TLDR
A broad range magnetic spectrograph for precise measurement of the energies and intensities of charged particles from nuclear reactions is described in this paper, where a uniform magnetic field with a circular boundary focuses particles from a source outside the field along a hyperbolic focal surface.Abstract:
A broad‐range magnetic spectrograph for precise measurement of the energies and intensities of charged particles from nuclear reactions is described. A uniform magnetic field with a circular boundary focuses particles from a source outside the field along a hyperbolic focal surface. Particles with energies varying by as much as a factor of 2.5 may be simultaneously recorded on nuclear‐track plates. Under routine operating conditions, an energy resolution of better than 1000 is obtained over the length of the focal surface. The design, construction, testing, and operation of the spectrograph are described, and plots of dispersion, magnification, aberration, and calibration are given.read more
