Founded in Viareggio, Italy by a team of senior engineers from the Istituto Nazionale di Fisica Nucleare – INFN, we built our foundation on deep expertise in nuclear and particle physics instrumentation, driving innovation and excellence in electronic systems for scientific research.

We introduced our first high-voltage power supply system, setting a new standard in design. Over 30 years, we delivered 400,000 HV channels worldwide, establishing ourselves as a leader in high-precision power solutions for scientific research.

In 1991, we pioneered VME design for the nuclear market, specializing in Front-End (FE) and Data Acquisition (DAQ) systems. Over 25 years, we delivered 600,000 channels worldwide, reinforcing our role as a trusted provider of advanced nuclear instrumentation solutions.

Since 1998, our UNI EN ISO 9001 certification highlights our dedication to quality management. Upgraded in 2001 to UNI EN ISO 9001: Vision 2000, we consistently deliver reliable, high-quality solutions, focusing on customer satisfaction and continuous improvement to meet global standards.
