A large type of mass spectrometer was designed and constructed for the purpose of analyzing impurities in a standard sample of radioactivity. The apparatus is of a single focussing type with 90 deg magnetic sector field, and the radius of ion beam is 80 cm. Some other specifications in designing the spectrometer are as follows: ion accelerating voltage, maximum 30 kv; accelerating voltage of bombarding electron, 60 to 100 v; field of analyzer magnet, 0 to 6,000 gausses; scanning, magnetic; ion-beam detecting system, 100% feed back d-c amplifier and high speed pen recorder; evacuating system, two 3" diffusion pumps with nitrogen cold traps. Several tests on the apparatus were made with three rare gases (neon, xenon, and krypton) and two hydrocarbons (propane and n-butane). The resolving power obtained from these tests was about 600 to 650. A further test with mixture of carbon dioxide and propane gases was made to ascertain the result. (auth)
