Panel a: Dynamic spectrum of the oscillogram of the electric field shown in Fig. 2. The dashed line shows the time variation of the frequency 2/cc0, where / ce0 is the electron gyrofrequency at the center of the magnetic trap. The solid line shows the variation of the upper-hybrid resonance frequency/^ during plasma decay. The dash-and- dot lines show the spread in determination of the frequency f a allowing for the accuracy o f measuring the temperature o f the background plasma (about 30%). Panel b\ current of the energetic electrons precipitating from the trap. 66
