摘要: Abstract A 50 cm radius iron-core double focussing beta-ray spectrometer has been equipped with a gamma-ray coincidence arrangement, which can provide measurements of electron-gamma coincidences and angular correlations at high resolution in the electron channel. special detector system, employing between positons subsequent annihilation quanta, constructed. The natural background this system is about 1 count/hour, permits studies extremely low intensity positon distributions. isoaberration curves have measured from these results optimized shapes baffles were magnetic field “magnetic stripping” described as also automized demagnetization unit.
