ASYM: A program to examine fission fragment mass asymmetry in hemispherical chambers

Title of program: ASYM
Catalogue Id: AADD_v1_0

Nature of problem
The program ASYM was written to assist in the design of a fission chamber for an experiment to measure delayed neutron spectra following fission of U-235. Fission takes place in a U-235 lined hemispherical fission chamber. Fission fragments emitted from the infinitely thick foil are trapped by helium gas in the chamber and are transferred to a counting area by a helium-jet system. To avoid a possible distortion in the spectra one would like fragments fo all masses to be stopped with equal probab ...

问题本质
本程序ASYM专为辅助设计裂变室而编写，用于开展铀-235（U-235）裂变后缓发中子能谱测量实验。该实验所用的半球形裂变室内壁镀有U-235涂层，无限厚靶箔产生的裂变碎片会被室内氦气俘获，并通过氦喷气输送系统传送至计数区域。为避免能谱出现潜在畸变，需确保所有质量数的裂变碎片均以同等概率被阻止……
