We present a progress report on the development of a positron spectrometer^1 designed to examine only the low-energy tail of the spectrum of positrons from beta decay. The production of low-energy positrons is important for a variety of applications, including surface studies, symmetry studies of trapped positrons, and attempts to produce anti-hydrogen. Our spectrometer uses a nearly solenoidal magnetic field to transport only the low-transverse-momentum positrons to a counting region where annihilation gamma rays are counted using coincidence techniques. Longitudinal electric fields are used to analyze the longitudinal component of momentum. Data from a degraded ^22Na source will be described to illustrate some features of the spectrum typical of beta sources of positrons, the implications of this spectrum for the operation of the device and enhancing the suitability of the positron spectrum for low-energy applications. ^1Mark Schneider et. al.
