Commissioning of a new decay-detection array/tape transport station for CARIBU

ORAL

Abstract

The CARIBU facility [1] at Argonne National Laboratory provides a unique opportunity for research in nuclear structure, nuclear astrophysics and applied applications. A new decay-detection array for performing $\beta $-$\gamma $ coincidence measurements is being commissioned for use with exotic stopped beams. The new array consists of the existing ``X-array,'' with five HPGe detectors for detection of $\gamma $ rays, and a plastic scintillator for $\beta $-particle detection. Two operational modes are possible: ``Mode 1'' utilizes a stand-alone scintillator chamber; ``Mode 2'' incorporates a tape transport system into a modified chamber, offering significant contamination removal that would otherwise result from the subsequent decay chain. The design of the tape station has been adopted from a prototype diagnostic system currently installed at CARIBU. Here, a general overview of the apparatus, commissioning runs and analysis of data collected whilst operating in both modes will be discussed. \\[4pt] [1] G.
