The apparatus described may be used to demonstrate the continuous beta spectrum and the electron conversion lines. It consists of a small electromagnet with 4-in.-diam. pole faces, a vacuum chamber of 3.0-cm curvature radius, and a halogen-quenched Geiger tube with a thin mica window (probably 2.5 mg/cm/sup 2/) and a threshold of 500 volts. A 20 microcurie radioactive source was evaporated on a thin Mylar base in this instance. For demonstration purposes current may be measured with sufficient precision with a 1.5 amp full scale meter.
