ZEUS 2

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.

Key Features

• Control one or multiple HV power supplies from a single application
• Monitor voltage, current, temperature, and device status in real time
• Configure operating parameters, protection limits, and ramp rates
• Acquire and visualize I-V characterization curves
• Program temperature compensation lookup tables (LUT)
• Access device-specific advanced configuration and calibration settings
• Record measurement data in CSV or JSON formats for offline analysis
• Group devices and channels for simplified operation
• Support for USB, Ethernet, USB HID, and I²C communication interfaces

Installation

Windows

Download the latest Windows installer from the versions section and run the setup.

The installer includes the ZEUS 2 application together with all required runtime libraries.

Linux

ZEUS 2 is distributed through the official Nuclear Instruments Package Repository.

Configure the repository by running:

curl -fsSL https://sh.nuclearinstruments.eu/ni-repo | bash

Once the repository has been configured, install the package using your distribution's package manager.

Ubuntu / Debian

sudo apt install zeus2

AlmaLinux

sudo dnf install zeus2

The package manager automatically installs all required runtime dependencies.

Supported Devices

ZEUS 2 supports a growing range of CAEN and Nuclear Instruments high-voltage power supplies connected through USB, Ethernet, USB HID, or I²C.

Refer to the product documentation for the complete list of supported devices and communication interfaces.
