The schematic diagram of the lasing experiment for this sample is shown in Fig. 3A. WebWorking: Stream of electrons are produced by the electron gun and these primary electrons are accelerated by the grid and anode. These accelerated primary electrons are made to be incident on the sample through condensing lenses and scanning coil. These high speed primary electrons on falling over the sample produces low energy secondary electrons. great white hype full movie
