Proceedings of the Indian Academy of Sciences - Section A Aims and scope Submit manuscript

Summary

An electrostatic beta-ray spectrometer using a spherical condenser has been constructed for study of weak sources, and its performance has been tested with accelerated electron beams. The device, which is intended for low energy range of electrons, has, for the slit system employed, the resolving power of 1·6% with transmission 1/44 of a sphere which compares favourably with that in other types of spectrometer. The electron energy E (in KeV) focussed is 4·37 times the voltage V. in K.V. on the electrodes.
