Abstract

A Philips 430ST high-resolution electron microscope has been converted for ultra-high-vacuum operation by substitution with a novel specimen chamber, which also incorporates a flexible chamber for specimen preparation and treatment, and additional pumping facilities. Key features of the design include a single-tilt specimen holder with in situ heating to 1200° C, and liquid-helium-cooled cryofingers above and below the sample. Initial operating experiences indicate that the microscope performance has not been compromised by the UHV conversion. However, selection of optimum imaging conditions is difficult for a clean crystalline material.
