The plasma energy content in the Uragan-3M torsatron was determined by means of diamagnetic measurements under the conditions of its radiofrequency (RF) generation and heating (at near ion-cyclotron frequencies) in the presence of bootstrap current. The balance of power under the fast heating of plasma was considered and used as a basis to estimate the radiofrequency power absorbed by the plasma in the confinement volume. The behavior of energy losses in the discharge period was calculated, and the effect of magnetic field fluctuations on the energy losses within a frequency range of 0.5–70 kHz was discussed.
