The IPM Electron Linac is an 8 MeV (upgradable to 11 MeV) electron linear accelerator under development at the Institute for Research in Fundamental Science (IPM), Tehran, Iran. The linac is ma inly regarded as a research project providing hands-on e xperience in the accelerator science and technology. However, it could serve as an x- ray source or play the injector role for a larger facility. The linac consists of a thermionic gun followed by a travelling wave buncher joine d to two accelerating tubes. The transverse focusing is provided by the solenoid mag- nets over the buncher and the accelerating structures. Using the code ASTRA, the transverse beam dynamics is studied and optimized in order to limit the RF emittance. Particularly, the effect of coupler asymmetry is investi- gated, a beam dynamics design of the solenoid channel is presented, and the effect of the solenoid misalignment on the beam quality is examined.
