In {sup 3}He-B at temperatures of the order of 0.1{Tc}, where the mean-free path of the excitations measures several hundreds of metres, the authors are able to perform experiments on fully ballistic quasiparticle beams. They describe the first direct production and detection of a quasiparticle beam in superfluid {sup 3}He with the use of a black-body radiator. The radiator may be used as a smoothly controllable continuous source and also as a bolometric detector, sensitive to a quasiparticle energy flux of order 100fW mm{sup {minus}2}. 1 ref., 2 figs.
