Abstract

A cross section measurement with a direct 16O detection method for the reaction energy from Ecm= 2.4 down to 0.7 MeV is planned at Kyushu University Tandem Laboratory(KUTL). To perform the experiment successfully and to get the quantitative information of the cross section within the 10% error, we have newly developed several instruments in 2009, such as a blow-in type windowless gas target and movable slit system placed in the recoil mass separator. By using the windowless blow-in gas target, a pressure of 24 Torr was achieved. The effective thickness along the beam axis was measured by p+4He scattering. Thanks to the movable slits installed in a recoil mass separator and the trajectory analysis, we found effective reduction of background conditions from the 12C beam.
