Designing a beam transport system for the EG and G/EM electron linac with the matrix multiplication computer code, TRANSPORT, leaves unresolved questions as to the effects of space charge and emittance growth on beam radius, as the code assumes constant emittance and no space charge. ZFIELD, a trajectory computer code for a linac beam, has been written as a design aid. It includes space charge, plots the emittance ellipse at axial values, and plots beam radius. Comparing ZFIELD and TRANSPORT in drift regions, significant differences in beam radius predictions are found in the 2-MeV region for currents above 200 A and above 400 A in the 4-MeV region. Beam envelope growth for beams with different emittance is compared using ZFIELD. The effect of space charge on emittance growth is shown graphically. 6 references, 4 figures, 1 table.
