Matching from H− multicusp source to central region of a 100MeV compact cyclotron for high current injection

Abstract

The way of matching the beam from an external ion source to the central region of the cyclotron CYCIAE-100 is presented in this article. The transverse acceptances of the central region were calculated, which provided the matching ellipse parameter requirements to the injection transport optics design. The optics of the injection line was simulated using TRANSOPTR, which allowed space charge effect calculation, and neutralization was taken into account.

“…The extracted beam intensity for CYCIAE-100 is required to reach 200 µA, and it is planned to a provide a pulsed beam as well. In order to get a high average beam intensity and to be capable of providing the pulsed beam, two beam lines for the axial injection are considered, corresponding to Line 1# and Line 2# respectively [7]. Line 1# takes advantage of the neutralization of the H − beam.…”
