DESIGN OF A MAGNETIC SPECTROMETER FOR PHOTOELECTRON SPECTROSCOPY

We present the results of a computer design study for an iron-free double-focusing magnetic spectrometer specifically intended for photoelectron spectroscopy. With single detector operation the proposed design is more efficient than any existing magnetic double-focusing spectrometer, and the focal-plane characteristics allow more than a 100-fold increase in data accumulation rate with a multichannel detector. This design also has very high physical accessibility near the source and detector areas and it is compatible with either normal or ultrahigh vacuum operation. © 1969 The American Institute of Physics.
