A new measurement of the cross section of Be-7(p, gamma)B-8 will be done in inverted kinematics with the recoil separator ERNA at the CIRCE laboratory in Caserta, Italy. The B-8 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 Li-7(p, p%26apos;)Li-7* reaction as well as the role and performance of a gaseous post-stripper.
