This paper introduces a method to adjust the gap distance of nanosecond gas switch from outside when it is filled with high pressure gas. By using a two-stage planetary gear train and a pinion-and-rack device the gap between the electrodes can be linearly adjusted. The adjusting precision is 0.05 mm and adjustment range is 0 to 10 mm. The sealing of the insulator ring, rotation axle and outside conductors is designed. The performance of the rotation axle is pretty well under 12MPa gas pressure, air leakage not found. Experimental study on switch discharging is carried out by using a high voltage nanosecond pulse generator. The results show the output voltage of the pulse can reach 600kV by adjusting the switch gap. The rise-time of the pulse can be shortened form 3.5ns to 1ns.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
