- "In further reference to [Bainbridge's letter,  I should like to lodge an objection to his application of the word 'mass-spectrograph' to Dempster's form of analysis. This word I coined in 1920 to describe an instrument which by its peculiar sequence of and magnetic fields eliminated the effect of varying velocity and gave a spectrum dependent upon mass alone. Dempster's apparatus, described two earlier, is essentially an application to the analysis of positive rays of the well-known and widely used principle of semicircular magnetic focusing. an instrument gives a magnetic spectrum which depends upon momentum and not upon mass The fact that it is the standard method for determining the energies of beta particles makes this sufficiently obvious. The use of the word mass-spectrograph, unqualified in any way, to an apparatus not using in any manner the principle implied in it, appears to me to be a misleading and undesirable practice."
