The special calorimeter for measuring total energy of HF-wakefields excited in plasma or dielectric by relativistic electron bunches has been elaborated. Simple by design calorimeter operates in the energy range from 0.02 J up to 780 J. Water is used as an absorbing material. For measuring irradiated water volume change the capacitive ferroceramic sensor was applied. Sensor sensitivity is 8.7 pF/J that two orders exceeds sensitivity of capacitor-sensor used in our experiments before. The calorimeter is not sensitive to nonuniformity of radiation field, and its response on HFradiation is high enough. Calorimeter design allows along with measuring radiation energy simultaneously controlling the current of bunches sequence.
