Design studies of Superconducting Super Collider (SSC) low-energy- beam-transport system using einzel lenses.

摘要

A 35 keV preinjector for matching a 30 mA H(sup (minus))beam into the radio-frequency quadrupole (RFQ) section of the SSC linac has been designed using the SNOW code. The distinguishing feature of this injector is that the conventional gas-neutralized transport and matching units are replaced by two einzel lenses. Some advantages of this approach are discussed. 7 refs., 5 figs., 3 tabs.
