PATENTANSPRÜCHE:PATENT CLAIMS: 1. Einrichtung zum Abbilden von Gegenständen mit Hilfe von Elektronenstrahlen, dadurch gekennzeichnet, daß der Elektronenstrahl durch in seiner Längsrichtung wirkende elektrostatische Felder beeinflußt ist derart, daß er in den verschiedenen Abschnitten des Strahlenganges eine andere, an der jeweiligen Stelle erwünschte Geschwindigkeit hat.1. Device for imaging objects with the aid of electron beams, thereby characterized in that the electron beam by acting in its longitudinal direction electrostatic Fields is influenced in such a way that there is one in the various sections of the beam path has a different speed that is desired at the respective point. 2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der abzubildende Gegenstand einem Elektronenstrahl geringer Geschwindigkeit ausgesetzt und die Geschwindigkeit im weiteren Verlauf des Strahlenganges durch in Riehrung des Strahles wirkende elektrostatische Beschleunigungsfelder gesteigert wird.2. Device according to claim 1, characterized in that that the object to be imaged is exposed to a low speed electron beam and the speed in the further Course of the beam path through electrostatic acceleration fields acting in the direction of the beam is increased. 3. Einrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnetj daß der Elektronenstrahl vor seinem Durchtritt durch den abzubildenden Gegenstand durch ein in Längsrichtung des Strahles wirkendes Verzögerungsfeld verlangsamt wird.3. Device according to claim 1 or 2, characterized in that the electron beam before it passes through the object to be imaged through a longitudinal direction of the Beam acting deceleration field is slowed down.
