Abstract

A FEM-oscillator with a reversed guide magnetic field and a Bragg resonator as a RF radiation source for collider applications was studied. The configuration with a step of the corrugation phase is proved to be advantageous. It possesses such features as a high efficiency, precise tunability of the operating frequency and a narrow spectral band. It is demonstrated experimentally that such an oscillator is capable of operating at frequencies of ~30 GHz in single-mode regime with the frequency tuning in interval up to 6%. Frequency and spectrum measurements have been performed with precision of ~0.1%.

Abstract

Results of theoretical and experimental studies of the microwave radiation sources on the base of the induction linac LIU-3000 (JINR, Dubna) are presented. In particular, a FEM-oscillator with the reversed guide magnetic field and Bragg resonator as well as an electron beam buncher in the two-beam accelerator (TBA) driver was studied.

Author

Abubakirov, E.B., Botvinnik, I.E., Bratman, V.L., Denisov, G.G., Gubanov, V.P., Kazacha, V.I., Korovin, S.D., Krasnykh, A.K., Ofizerov, M.M., Perel'stein, E.A., Polevin, S.D., Rostov, V.V., Sidorov, A.I., Smorgonsky, A.V., and Vinogradov, D.V.

Abstract

Radiation with output power up to 100 MW at wavelength 8 mm, at gain 44 dB and efficiency 11% was obtained in TWT with a relativistic electron beam. In a sectioned generator BWO-twistron, output power was 500 MW at wavelength 10 mm at efficiency 20%. [ABSTRACT FROM PUBLISHER]

6. Linear induction accelerator of the hollow electron beam.

Author

Arkhipov, O.V., Bobyleva, L.V., Brudanin, V.B., Kazacha, V.I., Konnov, G.I., Krasnyh, A.K., Kuznetsov, I.V., Nikitsky, A.Yu., Perelstein, E.A., Sidorov, A.I., Dvornikov, V.A., and Markov, V.N.

Abstract

Short description of the main systems of the holow electron beam linear induction accelerator (LIA) is given. The main characteristic features of the accelerator are; homogeneous solenoidal, pulse guiding magnetic field with strength up to 1.5 T in aperture 120 mm, high beam energy gain 10 keV/cm and beam current up to 1.5 kA; the lack of drift section between the electron sourse and induction system; the use in modulator of one thyratron and three stages of power compression providing power 7.5 GW with pulse duration 60 ns on the load 0.75 Ohm. The LIA characteristics, its possibilities, the measurement procedure of LIA and beam parameters in on-line regime are presented. [ABSTRACT FROM PUBLISHER]
