Popis:	Until now there have been only a few attempts to use many scattering angles simultaneously in triple-axis spectrometry with neutrons. We present a novel Multi-Analyzer Detector (MAD) unit for a Triple-Axis Spectrometer (TAS) set up at the Forschungsreaktor Munchen (FRM). The layout is based on the principle of monochromatic defocusing. Up to 61 analyzers are mounted around the sample in the constant final energy mode. This arrangement supplies the flexibility of a TAS with a multi-channel analyzer capacity similar to a Time-of-Flight Spectrometer. The gain in measurement time can be more than an order of magnitude.
