Description

The paper presents the results of the recent fast electron measurements performed by means of a new measuring head, which was equipped with two Cherenkov-type detectors made of diamonds coated with appropriate absorption filters. The high light efficiency of those detectors enabled a high temporal resolution and a good signal-to-noise ratio to be achieved. The obtained results made it possible to determine the conditions of the runaway electrons' appearance and to study their correlations with hard x-rays. (paper)
