The fabrication of metallic 7Be targets with a small diameter for 7Be(p,γ) 8B measurements

The fabrication process for a metallic 7Be target of small diameter is described. Targets fabricated in this manner have been subjected to systematic tests and one of them has been used in a 7Be(p,γ) 8B measurement at the University of Washington.

Description
Summary:The fabrication process for a metallic 7Be target of small diameter is described. Targets fabricated in this manner have been subjected to systematic tests and one of them has been used in a 7Be(p,γ) 8B measurement at the University of Washington. Target properties have been determined including the total amount of 7Be, the 7Be distribution over the target area derived via a decay γ-scan and the 7Be depth profile. The latter has been measured with the E α =1376 keV resonance in the 7Be ( α, γ) 11 C reaction.
