Analysis of the Current Loading of an Accelerating Field Beam From a Lue-200 Accelerator

The current loading of an accelerated electron beam in the accelerating fields of a LUE-200 linear accelerator of the IREN facility at the Joint Institute of Nuclear Research (Dubna) is discussed. The LUE-200 accelerator consists of two accelerating sections operating on a traveling wave at a frequency of 2856 MHz with the microwave power compression systems of the SLED type. The limits of the accelerated beam current values are determined for various pulse durations of the beam current and microwave power levels fed into the accelerating sections. The calculation results are compared with the measured data.
