- Аннотация: With the aim of optimization, numerical simulations of the cooling and vacuum systems of a compact 12 MeV race-track microtron (RTM) which is under construction at the Technical University of Catalonia have been carried out. The hydraulic and thermal performance of the cool-ing system for various flow rates has been studied using the Computational Fluid Dynamics (CFD) software. A CFD model, previously validated with experimental pressure loss results, has permitted to simulate the cooling fluid temperature, inner wall temperatures and heat transfer coefficients at different sections of the RTM accelerating structure. Conclusions concerning the current design and its possible optimization are discussed. Simulations of the RTM high vacuum conditions have been performed using the Monte-Carlo simulation package Molflow+. The pressure in the vacuum chamber, pumping tube conductance and maximum allowed throughput have been calculated. Also results of the vacuum chamber pumping out sessions are reported.
