目摘要

We have studied on new approach of solid state detectors for X-ray photons. Especially we examined the cooled solid state detectors which have not yet been established. First of all ion-implanted Si PIN detectors, Josephson junction type detectors and micro-colorimeters were examined in collaboration with authorities of related fields. Refering this examination we decided that we were involved in study of the micro-calorimeter. This new detectors have several fundamental prolbems to be examined experimentally.(1) A reliable and handy cryostat system should be developed. We purchased a special desighed cryostat which works by means of a closed system of ^3He. This is useful for working surface of 0.3 K. We have examined basic properties of some kinds of solid material. Thus we have understood fundermental properties of solid material at very low temperature. (2) We also purchased some kinds of thermomitors for low temperature less than 1 K. We improved these to inspect fundamental properties such as heat capacity and thermal conductivity for calorimeters. (3) Finally we have obtained pulse signals from the calorimeter which is irradiated by -rays or X-rays.We have established basic concept of micro-calorimeters for X-ray photons. Therefore, we will develop the present result making a new type of thermisters in future.

研究了X射线光子固态探测器的新方法。特别是我们研究了尚未建立的冷却固体探测器。首先，与相关领域的权威机构合作，对离子注入硅PIN探测器、约瑟夫森结型探测器和微量比色计进行了检测。参考这项检查，我们决定我们参与研究的微量热计。这种新的探测器有几个基本问题需要实验检验。(1)应研制一种可靠、方便的低温恒温器系统。我们买了一个特殊设计的低温恒温器，它是通过一个封闭的^3He系统工作的。这对于0.3K的工作表面是有用的。我们已经研究了几种固体材料的基本性质。这样我们就了解了固体物质在极低温度下的基本性质。(2)我们还购买了几种温度低于1K的低温热敏电阻。我们改进了这些方法，以检查热量计的基本性能，如热容和热导率。(3)最后给出了X射线或γ射线照射量热计的脉冲信号，建立了X射线光子量热计的基本概念。因此，我们将在未来发展目前的结果，使一种新型的热敏电阻。
