An attempt was made to measure the asymmetry in pion-proton bremsstrahlung with positive pions at 261 MeV kinetic energy. The experiment was carried out at the TRIUMF cyclotron laboratory. A beam of [pi][sup +] mesons was scattered off a polarized proton target (the TRIUMF frozen spin target) which produced an average polarization of 80% normal to the scattering plane. All three outgoing particles from the bremsstrahlung reaction [pi][sup +]p [yields] [pi][sup +]p[gamma] were detected. The pion momentum was measured with a spectrometer consisting of a dipole magnet and a total of four horizontal drift chambers. The proton energy and angle were measured with an array of plastic scintillator blocks while the photon was detected with one of two large NaI crystals. Data were taken for a total of six weeks in January and April of 1989 at various experimental configurations. Only the most promising part of the data, taken during the last week in April, has been analyzed. Due to technical difficulties, particularly with the detector calibrations, no results for the asymmetry in pion-proton bremsstrahlung could be extracted from the measurements. The author therefore presents the details of the experiment from a general point of view with a special emphasis on the design phases for a new experiment.
