[en] The magnicon belongs to the class of high power RF sources, where a modulation is provided by the beam circular deflection and it is an advanced version of a gyrocon. The first magnicon has been built and tested in Novosibirsk in the middle of the 80's. The power of 2.6 MW has been obtained for the frequency 91.5 MHz and pulse duration 30 mcsec. The electron efficiency has been 85%. Good results obtained during investigations show that the magnicon can be an adequate RF source for the next generation of accelerators, especially for future linear colliders and accelerators for transmutation of nuclear waste. The magnicon conception described in the present paper allows to increase significantly the beam perveance, compared with the first magnicon, and to achieve the pulse power of tens and hundreds megawatts at the beam voltage not greater than 400-600 kV. The device is an amplifer working in frequency doubling mode and is a prototype of a RF source for linear colliders with high acceleration gradient. The magnicon is designed for an output power of 50 MW, an operating frequency of 7 GHz and a pulse duration of 2 mcsec

[en] A prototype magnicon designed for the RF source of a ''normal'' conducting electron--positron linear collider is described. Its main operation parameters are a power output of 50 MW, at a frequency of 7 GHz and with a pulse duration of 2 μsec. The described magnicon is an amplifier operating in frequency doubling mode

[en] The subject of the report is the problem of the technical feasibility of fast electron cooling in the energy range between 0.8 and 14.5 GeV. It is very useful for one of the major objectives of the GSI and COSY future plans. For the realization of the cooler device BINP team proposes the design that is like the conventional and elaborated for the low energy cooling (up to 300 keV). The main features of this design are the accelerating tube immersed in the magnetic field along the whole length and the strong magnetic field in the cooling section. The physics of electron cooling is based on the idea of the fast magnetized cooling. The cooling force at strong magnet field was measured at many experiments and can be surely estimated. The magnetized cooling rate enables to obtain the required beam parameters, eliminate the beam heating due to intrabeam scattering, fluctuations of ionization energy losses and multiple scattering in the internal target
