An experiment to inject and match a 10  μs, singly charged K+ ion bunch at an ion energy of 0.3 MeV, current of 45 mA, and dimensionless perveance of 10-3 into a solenoid lattice has been carried out at LBNL. The principal objective of this experiment is to match and transport the space-charge dominated ion beam and compare predicted and measured emittance. Initial investigation also presented the opportunity to study electron cloud effects and the effects of misalignments. A qualitative comparison of experimental and calculated results are presented, which include time resolved current density, transverse distributions, and phase space of the beam at different diagnostic planes.
