	In the previously designed, calculated and tuned structure of the compact generator-cavity the beam dynamics for the different geometry options has been calculated. The influence of injected beam parameters to the output power value has been overviewed. Also the geometry of the beam tubes and couple coefficient between cavity and the output waveguide has been optimized to reach the maximum output power value.

TUPSA14	Mathematical Optimization Model of Longitudinal Beam Dynamics in Klystron-Type Buncher	controls, electron, bunching, experiment	66
	I.D. Rubtsova St. Petersburg State University, St. Petersburg, Russia
	The paper presents recurrent integral-differential beam evolution model. This model is convenient for mathematical description of specific dynamic processes with due account of particle interaction and electric fields excitation by moving beam. On the basis of this model the problem of beam dynamics optimization is formalized as trajectory ensemble control problem. Analytical expression for quality functional gradient is obtained. Theoretical results are applied for solving problem of beam dynamics optimization in klystron-type buncher.

	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.

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.
