Emittance measurements of low-energy beam line at KVI

In this paper is represented the results of beam profile measurements of 3He+ beam delivered from ECR ion source at KVI. The beam emittance is estimated by varying quadrupole method. The estimated values for the beam emittance at the different profile grid locations along the transport beam line shows that beam emittance in the both, horizontal and vertical planes is not conserved. That means there is a strong-coupling effect and/or the beam is losing through the transport line.
