Abstract

Gamma-ray detector systems are important in many areas of science, and the significant advances in such systems open possibilities to address new and interesting questions. A high-resolution γ-ray detector system with completely new capabilities is possible today, and a proposal for its construction is under consideration by the DOE. The new capabilities have to do with the resolving power of γ-ray detectors; that is, their ability to isolate one sequence of grays from a complex spectrum. Higher resolving powers can be achieved by using the additional information contained in the higher-fold coincidence events, and about three orders of magnitude improvement over existing detector systems is anticipated. Much of the frontier work involving γ-ray detection requires the study of weak signals embedded in very large backgrounds, and this enormous gain in resolving power will have a large impact on these studies. The system proposed consists of 110 large compton-suppressed Ge detectors and has about six times higher efficiency for a ≈1 MeV γ-ray than any existing detector system. The primary use envisioned for such a detector system would be in studies of the structure of nuclei; however, it will have an impact in many other fields, including atomic physics, electro-weak physics, astrophysics, and some “new and undefined” physics.
