ZEUS 2

Name: Zeus2
Author: Nuclear Instruments

ZEUS 2 is the official cross-platform application for configuring, controlling, and monitoring High Voltage (HV) power supplies from CAEN and Nuclear Instruments. Designed for laboratory, research, and industrial environments, it provides an intuitive interface for managing one or multiple devices through USB, Ethernet, USB HID, or I²C connections.

The application simplifies every aspect of HV system operation, from configuring device parameters and monitoring real-time measurements to recording experimental data and performing detector characterization. Live charts allow users to visualize voltage, current, and temperature measurements, while integrated data logging and export capabilities make it easy to collect and analyze results. Advanced features such as temperature compensation, lookup table (LUT) programming, I-V curve acquisition, and device calibration are seamlessly integrated into a modern, user-friendly interface.
