Summary of the contracting process

NPL Management Limited procured a specialist high-purity germanium (HPGe) gamma-ray detector and cryogenic cooling system for high-resolution gamma-ray spectroscopy, ionising radiation measurement, nuclear metrology and scientific research at the National Physical Laboratory’s Centre for Ionising Radiation and Metrology in Teddington. The supply includes an ORTEC GAMMA-X coaxial N-type HPGe detector with carbon-fibre window, remote preamplifier and high-voltage filter; a J-type streamline cryostat; a Möbius Recycler cooling system; configuration packages for the detector and cryostat; and accessories. This is specialist scientific measurement equipment for radiation metrology and research, rather than general laboratory instrumentation.

The procurement is complete and the contract is active. NPL Management Limited awarded the single lot to AMETEK (GB) Limited following a below-threshold direct award without competition. The award date and contract signature date were 4 September 2026. The contract runs from 4 September to 31 December 2026. Its value is £6,591,000 excluding VAT (£7,909,200 including VAT). The published information does not set out an evaluation basis or supplier eligibility criteria. The contract covers supply and delivery of the detector, cryogenic cooling equipment, configuration packages and associated accessories.

This award shows demand at NPL for high-specification HPGe detector systems and compatible cryogenic cooling equipment supporting gamma spectroscopy, ionising-radiation measurement and nuclear metrology. A credible competitor would need to supply an integrated, specialist system, including detector, cryostat and cooling components, configuration and accessories, with the technical capability to support precision scientific measurement and research. Experience delivering comparable instrumentation and ensuring that detector and cooling equipment work together would be directly relevant. The buyer used a direct award without competition for this below-threshold purchase, and selected AMETEK (GB) Limited. Suppliers should therefore recognise both the specialist nature of the requirement and the route used for this procurement when assessing the commercial relevance of similar work at NPL.
