Description

ASTeC at STFC Daresbury Laboratory hosted a workshop in December 2022 to discuss the sustainability of particle accelerators. The aim was to bring together accelerator scientists, engineers, and other stakeholders to share ideas and best practises to make current and future particle accelerators more sustainable, and to meet the challenges of the 21st century. We want to foster discussion and collaboration between STFC departments, UK accelerator institutes, and overseas partners to establish a common set of technology goals, tools and approaches.

The workshop took place in the Merrison Lecture Theatre at Daresbury Laboratory, with remote participation via Zoom.

      • Approach to sustainability at DESY 20m

        DESY has a strong focus on sustainability for its machines, laboratories and the whole campus. Specifically, with the development of Petra IV a new revolutionary high resolution 3D X-ray microscopy, issues like energy efficiency and critical materials become more prominent. The talk gives a first overview of our concept for infrastructure and technical designs.

      • Is a Megawatt Accelerator sustainable? 20m

        PSI operates a cyclotron based proton accelerator facility with a beam power of up to 1.4MW for materials science. Being the most powerful proton driver of its kind, it is the most energy efficient at the same time. In this talk, the main power consumers of the accelerator complex are identified and possible improvements of the overall energy efficiency are discussed. The impact of the current energy crisis on the operation of the facility is addressed.

      • ISIS Sustainability- Progress and Future Plans 20m

        The ISIS facility recognises that it must embrace environmental sustainability if the facility and STFC are to achieve Net Zero. This talk outlines what ISIS has done and is planning to both reduce its carbon footprint and balance the Net zero equation.

      • A Green Next Generation Ion Beam Analysis Facility 20m

        Recent tests by the University of Jyväskylä and ISIS Low Energy Beams Group have demonstrated high-charge-state beams from a novel permanent magnet Electron Cyclotron Resonance (ECR) ion source. By using high-charge-state ions, lower voltages can be used to accelerate ions to the same energy. Using lower voltages eliminates the need for environmentally damaging SF6 high-voltage insulation. With STFC Horizons Program Net Zero funding, Daresbury Technology Department and ASTeC have built and tested a tuneable permanent magnet charge/mass separator dipole that will be tested with the ion source next year. Beams of 12+ argon, 19+ xenon, 24+ krypton have been demonstrated. These charge states are high enough to be used with a 500 kV air insulated high voltage platform to produce beams of the energies required for Ion Beam Analysis (IBA). The proposed SF6-free permanent magnet facility will use Time-of-Flight Elastic Recoil Detection Analysis (ToF-ERDA) for material characterisation, allowing measurement of the elemental depth profile in samples, which has a wide range of applications in materials science.

      • Permanent magnet technology for sustainable accelerators 18m

        Traditional resistive electromagnets are a major power draw in modern accelerators, in many cases permanent magnet technology may provide the solution. This talk outlines some of STFC's permanent magnet projects aimed at saving energy and making accelerators more sustainable to run.

      • Reduction in wall-plug power for high power RF systems 18m

        Most particle accelerators power budget is dominated by the RF system and hence efficiency of these are a key concern for the sustainability of future machines. The two dominant inefficiencies are the electrical efficiency of the RF amplifiers and the reflected RF power due to beam loading and microphonics. Cockcroft has been working with CERN to develop two key technologies to improve each. The first is the development of high efficiency klystrons that draw less beam power for a given output power. This is done via improved beam dynamics to create more ideal bunches. The second technology is fast reactive tuners, based on ferroelectrics, in order to have the cavity frequency shift very fast to follow transients reducing reflections.

      • Ground Water Cooling 18m

        Modern Particle Accelerators systems rely on a high degree of temperature stability. At Daresbury Laboratory, use of groundwater has the potential to improve facility and project sustainability by reducing refrigeration costs and increasing thermal efficiency using abstraction and recharge (injection) boreholes to feed heat exchanger cooling systems. In 2017, a project managed by Lisa Howard and sponsored by Andy Goulden was completed at the lab to confirm feasibility of the application, and has been used to inform the benefits of this presentation.

      • Accelerator impact review 15m

        The sustainable accelerator taskforce at Daresbury has spent the last few months analysing the carbon footprint of building and operating RUEDI, a relativistic ultra-fast electron diffraction and imaging facility. We aim to reveal the aspects of the accelerator that contribute most to the carbon footprint and focus on reducing the emissions from these areas, in order to make the biggest impact. The conclusions in the lifecycle analysis report we writing can be easily applied to other accelerator facilities. Today I will be giving an update on our progress so far and presenting our initial findings. The full report will be available to read in the new year.
