Abstract
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).
Claims9
An arrangement for measuring of pulse energy of a microwave pulse, comprising:
- a container filled with an absorption liquid;
- said container having at least one transparent HF window for microwaves;
- a capillary containing a highly liquid medium and connected to the container for measuring the volume expansion of the absorption liquid;
- wherein:
- a liquid rise in the capillary is indicated by said highly liquid medium, which is less dense than the absorption medium and which is poured onto the absorption medium.
