We have reported the results of the interaction between the geomagnetic field and the development of atmospheric electron cascades as manifested by the distortion of the atmospheric Cˇerenkov signal. We will summarize these effects and describe our initial attempt to remove this distortion for those cases where the cascade develops perpendicular to a strong (>0.35 G) field and so enhance the hadron rejection procedures of gamma ray telescopes. © 2000 American Institute of Physics.

    The regime of excitation of subnanosecond high-power microwave pulses has been studied in a Cherenkov device with an extended periodic slow-wave structure, using an electron beam from a compact pulsed high-current electron accelerator (290 keV, 2.3 kA, 1 ns). Conditions are established for which...
