Description

The invention relates to an arrangement for converting microwave energy into electrical energy Electricity energy with a cathode ray tube, Velchc a coupling element for coupling in the microwave energy on the electron beam and a device (deceleration electrode) for decelerating of the electron beam acted upon by the microwave energy.

Work has been going on for some time on the problem of wireless energy transmission with the help of To achieve microwaves. The wireless transmission of large powers is particularly important for energy supply of missiles from essential bcdcuhing. Weilerhin an energy transfer by means of microwaves can also on earth over large Routes become meaningful.

In doing so, the electrons beam of the Klvsirons with the microwave oven modulated and then by braking iL Electron beam part of the Miknmclienlcisimi; transformed into cileophytesy.

The understanding is based on the task, a. Arrangement for converting microwave energy in (ileicheneruie with the help of a cathode ray tube to create the efficiency of which is not due to a longitudinal velocity distribution of the Beam electrons is restricted. In order to achieve this object, the arrangement mentioned at the outset is used in the case of an arrangement Art proposed according to a first embodiment of the invention that the coupling part dei Cathode ray tube in the presence of one which runs longitudinally in the direction of the electron beam homogeneous magnetic field is a coupler for a fast cyclotron wave on which a reversal follows the magnetic strength direction in such a way that the cyclotron wave turns into a Converts synchronous shaft. The cyclotron wave coupler can advantageously be a Cuccia coupler be with resonance property.

In a further development of the invention it is provided that the cyclotron wave coupler consists of a waveguide which is transverse to the electron beam axis Directional electric field leads, which is circularly polarized.

An arrangement according to the invention has the advantage that essentially no longitudinal velocity distribution occurs when the microwave energy is coupled into the electron beam. The deflection given to the electron beam from the beam axis is either expressed directly in a uniform increase in the drift speed of the electrons or is converted into a corresponding increase in speed. As a result, all electrons of the electron beam can be braked evenly, so that all of the energy carried by the beam is recovered in the form of direct current power. The efficiency of the arrangement depends essentially only on the losses in the coupler and can therefore reach Wcric of over ⁽ ) () "0.

An electron beam that moves in a / ur electron beam direction longitudinal stationary homogeneous magnetic field is known with so-called Transverse waves are modulated when a high frequency field directed transversely to the electron beam axis acts on the electron beam. The cathode ray tube of an arrangement according to the invention can work with such transversal waves, initially advantageously in the electron beam a rapid cyclotron wave is generated, which is caused by a reversal of the magnetic strength direction in a synchronous shaft is converted.

Instead of modulation with the known transverse waves, an arrangement according to the invention after a second form of quotation too
