TLDR
In this article, a simple high-current low-emittance dc ECR proton source was developed for a cw RFQ accelerator injector, and the normalized rms emittance of a 25 mA beam from a single 4.0 mm diameter extraction aperture was 0.07 π mm mrad corresponding to a brightness of 5 A/(π mm mdr)2.Abstract:
A simple high-current low-emittance dc ECR proton source has been developed for a cw RFQ accelerator injector. Proton fractions of up to 90% have been obtained at beam current densities as high as 350 mA/cm2. The normalized rms emittance of a 25 mA beam from a single 4.0 mm diameter extraction aperture was 0.07 π mm mrad corresponding to a brightness of 5 A/(π mm mrad)2. Similar results were obtained with multiple aperture extraction systems.read more

An advanced high-current low-emittance dc microwave proton source
Terence Taylor,Jozef F. Mouris +1 more
TL;DR: In this paper, the high-current low-emittance microwave proton source introduced two years ago at the Chalk River Laboratories has been extensively redesigned and the 2.45 GHz microwave line was modified to incorporate a 50 kV dc break and a rectangular-to-ridged waveguide transition.
