Detector Signals

Gammasphere detectors give data back through specific signals. The main signals are called GeCenter, GeSides, BGOSum, and now, after upgrades, BGOPatterns. These signals are defined by the way gamma-rays hit different parts of the HPGe inside a detector. The different points where the HPGe can be hit are called "contact points".

GeCenter

The germanium inside each detector is a cylindrical shape with a hole through its center. It becomes a contact point known as the "GeCenter".
