dc.description.abstract A thin-lens beta-ray spectrometer using ring-focus collection was modified. These modifications consisted of; 1) a centering mechanism enabling the source-detector axis to be aligned with the magnetic axis; 2) an extension of the vacuum chamber placing the detector further from the magnet coils. The latter considerably decreased the magnetic shielding requirements for the detector. A misalignment of 0.25 mm. for parallel axes and of 0°09' for intersecting axes produced noticeably poorer performance. Using a gathering power of .70%, a resolving power of .94% was obtained for the 661.6 Kev. K-conversion peak of Cs ¹³⁷. en
