Abstract
We describe the beam characteristics of the first ballistic supermirror neutron guide H113 that feeds the neutron user facility for particle physics PF1B of the Institute Laue-Langevin, Grenoble (ILL). At present, the neutron capture flux density of H113 at its 20×6 cm2 exit window is Φ C = 1.35 × 1 0 10 cm - 2 s - 1 , and will soon be raised to above 2×1010 cm−2 s−1. Beam divergence is no larger than beam divergence from a conventional Ni-coated guide. A model is developed that permits rapid calculation of beam profiles and absolute event rates from such a beam. We propose a procedure that permits inter-comparability of the main features of beams emitted from ballistic or conventional neutron guides.
