COLD CATHODE GASEOUS DISCHARGE DEVICE FOR PRODUCING ELECTRONS IN AN X-RAY FLUORESCENCE ANALYSIS APPARATUS

摘要

Examination of the composition of a preparation by means of X-ray fluorescence is difficult in the case of elements of lighter weights. An improvement is achieved by causing the preparation to produce X-rays from the lighter-weight elements by the bombardment of slow electrons, produced in a gas discharge, the cold cathode and the preparation space forming an equipotential space. Gas released from the preparation then has little influence.
