A new gamma-ray facility at HIGS: The Clover array

ORAL

Abstract

A new gamma-ray facility has recently been commissioned at the HIGS facility at TUNL. The clover array is composed of 8 HPGe detectors of the clover type as well as of 12 CeBr$_3$ scintillators. The facility is expandable to 12 clover systems, and can also accommodate other scintillators as well as other types of detectors as needed. This setup is designed to enable multi-parameter coincidence measurements and will have sub-nanosecond timing capabilities. It will also take full advantage of the increased gamma-ray fluxes which have recently become available at HIGS. Digital electronics is used for signal processing. The facility has been successfully commissioned very recently in a nuclear resonance fluorescence measurement. The performance of the full array will be discussed based on the data from this first experiment.
