Electron beam bom-bards DRZ uorescent screen (covered with 14 mAl lm to block stray light) emitting uorescence, which is detected by an EM-CCD to get electron beam spot image. When move in magnet, the electron beam energy spectrum is recorded by

2) All these techniques are similar in that an ion beam is generated by a type of plasmatron or an alkali metal. The beam is then focused at a sample and used to erode and sputter the target area. This sputtered and ionized material is then carried into the spectrometer by a counter gas.

Time-of-Flight Mass Spectrometry - Agilent

The more parallel the ion beam, the higher the resolving power that can be achieved. After the ions have been shaped into a parallel beam, they pass through a pair of slits into the third and last vacuum stage. where the time-of-flight mass analysis takes place. Because the mass of each ion is assigned based on its flight time, the
