Abstract :
A four-axis vacuum goniometer for application in ion beam channeling is described. It has three axis of rotation and one translation stage for movement in horizontal direction. The error reproducibility has been found to be less than one step. The microprocessor controlled goniometer is driven by vacuum stepper motors that are located within the vacuum chamber. The control of four stepper motors may be executed either from the front panel of control unit or from the host computer across the serial port. The sample can be heated up to 900°C
