Extreme FESEM

ESEM (Danilotos 1990, 1997) is being used for in situ studies of polymers to understand a variety of surface effects in the presence of water such as swelling [Pg.73]

Electron emitter (W, W-Th02, W-La203, porous W). Other elements are better emitters, but W has an extremely low vapor pressure and can be used at higher temperatures (it keeps the filament free of gas contamination, which would decrease emission). Therefore, W is practically the only material used in this field. Timgsten can be used as cold (field emission) and as hot emitter (thermionic emission). The principles are explained in Section 1.2.7. Field emission cathodes are used in field emission electron microscopy (FESEM). Examples of thermionic emission are manifold ... [Pg.289]
