A laser-induced neutralization technique, LINDA, has been used to study the longitudinal emittance of the 5-MeV H{sup {minus}} beam exiting the drift-tube Linac (DTL) of the Los Alamos Accelerator Test Stand (ATS). By using multiple laser intersection points, longitudinal emittance growths over drift distances of 23.6 and 30.6 cm were measured. Subsequently, a beam transport line, which consisted of one arm of a beam funnel, was substituted for the drift space. Measurements show that the elements of the funnel constrain emittance growth while the H{sup {minus}} beam is contained within these transport elements.
