Power Supply

The Power Supply Systems are the heart of any experiment. They provide the High voltage and Low voltage required by the detectors and by the related front-end electronics. The quality of the power supply is critical to obtain the best performance from the set-up. The sensibility of modern detectors, in fact, make them susceptible to any even small variation in the power supply, and so features like low Noise, low Ripple and high stability become essential in the design of a performing power supply system. Strong of 30 years of collaboration with the most important research labs worldwide CAEN offers today sophisticated High Voltage Power Supply and Low Voltage Power Supply Systems. The demonstration of this successful long-standing tradition is the "CMS Crystal Award 2009" that CAEN received for the development and production of the power system for the CMS tracker. CAEN offers a wide selection of Power Supplies in different form factors and standards:
  • For smaller set-ups Standalone or modular (NIM / VME) products or are the ideal fit.
  • For bigger set-ups, where a high number of High voltages and Low voltages is required, the Mainframe Systems and Boards (up to 48 channels/board) are the most recommended.

Universal Multichannel System

The system has been specifically designed to power all detector technologies found in modern Physics Experiments, such as e.g. photomultipliers, wire chambers, streamers tubes, silicon detectors. The systems are modular, flexible and match not only the requirements of major experiments with large number of channels but also the practical needs of test laboratories, where simple manual operations on a limited number of channels are often desired.


SY4527 - SY5527

The system is organized into Mainframes housing Multichannel Boards (from 4 to 16 / up to 768 channels per mainframe)
