The 2026 Physics World Instrumentation & Vacuum Briefing: A Deep Dive into the Future of Measurement and Therapy
The latest issue of the Physics World Instrumentation & Vacuum Briefing is a treasure trove of insights into the cutting-edge world of measurement and therapy. This free-to-read briefing takes us on a journey through the latest advancements in quantum sensors, cell separation technology, radiotherapy monitoring, and particle acceleration, all while exploring the quirks of the International System of Units (SI).
One of the most intriguing topics covered in the briefing is the world of quantum sensors. While physicists have made remarkable strides in developing quantum sensors, many of these technologies remain confined to the lab due to the challenges of miniaturization. Florence Concepcion, from the UK-based firm Aquark, is on a mission to revolutionize this field. She discusses her efforts to reduce the size and energy consumption of ultrahigh vacuum (UHV) systems, which play a crucial role in quantum sensors based on cold atoms. This is a fascinating development, as it could pave the way for more practical and accessible quantum sensors, potentially revolutionizing fields like navigation and medical diagnostics.
Another highlight is the exploration of cell separation technology. Luke Cox, co-founder of Impulsonics, introduces a groundbreaking system that uses ultrasound to gently separate living cells. This is a significant advancement in biology and medicine, as traditional methods often involve harsh chemicals that can damage cells. By using a non-invasive approach, Impulsonics' technology has the potential to unlock new possibilities in cell research and therapy, offering a more gentle and effective way to study and manipulate cells.
The briefing also delves into the world of radiotherapy, where DoseOptics, co-founded by Brian Pogue, has made a remarkable breakthrough. Their system detects the faint Cherenkov light emitted when a radiotherapy beam strikes a patient's skin, allowing for real-time monitoring. This innovation ensures that the beam accurately targets the intended tissue while avoiding healthy areas, a crucial aspect of effective radiotherapy. It's a testament to the power of technology in improving patient outcomes.
In the realm of particle acceleration, researchers in the US have achieved a significant milestone by creating a compact free electron laser driven by a laser plasma accelerator (LPA). This breakthrough not only demonstrates the potential of LPA technology but also opens up new avenues for research. The LPA-driven laser has been used to generate a beam of muons, a fascinating development that could have far-reaching implications in particle physics and materials science.
Lastly, the briefing takes a whimsical turn as it explores the quirks of the SI system. Ben Stein from the US National Institute of Standards and Technology delves into the origins of the candela, which was derived from the brightness of a candle made from whale fat and beeswax. This is a fascinating historical detail that highlights the human element in the development of measurement standards. Additionally, the ongoing debate about using the dimensionless radian as the SI derived unit for planar angle adds a layer of complexity and intrigue to the world of metrology.
In conclusion, the 2026 Physics World Instrumentation & Vacuum Briefing is a must-read for anyone interested in the future of measurement and therapy. It offers a comprehensive look at cutting-edge technologies, from quantum sensors to cell separation and radiotherapy monitoring. The exploration of the SI system's quirks adds a touch of historical perspective, reminding us of the human ingenuity and collaboration that underpin the advancement of science and technology. This briefing is a testament to the power of innovation and the endless possibilities that lie ahead in the world of measurement and therapy.
