The NSD neutron generator was recently installed in a Neutron Activation Analysis laboratory. (The Hochschule Mannheim, University of Applied Sciences, Department of Chemical Engineering and Process Engineering, Prof. Dr. Erich Fosshag). The neutron generator will be used for Neutron Activation Analysis and PGNAA work.

Lead of 2 mm thickness will cut the Bremsstrahlen x-ray radiation to the detector. A HpGe detector is shown. The red tape marks the position of the electrode within the reaction chamber. A large BGO detector, that was shielded with lead, has also been used in proximity to the neutron generator.

An improvised moderator and collimator was assembled from available paraffin blocks. Lead shielding surrounds the NSD-NG and the detector(s). This set-up was used to obtain gamma spectra of various reference elements. The customer is switching from the Californium neutron source to the NSD neutron generator.
