EXPERIMENTAL FACILITIES AT THE 2 MV VAN DE GRAAFF ACCELERATOR
Two beamlines are installed at the 2 MeV van de Graaff accelerator:
GONNYGONNY consists of a large scattering chamber with a computer-controlled 4- axis - goniometer for standard RBS and NRA analyses incl. channeling. Samples can be introduced with a simple load lock system. The data acquisition accepts up to eight detectors simultanously. One detector is mounted on a precision rotational stage and can be used for double alignement measurements.
Heating or cooling stages are not provided at this goniometer.
GOLFThe second beamline is terminated with a standard 500 mm diam. scattering chamber.
An accurate, computer - controlled three-axis goniometer is utilized for channeling experiments and for He – ERDA of hydrogen.
