A 100 kv scanning transmission microscope has been built. Briefly, the design is as follows: The electron gun consists of a field emission point and a 3 cm Butler gun. The beam has a crossover outside the gun and is collimated by a condenser lens.The parallel beam passes through a defining aperture and is focused by the objective lens onto the specimen. The elastic electrons are detected by two annular detectors, each subtending a different angle, and the unscattered and inelastic electrons are collected by a third detector. The spectrometer that will separate the inelastic and unscattered electrons has not yet been built.The lens current supplies are stable to within one part per million per hour and have been described elsewhere.The high voltage is also stable to 1 ppm/hr. It consists of the raw supply from a 100 kv Spellman power supply controlled by an external reference voltage, high voltage divider, and error amplifier.

A high voltage power supply has been constructed for use with the ORNL Superconducting Microscope described elsewhere in these proceedings. A simplified schematic diagram of the system is shown in Figure 1. The regulator circuit employs a “bouncer” with a cathode-follower output. This configuration results in a low output impedance and the bouncer can thus drive a load capacitance over a wider bandwidth than the conventional common-cathode circuit. The voltage divider for the regulator is a dual unit originally developed to determine the stability of resistive high-voltage dividers. A dual capacitive divider is an integral part of the voltage divider as shown in Figure 1. The dual units have proven to be very useful in practice since one divider may be used in the regulator while the second is used to monitor the noise present on the high voltage. Mercury cells are used as reference elements in the regulator. Wide-band noise on the output is about one ppm at present. Modifications are now under way to eliminate at least two of the known sources of noise in the system.
