Systems with Superconducting Lenses,ation, although the Glaser value of . in the bell-shaped field approximation corresponds to . = 2.1. But since the magnification should be controlled with the intermediate and projector lenses, the strong hysteresis in the shielding lens is very inconvenient and thus only iron-circuit lenses have been used up to now for further magnification.

Historical Survey, Laue colloquium, after the presentation of Meissner’s paper on field repulsion in superconductors. Because the superconductors known at that time exhibited relatively low critical temperatures and small critical current densities at high fields, the problem was not further pursued. After the discov

Basic Principles of Electron Optics,l transmission electron microscope is sketched in Figure 2.1. The electrons emitted from the cathode are first accelerated in a system of electrostatic lenses. The beam then enters the condenser system, which adjusts the illuminated area of the specimen. The specimen is situated somewhat above the c

Lens Design and Testing, axial field measurements were usually carried out with low-temperature Hall probes, magnetoresistance probes, or probe coils. In one case the field distribution in the whole lens was determined from a model in an electrolytic tank (Dietrich and Weyl, 1968). Yet the normal procedure for obtaining th

Since the magnification should be a maximum for a given column length, the lens strength with the smallest asymptotic focal length should be used. This leads to . ≈ 1

magnetic fields, a replacement of the conventional, i.e .. nonsuperconducting, electron optical parts, is worth considering if the outstanding magnetic properties of superconductors can improve the systems. However, the use of superconductors demands complicated cryogenic techniques and this, of cou
