In a direct electron detector, backscattering of electrons into the detector volume from below the sensor is prevented. In some embodiments, an empty space is maintained below the sensor. In other embodiments, a structure below the sensor includes geometry, such as multiple high aspects ratio channels, either extending to or from the sensor to trap electrons, or a structure of angled surfaces to deflect the electrons that pass through the sensor.
