Description
We have designed and installed a high-resolution isobar
separator to be used with a 50-keV ion beam from the CARIBU facility.
It uses two 60º bending magnets, two quadrupole doublets, and two quadrupole singlets in a symmetric combination, and has a design first-order mass resolution of 22,400.
Aberration correction up to 5th order is accomplished by means of two hexapole singlets and a 48-rod electrostatic multipole lens with hexapole, octupole, decapole, and dodecapole components.
Ion-optics calculations were performed using the program COSY INFINITY.
The resulting ion trajectories and mass spectra will be presented, along with a progress report on commissioning.
