D-Beam

D-Beam, a new spin-off company from the University of Liverpool and the Cockcroft Institute in the UK provides a range of reliable and cost-efficient beam diagnostics for use at accelerator and clinical facilities, light sources, and reactors for applications in research, healthcare, security, environment and manufacturing.

Beam diagnostics is a highly specialised area where it takes many years to develop a new sensor technology. The first advantage of D-Beam is the availability of a broad range of cutting edge beam diagnostics solutions that are not currently offered by any other company.

Secondly, we have the required skilled experts to optimise a given diagnostics technology platform towards your specific applications.

Custom-designed radiators

We offer radiators for high current/high energy beam applications, as well as highly sensitive radiators for low intensity beams where a small number of particles need to be detected. Our radiators can be used for single particle detection as well as for beam loss monitoring applications. They are based on the generation of scintillation and Cherenkov radiation in different types of optical fibres and cutting edge photo detectors.

Light transport systems

A major challenge in radiation-intense environments is the signal transfer from the source to the (often expensive and not radiation-hard) detection system. Lens-based light transport systems suffer from aberrations, misalignment and radiation damage. D-Beam offers optical fibre based light transport systems that can replace conventional lens-based systems.

Amongst others, we are experienced in the development, optimisation and experimental exploitation of synchrotron radiation-based profile monitors, novel micro mirror array-based beam halo monitors for the measurements with high dynamic range, and advanced sensor technologies, such as silicon photomultipliers.

Beam Loss Monitors (BLM) based on fibres

D-Beam offers BLMs based on fibres with unique features compared to the commonly used BLMs. The fibre-based BLM gathers the information from the entire beam line you are interested in, and not only one point.

Due to the large number of monitors necessary to cover all beam modules in latest generation large scale accelerators, it is desirable to find a solution which minimises also the overall costs of the system. The use of optical fibres in different configurations allows covering larger segments of the machines. This allows to find new sources or losses and to protect the equipment.

Our systems provide a resolution of around 10 cm, which gives an accurate determination of the loss position. Due to their intrinsic design advantages our systems are completely insensitive to magnetic fields and neutron radiation.

Self-mixing sensor

We offer a compact laser diode based sensor for detecting a small displacement and measuring the vibration with an accuracy of better than 300 nm. This easy-to-use sensor can be easily used for many purposes including cryogenic chamber vibration detection or referencing the displacement of wired or translational stages for diagnostics. Moreover, it can also be used for velocity measurements of gas-jets and fluid targets. Our sensor provides a reliable, low cost and robust solution that can be used in even the harshest environments.

D-Beam offers easy-to-use and user friendly diagnostics for charged particle beams. This includes custom-build diagnostics for your specific needs. We have a wide range of numerical and analytical tools for modelling and optimising our products for even the most challenging projects. We have established a collaborative network with universities, research centres and industry partners from all over the world.
