	A race-track microtron with a few beam orbits can be an alternative to a standard electron linear accelerator in a number of applications in which high beam power is not needed, like radiation therapy, industrial radiography or cargo inspection. In these cases the advantages of race-track microtrons are low RF power consumption, and consequently low cost of the RF system, and a possibility of beam energy switch in a wide range by extracting the beam from different orbits. In the present work we describe the concept of a race-track microtron with pulse-to-pulse beam energy switch in the range from 3 MeV to 9 MeV. Special attention is given to the optimization of the end magnets of a new type which provide both the accelerating structure bypass and vertical beam focusing.

The hydraulic and thermal performance of the cooling 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 trans-fer coefficients at different sections of the RTM accelerating structure.

The hydraulic and thermal performance of the cooling 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 trans-fer coefficients at different sections of the RTM accelerating structure.
