Calorimetric experiments have been performed to analyze different thick targets of natU, C, Pb material, irradiated by 660 MeV protons at the Phasotron accelerator facility, Joint Institute for Nuclear Research (JINR) in Dubna, Russia. The method of online temperature measurement has been compared with MCNPX 2.7.0 simulation and selected with Ansys Transient Thermal Simulation to compare measured temperature with the simulated one. Thermocouples type T and E have been used as a temperature probe. Many different positions have been measured for each target. Temperature results are following very well the processes inside of the cylinders. Changes of heat deposition caused by drops of the proton beam intensity are displayed very well as a jagged line shown in almost every chart. Accurate temperature changing measurement is a very modest variation of how to observe inner macroscopic behavior online.

660 MeV质子辐照不同目标产生的热量

量热实验已经进行分析的不同厚靶NATU,C,Pb材料,在俄罗斯杜布纳联合核研究所(JINR)的Phasotron加速器设施中,由660 MeV质子辐照。在线温度测量方法已与MCNPX 2.7.0模拟进行了比较,并与Ansys Transient Thermal Simulation进行了比较,以将测量温度与模拟温度进行比较。T型和E型热电偶已用作温度探头。对于每个目标,已经测量了许多不同的位置。温度结果很好地遵循了气缸内部的过程。质子束强度下降引起的热沉积变化几乎在每个图表中都显示为锯齿状。准确的温度变化测量是如何在线观察内部宏观行为的非常适度的变化。
