Calculation of heat input to cryopumps by Monte Carlo method
- 1. Japan Atomic Energy Research Inst., Tokai, Ibaraki. Tokai Research Establishment
Description
A two-dimensional monte carlo calculation code was made for estimating the heat input to cryopumps for hydrogen. It calculates the following: (1) energy distribution and reflection efficiency of the backscattered particles from the beam dump, (2) molecular flow rate and energy distribution of the backscattered energetic particles through the chevron baffle, and (3) radiation transmissivity of the chevron baffle . For cryopumps of the neutral beam injection systems for JAERI's plasma feasibility experiment device JT-60, the heat input to the cryopanel due to backscattering and radiation was estimated with the code.
