Abstract : This report covers the period June 1981 to June 1983, during which time investigations were conducted into several major topics concerning the behavior of an intense (multi-kiloampere) electron beam in the modified betatron electron accelerator. The modified betatron has been selected for experimental evaluation as a high-current electron accelerator. Theoretical support has been directed at identifying those phenomena which will most directly affect accelerator performance. To this end, research has been carried out in the following areas: (1) Transverse linear beam dynamics in time varying, azimuthally symmetric fields, (2) Effects of grad B theta induced drifts, (3) Orbital resonance effects due to small field errors, (4) Nonlinear effects, especially those due to non constant betatron field index, (5) Collective effects, especially the negative mass instability, and (6) Strongly focused systems.
