Vertical Charge Exchange Cell for Collinear Laser Spectroscopy at NSCL
ORAL
Abstract
A vertical charge exchange cell (CEC), originally developed at TRIUMF/ISAC, has been constructed at NSCL for the Beam Cooling and Laser Spectroscopy (BECOLA) system. The CEC was initially commissioned at the TRIGA-Laser facility at the University of Mainz by neutralizing a 10 keV Rb$^{+}$ ion beam with K vapor. The neutralization efficiency was measured as a function of the CEC heater temperature. The line shape of the Rb D2 transition was also examined in relation to the neutral fraction of the Rb beam. Details of the CEC design and operation, as well as the results of the tests will be discussed.
