The ICEBall: a multiple element array for in-beam internal conversion electron spectroscopy

New Instruments And Devices At The Wright Nuclear Structure Laboratory

“…ICEY Ball: The Internal Conversion Electron array at Yale. ICE Ball, which consists of six mini-orange electron spectrometers, is a Gammasphere auxiliary detector, designed and built by Juerg Saladin at the University of Pittsburgh [3]. Following Juerg's retirement WNSL has become the host institution for ICE Ball.…”

“…The YRAST Ball multi-germanium detector array [3] can be mounted at the target position of SASSYER. In this location, YRAST Ball is currently configured with 5 clover detectors at 90 o and four at 41 o with respect to the beam axis, giving a total photopeak efficiency of ε ph ~ 2.7% A maximum of 13 clover Ge detectors can be accommodated.…”

In-beam internal conversion electron spectroscopy with the SPICE detector

“…Subsequently, electron-spectrometers are essential in the study of these transitions. In view of the physics opportunities offered by electron spectroscopy, a number of devices with various designs have been constructed at facilities around the world [9][10][11][12][13][14][15][16][17][18][19][20]. The SPectrometer for Internal Conversion Electrons (SPICE) has been constructed and commissioned for use in conjunction with the TIGRESS spectrometer to perform combined in-beam γ-ray and ICE spectroscopy at TRIUMF's ISAC-II facility with stable and radioactive ion beams.…”

Combined in-beam gamma-ray and conversion electron spectroscopy with radioactive ion beams

“…The structure of the atomic nucleus is a unique and complex quantum mechanical many-body system that has been studied extensively using gamma-ray detector arrays [1,2] and electron spectrometers [3,4] for decades. However, probing nuclear structure by gamma-ray or electron spectroscopy alone can provide only a limited view of the nuclear de-excitation processes.…”
