Abstract: The pulsed cathode luminescence of spodumene and yttrium-aluminum garnet crystals activated by Mn$^{2+}$ and Nd$^{3+}$ ions, respectively, is studied. Luminescence is excited by the irradiation of the crystals by electron beams with a duration of 0.1, 0.25, 0.65, and 10 ns and a current density of $\sim$40 and 100 A/cm$^2$ at an electron energy of $\sim$200 keV. A decrease in the electron beam duration to several tenths of a nanosecond is shown not to cause substantial changes in the excitation mechanisms of pulsed cathode luminescence and its spectrum.
