[Tony Messina] had been fascinated with bat’s echolocation since he was a kid. After he retired, he decided to act on this fascination and built a simple bat detector.The simple bat detector … ...

Experiments are described in which the performance of a linear type detector circuit is compared with a mean square type detector circuit for Campbell measurements. The need for pulse overlap is ...

This article presents the development of a cryogenic bandgap reference (BGR) circuit in a standard 0.18-μm CMOS process for high-purity germanium (HPGe) detectors for low-background physics ...
