Abstract
In one aspect, the present invention provides a method of generating an electron beam in a transmission electron microscopy device. The method includes: generating an electron pulse [] by a pulsed electron source [], accelerating the electron pulse in a first resonant microwave cavity [], passing the accelerated electron pulse through a drift space [], and correcting the energy spread of the accelerated electron pulse in a second resonant microwave cavity [] by operating it out of phase by 90 degrees from the first resonant cavity [
