Design and testing of the 2 MV heavy ion injector for the Fusion Energy Research Program

The Fusion Energy Research Group at the Lawrence Berkeley Laboratory has constructed and tested a pulsed 2 MV injector that produces a driver size beam of potassium ions. This paper will describe the engineering aspects of this development which were generated in a closely coupled effort with the physics staff. The details of the ion source and beam transport physics are covered in another paper at this conference. This paper will discuss the design details of the pulse generator, the ion source, the extractor, the diode column, and the electrostatic quadrupole column. Included will be the test results and operating experience of the complete injector.
