Abstract

A detailed analysis of the mathematical model of the adiabatic calorimeter is presented. An unsteady solution of the corresponding heat equation is presented and its features are considered. Two definitions of the response time of an adiabatic calorimeter operating, generally speaking, in a nonstationary mode are proposed. The question of determining the sensitivity of an adiabatic calorimeter is considered. Based on these definitions, a solution to the problem of the optimal choice of the material of the receiving plate in terms of the ratio of sensitivity and response time is proposed. Comparisons are made with some published experimental and theoretical results. The results obtained in this study can be used in the development and design of calorimetric systems for the diagnostics of beams of fast neutral particles.

动态模式下粒子束能量流绝热量热仪运行的数学模型

摘要

对绝热热量计的数学模型进行了详细分析。给出了相应热方程的非定常解并考虑了其特征。提出了两种定义，一般来说，在非平稳模式下运行的绝热热量计的响应时间。考虑确定绝热热量计灵敏度的问题。基于这些定义，提出了接收板材料在灵敏度与响应时间之比方面的最优选择问题的解决方案。与一些已发表的实验和理论结果进行了比较。本研究中获得的结果可用于开发和设计用于诊断快速中性粒子束的量热系统。
