ABSTRACT:
A sample loading device for loading samples into and unloading samples from an ultra high vacuum analysis chamber without the necessity to raise and lower pressure each time a sample loading or unloading is effected, is described. The sample is initially positioned in a chamber of comparatively small volume which can be rapidly and simply evacuated to a vacuum approximating that of the analysis chamber. A gate valve between the small volume chamber and the analysis chamber then is opened and the sample introduced to the analysis chamber by a simple rack-and-pinion mechanism. Fine positioning of the sample and release of the carrier from the insertion fork is achieved by external X- and Y-axis adjustments.
