The proof-of-concept experiment for the Spiral Line Induction Accelerator

A proof-of-concept experiment (POCE) for the Spiral Line Induction Accelerator (SLIA) is underway at Pulse Sciences, Inc. to demonstrate a new compact high current (≳ few kiloamperes) recirculating induction accelerator for high power (≳ 100 kW) commercial processing and other applications. Hardware has been fabricated to generate 9.5 MeV electron beams at 2 and 10 kA by recirculating the beam for two passes through each of two 1.5 MeV accelerating units. Initial experiments have demonstrated acceleration of 2 and 10 kA beams to 5.5 MeV by transport around a complete turn with two passes through a single accelerating unit and work is currently in progress to complete the full POCE. Experimental results to date are reported.
