UCLH Proton Beam Therapy Centre

An installation of exceptional precision for a new generation cancer treatment facility Get in touch

Project Overview

This is the leading edge of science; a 90 Tonne ‘cyclotron’ cooled to – 269C that spins ionised hydrogen at two-thirds the speed of light and creates a beam of protons which can deliver cancer therapy with millimetre accuracy. 

Making that happen is serious engineering and TClarke have played a major role, working in London’s biggest excavation, in basement areas five storeys and 28.5 metres deep, precision-installing our own prefabricated modules which form part of the Proton Beam installation. 

These modules contain electrical conduits from 160mm down to 35mm, including Stainless Steel Chilled Pipes, 500mm Ventilation ducts, Medical Gas Pipes, 350mm Cyclotron Quench Pipes and Vacuum pipes, Where it wasn’t feasible to install modules TClarke installed over 2800m of loose lay conduits, a combined total  over 8000 metres of plastic conduits and over 400m of Stainless steel pipes. All of these are buried beneath approximately 21,000 cubic metres of concrete.TClarke delivered the full service of precision manufacture and installation of prefab modules.


“We have had total control from design through manufacture to installation. This has allowed us to offer our clients the precision engineering a project like this demands.”

Clive Carr, Director, TClarke London

TClarke's Steve Davies introduces the project

We built modules of exceptional accuracy. We installed them to tolerances of +/- 10mm, working closely with Bouygues. We're proud to be part of this breakthrough facility.
