Effective low-background environment for spectroscopy

Abstract

A new detector array, Solenogam, has been developed at the Australian National University Heavy Ion Accelerator Facility. Coupled initially to the SOLITAIRE 6.5 T, gas-filled, solenoidal separator, and later to an 8 T solenoid, the system enables the study of long-lived nuclear states through $\gamma$-ray and conversion-electron spectroscopy in a low-background environment. The detector system is described and results from the commissioning experiments are presented.
