IONIZATION YIELD OF LOW-ENERGY HEAVY IONS IN ARGON

Technical Report ·
OSTI ID:4085063
Presented at the New York Meeting of the American Physical Society, January 27, 1960. A cylindrical ionization chamber with a differentially pumped open window was used to measure the total ionization yield of low energy heavy ions stopped in a gas. The ionization yield of protons in argon at 25 to 250 kev was determined earlier. Recent results are presented on the ionization yield of argon and nitrogen ions in argon gas at 25 to 100 kev. The average energy per ion pair for argon ions increase rapidly with decreasing energy in the above range, and at 50 kev it is about three times the value for 200 kev protons. A comparison of the ionization yields in argon of various ions having velocities in the same region is presented. (auth)
