Who are we?

NAPA TECHNOLOGIES is a start-up from NILAB, founded in 2014 by three former managers of the Crystals and Detectors business of Saint Gobain, the world leader in materials for scintillation and nuclear detection. We are based at Archamps Technopole on the French-Swiss border near Geneva.
We share a 2 000 m²  plant with industrial wafer manufacturer Sil’tronix Silicon Technologies.

NAPA TECHNOLOGIES develops innovative surface nanostructuring technologies to improve the performance of scintillators and nuclear detectors based on an original idea from our partner CERN.

The team includes 10 highly skilled staff, mostly qualified engineers and PhDs.

It is supported by the NILAB (Nano Imprint Laboratory), a technology platform that brings together first class academic and industrial partners. Thus, in addition to its internal resources, NAPA can call upon wide scientific and technological resources to assess your requirements and best respond to your specifications.
