Improved resonance in microtrons by orbit shaping
V B Asgekar R K Bhalla M R Bhiday V N Bhoraskar B S Raye
Microtron electron accelerators generally show a 50% reduction of the injected beam in the first orbits. A modification of the race-track magnet system is proposed in this paper to reduce the beam losses. Calculations of the phases of electrons at the microwave cavity yield exact shapes of different orbits required for resonance in a split magnet system. Introduction of small sector magnets in the field-free space provides a feasible method for obtaining the calculated orbit shapes.

Single-cavity 8 MeV race-track microtron
V B Asgekar R K Bhalla B S Raye M R Bhiday V N Bhoraskar
This paper describes the operational details of the single-cavity race track microtron of this laboratory. The machine is capable of providing electrons of 8 MeV energy at 1 mA peak current. Important parameters of the machine and beam handling system are studied and the results are reported.
