A segmented, enriched N-type germanium detector for neutrinoless double beta-decay experiments
Abstract
We present data characterizing the performance of the first segmented, N-type Ge detector,
isotopically enriched to 85% 76Ge. This detector, based on the Ortec PT6×2 design
and referred to as SEGA (Segmented, Enriched Germanium Assembly), was developed as
a possible prototype for neutrinoless double beta-decay measurements by the Majorana
collaboration. We present some of the general characteristics (including bias potential,
efficiency, leakage current, and integral cross-talk) for this detector in its temporary
cryostat. We also present an analysis of the resolution of the detector, and demonstrate
that for all but two segments there is at least one channel that reaches the Majorana
resolution goal below 4 keV FWHM at 2039 keV, and all channels are below 4.5 keV FWHM.

Professor Emeritus of Physics
Professor Werner Tornow became the Director of TUNL in July, 1996. He is primarily
interested in studying few-nucleon systems with special emphasis on two-nucleon systems
and three-nucleon force effects in three-nucleon systems. Polarized beams and polarized
targets are essential in this work. He collaborates with the leading theoreticians
in his field to interpret the experimental data obtained at TUNL. He recently became
involved in weak-interaction physics, especially in double-beta decay s
