RESEARCH ON COLLISION PROCESSES OF ELECTRONS AND ATOMS.
Abstract
A summary is given of the method being used to measure the cross section for ionization of nitrogen and oxygen atoms by electrons. The reaction e(-) + N to N(+) + 2e(-) has been observed, however, actual measurements were postponed pending further refinement of the apparatus. The development of the apparatus during the past year is described, including an improved low-noise, highly sensitive current-measuring system. A sensitive instrument for monitoring neutral beam currents of known energy by measuring the associated thermal power is described and analyzed. The instrument has a sensitivity of 50 microvolts per milliwatt. Several gases have been tested for their ability to produce neutral beams from N2(+) and N(+) beams via the chargetransfer process. Results of these tests are presented. (Author)
