Tunable diamonds that open up new realms of performance
Euclid has led the way in lab-grown high-crystallinity high-purity, single crystal HPHT/CVD diamonds with doping capability and customized features that achieve performance breakthroughs for research and industry.
Diamonds and diamond-based applications
In addition to lab-grown diamonds, Euclid develops diamond-based optical and electronics applications for high energy and nuclear physics, defense, space exploration, medicine, and quantum information /sensing. (Shown: HPHT reactor in Euclid laboratory)
Diamonds are a scientist’s best friend
The diamond has a track record of unique physical properties, well beyond commonly known ultra-hardness and inextricable connection to love and romance, such as:
- The highest thermal conductivity of any material at room temperature
- Very high breakdown electric field threshold
- Radiation hardness
- Transparency to ultraviolet light
- Biochemical inertness


HPHT reactor at Euclid
Made in America to power the next generation
Euclid has established the first U.S.-based capability to grow next generation HPHT and MPE CVD diamonds for the high energy physics community. We have customized our reactors to craft our made-to-order solutions, which include:
- 3D Diamond detectors and Beam Monitor sensors for High Energy Physics applications
- Diamond detectors for Dark Matter search
- Radiation tolerant high-power high-temperature diamond transistors for defense and space
- A new line of diamond-based cathodes
- A single-crystal diamond compound refractive lens (CRL)
and X ray Phase plates to focus X-rays for next
generation light sources. - CVD diamond-based Wakefield accelerator structures for
THz frequency ranges - Diamond capillary technology for laser-plasma wakefield

Plug-&-play solutions for advanced physics research
Euclid’s ongoing contributions to advanced physics research includes our work with Argonne National Lab. Our plug-and-play solution for a superior electron emission source, based on ultra-nanocrystalline diamond (UNCD), overcomes the complexity and cost disadvantages of typical cathodes. Our field emission cathode (FEC) performs better even in planar configurations, and has survived under harsh conditions in RF guns without degradation, while delivering a brighter beam.

Euclid has customized our CVD reactor to
produce the highest quality diamonds
The only diamonds that meet Euclid’s own standards
Euclid products ranging from accelerator components to our new compact portable accelerator incorporate diamonds we have custom-developed for our own use. The first CVD diamond in a dielectric accelerating structure was developed by Euclid, delivering a record high accelerating gradient in THz frequency range. Our Ultra-Nano Crystalline Diamond Field Emission (UNCD-FE) cathode for high current applications (10 mA per pulse) is at the heart of our compact portable accelerator.
