摘要：

We describe the construction and performance of an apparatus to measure the polarization of protons in the kinetic energy range 100∼400 MeV, operated with an extracted electron beam and a high-intensity bremsstrahlung photon beam. It consists of four multiwire proportional chambers, a spectrometer magnet, ten wire spark chambers with magnetostrictive readout, a carbon scatterer of variable thickness and a range counter hodoscope. The multiwire proportional chambers are placed before the magnet and are directly exposed to intense electromagnetic background coming from a target. For this reason, special care is taken of the readout electronics. A method of polarization analysis is also described in detail. © 1979.
