	CW resonance accelerator with high average power electron beam is developed at RFNC-VNIIEF. Electron energy range is varied from 1.5 to 7.5 MeV and average beam current is up to 40 mA. Electrons obtain the required energy by several passing of coaxial half-wave accelerating cavity. In this paper we present the results of electron beam dynamics simulation during its acceleration and transportation. The operating parameters of RF system, beam optics and bending magnets are determined. These parameters permit to obtain output beam with minimal current losses on each accelerating stage. As a result of carried out tests we obtained 7.5 MeV electron beam after five passes of accelerating cavity. The electron energy spectrum, average beam current, transverse beam dimensions were determined on each accelerating stage. Common beam current loss is under 10 %.

	There arises a need for measuring the output electron energy in the on-line mode during set-up, adjustment or operation of an accelerator. For this purpose a system is developed, allowing an on-line control of an accelerated electron energy spectrum simultaneously with average current measurement. This system is meant for reconstruction of the energy spectrum of accelerated electrons in the energy range from 1 up to 10 MeV at the average beam current from 20 up to 150 µA. The system is based on the method of absorbing filters and consists of an assembly, absorbing an accelerated electron beam, and a measuring system. The absorption assembly represents a set of insulated from each other electro-conducting plates of dimension 100x100 mm and thickness from 0.15 up to 1 mm with an air gap between plates 2 mm. The operation involves development, manufacture and calculation of electron beam transmission through the absorption assembly, development and manufacture of hardware for automated measuring of absorbed charges in the assembly elements, development of a master computer program as well as a program of energy spectrum reconstruction, using measured and calculated data, testing of the energy on-line control system on the LU-10-20 linear resonance electron accelerator. Tests of the developed sample on the electron accelerator have proved the applicability of the system to control the electron beam energy in the real-time mode.
