A coupling-out window for linearly polarized high-power microwaves exhibits at least one plate transparent to microwaves and cooling fins. The cooling fins are situated together with the plate in a plate plane and are aligned perpendicular to a direction of polarization of the microwaves. They are in heat-conducting and pressure-locking contact with the plate.

In an arrangement for measuring the energy of a microwave pulse a container (2) is placed on the end of a waveguide (1). In container (2) there is an absorption liquid (3) with a given heat content, which absorbs the energy of the irradiated microwave pulse. The increase of the heat content thus caused which corresponds to the energy of the microwave pulse is determined by the volume expansion of the absorption liquid (3). For this purpose container (2) is connected to a capillary (4). Preferably container (2) is covered with a reflection layer (12). Further, it is additionally connected to a balancing volume (5) and is cooled with a cooling coil (14).

A flange connection for round waveguides achieves a high-accuracy coaxiality of two round mutually adjoining waveguides (1a, 1b) by means of a radially elastic centering ring (3). The flange connection comprises two independent flange rings (2a, 2b) which are in each case attached to one end of the waveguides (1a, 1b), in which arrangement they are attached so as to be undisplaceable in the axial direction for a construction of the flange connection but to be freely rotatable around the respective waveguide. According to a preferred embodiment of the invention, the flange rings (2a, 2b) are constructed in such a manner that the flange connection can be joined in the manner of a bayonet lock.
