TMD announces a ‘world’s first’ in portable cold atom technology

TMD Technologies Limited (TMD), world leading West London based manufacturer of equipment for the high-tech microwave and quantum technologies industries, has announced the gMOT, the world’s first portable grating magneto-optical trap for compact cold atom systems.

Magneto-optical trap
The world’s first portable grating magneto-optical trap for compact atomic clocks, inertial sensors, magnetometers, RF field sensing and gravimeters.

In partnership with…

Manufactured by TMD’s Quantum Team in close working association with its academic and scientific partners the University of Strathclyde, University of Glasgow and Kelvin Nanotechnology Limited, the gMOT was built and tested at TMD’s manufacturing and design facility in Hayes, West London.

Emphasising the importance of this quantum breakthrough, the gMOT was displayed by Strathclyde University on its stand at the recent Photonex Europe exhibition in Coventry, and will be on show on TMD’s stand at the prestigious National Quantum Technologies Showcase in London in November.

Said Richard Patrick, TMD’s Head of Business Development: “We started working with Strathclyde University some three years ago, on an accelerator account to design compact vacuum cells. This scientific aspect has now become increasingly relevant to compact cold atomic sensor and clock development, and as a result of its work in this important field TMD is now an active member of the National Quantum Technologies Programme.” (see below).

Continued Dr Edward Boughton, TMD’s Engineering Manager, Applied Science: “The gMOT project has been an exciting challenge for us. We are delighted at the successful outcome and applaud the work of our scientific partners. From TMD’s point of view the key to this achievement has been the multi-disciplinary strengths that it possesses – including familiarity with uncommon elements, extensive experience of ultra-high vacuum design, and unbeatable skill at precision assembly of dissimilar materials.”

Summing up, Richard Patrick said: “Atomic clocks, in particular, are an important facet of our everyday lives in this fast-expanding quantum world. Atomic clocks developed in the Quantum 2.0 programme have the potential to provide a valuable alternative and back-up to GNSS (Global Navigation Satellite Systems) – used as either stand-alone timing solutions on a platform or as ‘hold-over’ clocks should the GNSS signal become unavailable, unreliable or degraded.”
