    Abstract: The invention relates to a drift tube accelerator (1) for the acceleration of ion packets in ion beam acceleration systems, wherein a housing (2) consists of a longitudinally divided three-part vacuum tank (3) having a central unit (4) and a lower half-shell (3) comprising a structured lower steel block (15) and an upper half-shell (6) comprising a structured upper steel block (19). (The cavity arranged between the central unit (4) and the structured steel blocks (15, 19) has at least two acceleration regions (24, 25), between which there is arranged a magnetic focussing device (17), which focuses the ion beam from one region (24) to the next region (25).) The drift tube accelerator (1) according to the invention has such a stable and massive structure that it requires no external supporting aids of any kind in order to obtain alignment, which is reliable and accurate to a few micrometers, of the acceleration components within the drift tube accelerator (1) with respect to the longitudinal axis (7) of ion beam guidance of the central unit (4). The massive structure of the drift tube accelerator (1) according to the invention can be used in general for any linear accelerator.

    Abstract: A multi-stage microwave gyrotwystron amplifier is disclosed having two or more stages comprising rectangular cavities to facilitate tuning. The first two stages comprise rectangular tuneable cavities that are oriented orthogonal to each other which produces a homogeneously modulated electron beam that is directed to a cylindrical output cavity which increases its power output as compared to prior art devices havig an output cylindrical cavity excited with a non-homogeneously modulated electron beam.

    Abstract: Two or more signal interaction structures (16,18), which may be klystron or traveling wave structures (32,50), are axially disposed in series between an electron gun (12) and a collector (14) for selectively velocity modulating an electron beam (20) generated by the gun (12) with a microwave input signal (IN1,IN2) and extracting a resulting amplified microwave output signal (OUT1,OUT2) from the beam (20). The interaction structures (16,18) are designed to operate in different frequency bands, for example the X and Ku bands, with only one of the structures (16,18) having an input signal (IN1,IN2) applied thereto at any given time. The interaction structures (16,18) are further designed such that the structures (16,18) which are not being used do not affect the structure (16,18) which is being used.

    Abstract: A self focusing linear charged particle accelerating structure is provided which avoids the radial defocusing effect of the particle beam, more particularly at the outlet of a first accelerating cavity which this structure comprises. Said first accelerating cavity comprises an inlet face and an outlet face which are spaced apart by a distance formed by an accelerating length plus an additional length intended to delay the arrival of the particles at said outlet face.

    Abstract: A klystron is provided for supplying power with optimum efficiency across a variable impedance load. To attain this result, the field in the output cavity of a klystron is detected by a probe. This field supplies the image of the voltage at the terminals of the interaction gap. The signal supplied by the probe is used for adjusting the amplitude of the ultra-high frequency voltage applied to the input cavity so that the voltage of the terminals of the interaction gap remains less than the tolerable maximum whatever the ratio of standing waves reflected back by the output device.
