	New data on the development and experimental investigation of the RF accelerator based on the 9-cavities parallel-coupled accelerating structure that is equipped with a high-frequency grid-controlled electron gun are presented. Accelerating structure, injection system and focusing system are improved. Previously observed second emission resonant discharge - multipactor is suppressed by increasing the field amplitude in the structure first cavity and using the protector. The parameters of the accelerated beam close to the design ones, i.e. electron energy up to 8 MeV, capture to the acceleration mode up to 100%, were received. Capture is provided by the RF electron focusing of the microwave field structure with usage of the magnetic focusing system based on permanent magnets and RF grid control in the electron gun.

TUPSA008	Gradient Limitations for RF Accelerator on Parallel-Coupled Structure	225
	Y.D. Chernousov ICKC, Novosibirsk, Russia I.V. Shebolaev ICKC SB RAS, Novosibirsk, Russia
	RF breakdown is the main gradient limitation for RF accelerator. It is believed that all the known ways to increase the accelerating gradient have been already investigated. These are increase in the frequency of the accelerating field, reduction in the pulse duration, the optimization of cavities form, selection of operating surface materials, preparation and training of accelerating structures. In this paper, we discuss the possibility of increasing the accelerating gradient due to the circuit design, i.e., the use of the parallel-coupled accelerating structure.

RF breakdown is the main gradient limitation for RF accelerator. It is believed that all the known ways to increase the accelerating gradient have been already investigated. These are increase in the frequency of the accelerating field, reduction in the pulse duration, the optimization of cavities form, selection of operating surface materials, preparation and training of accelerating structures. In this paper, we discuss the possibility of increasing the accelerating gradient due to the circuit design, i.e., the use of the parallel-coupled accelerating structure.
