Abstract

A new measurement of the cross section of ⁷Be(p,)⁸B will be done in inverted kinematics with the recoil separator ERNA at the CIRCE laboratory in Caserta, Italy. The ⁸B recoils will be produced in a windowless hydrogen gas target. We report here on the construction and characterization of the gas cell. In detail we describe measurements for target density, the profile determination via the ⁷Li(p, p’)⁷Li^* reaction as well as the role and performance of a gaseous post-stripper.
