Van Aken, R.H. (author)This thesis has discussed two electron microscopy applications that make use of ultra-thin foils: the tunnel junction emitter and the low-energy foil corrector. Both applications have in common that the electron beam is sent through the thin foil at low energy. Part of the electrons will scatter in the foil, thus causing a reduction of the...doctoral thesis 2005
