Research outputpeer-review


Large gold-siliconsurface-barrier detectors were constructed for the detection of fission fragments and energetic a-particles (30MeV). In the construction techniques the emphasis is put on the large surface, resolution and sturdy construction. Careful surface treatment of the Silicon wafer proved to be Important for the final resolution. The use of delicate wires to make contact to the inversion layer was avoided. To illustrate the performance of the detectors, single fragment
kinetic energy spectra and sum spectra ( + E21 are shown, for the fission of u235 with thermal neutrons. Also the performance for a-particle detection is illustrated.
