| Abstract We report on a new liquid hydrogen target dedicated to in-beam gamma spectroscopy experiments in inverse kinematics at relativistic incident en- ergies at GSI/FAIR. The target-cell and entrance window are composed of 200-m thick Mylar. Target thicknesses from 10 to 60-mm can be reached for an e ective diameter of 70 mm. The proposed design has the advantage of being free of absorbing material at forward angles and 90 degrees, allowing the detection of photons on a wide angular range. A commissioning experi- ment with a 54Cr beam at 130 MeV/nucleon has been performed at GSI with the RISING setup. The target has been shown to behave as expected and is ready for experimental campaigns with AGATA. |
