SIMPLE PULSE MICROWAVE WAVEGUIDE CALORIMETER WITH TEMPERATURE SENSOR LM 35
Year: 2023

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.
