A PROGRAMMABLE LOW ENERGY ELECTRON DIFFRACTION DEVICE.

Abstract

A LEED device of the Faraday cage type has been constructed which is capable of being programmed to collecg intensity data at predetermined colatitude and azimuth angles. The range of angles which can be programmed is 0 degrees to 360 degrees in azimuth and 0 degrees to 80 degrees in colatitude. By using a metal chamber, ruggedness and simplicity in construction is achieved. The device is flexible enough to allow for an increase in automation by using punch card type inputs and to allow for a simple modification to a display device. Use of rotary motion feedthroughs permits firm control over motion of the sample and collector. (Author)
