BS>A prolate spheroidal field beta -spectrometer is described in which the source and detector are located on the same side of the focal ring slit. The trajectories reach distances of up to 38 cm from the axis and the ring slit has a radius of 33 cm. The relation between the resolution and transmission has been measured for feur source diameters. Using a scintillation detector of 1.85 cm diameter and 1 cm length, a resolution W of 1.28% at a transmission T of 1% of 4 pi has been found for a source of 1 cm diameter. For a 1 mm source the measured values range from W = 0.4% at T = 0.8% to W = 1.52% at T = 5.2%. (auth)
