A High-Intensity Source of $^6$He Atoms for Fundamental Research

ORAL

Abstract

We have designed and built a lithium target station for the production of $^6$He atoms for fundamental research. The system relies on the reaction $^7$Li($^2$H,$^3$He)$^6$He using a deuteron beam provided by the tandem Van de Graaff accelerator available at the Center for Experimental Nuclear Physics and Astrophysics of the University of Washington reaching a maximum intensity and energy of 10$\mu$A and 18 MeV. The extracted intensity of gaseous $^6$He atoms was measured to be $\sim$10$^9$ atoms/s in a low-background experimental area. This represents the highest intensity of $^6$He currently available in the world. This presentation will discuss the details of the target design and give a brief overview of the experimental program.
