Popis: The filter assembly which has recently been installed in the HBll beam tube of the High Flux Reactor (HFR) at Petten has been the culmination of two years of intensive activity. This has included a lengthy series of calculations to optimise the facility for BNCT. Previous work1 had shown the effectiveness of a combination of “spectrum shifter” and filter in producing an epithermal neutron beam of the required characteristics. Here a “spectrum shifter” is a device, placed close to the source, which moderates unwanted high energy neutrons to lower energies within the beam. In contrast a “filter” is positioned some distance from the source and simply removes unwanted neutrons from the beam.
