We describe main parameters and operational experience with new generation of electron accelerators for radiography and cargo inspection developed with participation of scientists, engineers and technologists from Lomonosov Moscow State University and "Research and Production Enterprise "Toriy". Two accelerators are described: accelerator for radiography UELR-8-2D with beam energy regulated in the range 3-8 MeV and dose rate from 0.5 to 15 Gy/min and accelerator for cargo inspection UELR-6-1-D-4-01 with pulse to pulse energy switching between 3.5 and 6 MeV, with repetition rate 400 Hz and dose rate 4 Gy/min. Both accelerators use klystron as an RF source, which is fed by solid state modulator.

Based on "open technologies" approach to design of control systems for radiography and cargo inspection electron RF accelerators constructed at Laboratory of Electron Accelerators MSU is described. The control system consists of a number of specialized controllers each responsible for separate accelerator subsystem connected via Ethernet interface and Modbus/TCP protocol with control computer which in turn is connected with control panel computer, modulator, power supplies etc. each having its own digital interface. Each controller contains one or several special boards conditioning external analogue and discrete signals and universal microcontroller part providing controller operation and network connection. Both control computer and control panel computer are based on BlueShark SOM (System on a Module) amd run Linux operating system. Custom SCADA-like system has been developed to provide proper accelerator operation and operator interface with support for different levels of access to accelerator parameters.

The results of calculation and optimization of pulsed linear accelerator with magnetic mirror on the beam energy, adjustable in the range of 20 - 45 MeV, designed for explosives detection and other applications are presented. The accelerator consists of an electron gun with an off-axis placed cathode with a beam hole on axis; of about 1.6 m long section of standing wave bi-periodic accelerating structure, operating at 2856 MHz, which is optimized to achieve the capture coefficient of more than 50% and of the energy spectrum width of about 2%; of a movable dispersion free magnetic mirror made with rare earth permanent magnet material. Accelerator provides acceleration of the beam with a pulse current of 100 mA to an energy of 45 MeV with RF power consumption less than 10 MW.
