MultiX

MultiX S.A. was established on October 15, 2010, as a developer of advanced spectrometric X-ray detectors for material discrimination applications. The company was founded by Jacques Doremus and Patrick Radisson, both of whom previously worked at the Thales group, with support from the French Atomic Energy Commission (CEA). Doremus brought his experience from Thales's Electro-Device subsidiary to lead the new venture. The core of MultiX's business was its proprietary technology, originating from research at CEA Leti and Thales, which enhances the capabilities of X-ray scanners.

The firm concentrated on the security and non-destructive testing markets, providing solutions for identifying materials and detecting explosives in luggage and packages. Its technology distinguished itself by being able to precisely identify various substances based on the unique number of photons that pass through them, a significant improvement over traditional X-ray systems that only differentiate between organic, metallic, and inorganic materials. This capability aimed to reduce false alarm rates, thereby lowering operational costs for clients like airport operators. The business model involved supplying complete X-ray detector systems, such as the ME100, which were based on Cadmium Telluride (CdTe) and Cadmium Zinc Telluride (CdZnTe) crystal materials, as upgrades to existing X-ray equipment.

In December 2018, Detection Technology Plc acquired the business of MultiX S.A., which was undergoing reorganization proceedings at the time. The acquisition included MultiX's licensing agreements, patents, and other assets, with the 17-person staff also joining Detection Technology. This strategic move expanded Detection Technology's technology base, particularly in direct conversion technology and photon-counting algorithms, strengthening its position in the security, industrial, and medical X-ray imaging markets. Following the acquisition, the MultiX business line and its products were rebranded under the Detection Technology name, with former MultiX products like the ME100 series becoming part of the DT-branded multi-energy product line.
