“…In storage-type calorimeters, the increase in the temperature of the working fluid is most often measured by the increase in the volume of the working fluid in the measuring capillary tube using resistance sensors [5] or capacity [6]. But the passage of electric current through water and its solutions leads to electrolysis and decomposition of water [7].…”

The paper presents the construction of a storage-type waveguide calorimeter designed to measure the energy of a sequence of short microwave pulses. The radiation is absorbed by water or ethanol, then the temperature increase is recorded by the LM 35 sensor. When using 14 cm3 of water, the energy measurement range is 3…88 J, and when using ethanol 1.3…40 J. The calorimeter is simple, cheap, and reliable.

This paper studies the coaxial relativistic backward wave oscillator (CRBWO) through analytical, numerical, and experimental methods. This new type of device is remarked by its high efficiency of more than 35%, which is predicted by the theoretical calculation and the numerical simulation and validated by experiment. The two primary hindrances preventing CRBWO from achieving the expected high efficiency, the poor coaxiality and the power capacity, are discussed in detail and some advanced methods are developed. The theoretical and numerical conclusions agree with the experiment results, which are obtained from the electric probe and the calorimeter simultaneously for each shot of CRBWO. Employing the electron beam pulse of the full width at half maximum 28 ns, a microwave pulse of the width about 20 ns is generated in the experiment; the power is 710 MW and the efficiency is higher than 33%.
