摘要：

A new dynamically polarized proton target at LANL polarizes an epithermal neutron beam in the energy range from 0.1 eV to 50 keV. In a He-4 bath at a temperature of 1.1 K, irradiation doped ammonia is polarized longitudinally in a magnetic field of 5 T. The sample has a diameter of 80 mm and is 13 mm thick. The typical proton polarization is 0.85 giving a neutron polarization of 0.75. With the polarized neutron beam parity violation has been studied in many samples with a high degree of sensitivity.
