The duty cycle is given in reference [4] as N r;::;' where N is the number of stages and R is the R8-y3 resolution. An instrument of this type having 20 stages thus has a duty cycle less than 3 percent at a resolving power of 50. 2. Theory of Operation The mass spectrometer reported here resembles the
