Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive calibration of the geometry of the NBS electron scattering apparatus is described. A complete set of measured parameters is tabulated in this report. Combining these parameters with observed values of certain variables as described herein permits the accurate determination of the solid angle, scattering angle, and target angle for each cross section measurement made with the apparatus. The uncertainty in a cross section measurement due to the imprecision of the geometry calibrations is less than one part in 103.

Book excerpt: Excerpt from Geometrical Calibration of the Nbs Electron Scattering Apparatus The nbs electron scattering apparatus is shown in figure I. The detector system and shielding platform which are mounted to the upper half of the spectrometer magnet are omitted from this figure for clarity. The energy-resolved electron beam is incident from the right in figure 1, in a u - inch diameter vacuum pipe. The beam is approximately one - half inch in diameter when it enters the magnetic field of the quadrupoles. The beam is focused by the quadrupoles to a spot of less than 1 mm diameter at the target. After leaving the quadrupoles, the beam passes through the upstream beam profile scanners, whose function is to measure the size and position of the beam at this point. The beam then passes through a non-intercepting current monitor which is part of the charge measuring system The beam pipe diameter is reduced to two inches between the current monitor and the scattering chamber. In order to be able to determine the beam direction at the target, the region between the upstream beam scanners and the target is kept free of magnetic fields by wrapping the pipe with magnetic shielding. The scattering chamber is an 18 - inch diameter vertical aluminum cylinder. Ports on the scattering chamber at intervals between MO and allow direct connection of the beam-line and the spectrometer vacuum systems.
