H01.00001: SRF Cavity Development for Lower Cost and Sustainable Accelerators Invited Speaker: Anne-Marie Valente-Feliciano Superconducting radio-frequency (SRF) cavities are building blocks of modern particle accelerators for fundamental research. They are typically made of high-purity bulk Nb, requiring cooling at around 2 K for efficiency. The size, cost and complexity of the associated sub-cooled LHe cryoplant has limited the application of SRF technology mostly to large machines. Beyond large scientific instruments, particle accelerators have many industrial and societal applications. Examples include environmental remediation (water, waste treatment), medical instrument sterilization, medical isotopes production, engineering of material and surfaces with altered properties radiation driven chemistry, food preservation... These applications need a new class of compact, high-power electron accelerators, with drastically reduced cryogenic requirements so they can be located on a mobile platform, in a university or hospital room. |

H01.00002: Sustainable Accelerator R&D Invited Speaker: Ben Shepherd Accelerators are energy-hungry facilities, and also consume a large amount of material resources. STFC's Accelerator Science and Technology Centre (ASTeC) has recently instantiated a Sustainable Accelerators Task Force, with the remit to make accelerators more energy efficient and environmentally sustainable. Several of ASTeC's activities in this area are presented here. We are undertaking a complete lifecycle analysis of accelerators, encompassing each phase of accelerator design, construction, operation, maintenance, and final decommissioning, breaking down each individual subsystem, assessing the facility's overall carbon footprint, and identifying areas where significant savings can be made. The findings are intended to be applicable to a wide range of accelerator facilities; we are using a planned mid-range facility, RUEDI, as a case study. |
