Abstract
The Proof-of-Concept (POCE) experiment for the Spiral Line Induction Accelerator (SLIA) involves injecting a 3.5 MeV, 10 kA electron beam into a strong focussing, two-turn, racetrack type spiral magnetic transport line with two passes through each of two 1.5 MV induction accelerating units, giving a nominal 9.5 MeV, 10 kA, 35 nsec output. The design selected for the 80 cm bends of the POCE is a stellarator achromat which gives an identity transfer matrix to first order in the relative momentum mismatch. Experiments at 1 MeV in a straight stellarator field, which simulated the first POCE bend, demonstrated the existence of the stellarator achromat at the predicted magnetic field values. No charge loss was observed for simulated momentum mismatches of up to +25%. The progress of experiments on matching the 3.5 MeV, 10 kA beam from the field-free diode into the nominal 5 kG axial guide field and the transport efficiency through the POCE bends are reported. The status of the remaining hardware fabrication and the schedule for full scale experiments are summarized.
