Physicists use plastics to detect radiation

22.11.2007
In applications ranging from hospital X-ray machines to instruments for astronomy, the standard way to measure the dose of radiation is to use a detector made from an inorganic semiconductor, such as silicon. It is not easy, however, to use this type of detector over large areas, and inorganic detectors are not flexible.

A team of researchers from the Department of Physics at the University of Surrey, led by Dr. Paul Sellin, has developed a new type of radiation detector made from a new type of plastic that conducts electricity. As the radiation dose increases, a greater current flows in the plastic detector, allowing an accurate measurement to be made. The research effort has received a boost recently in the form of a one-year research grant from the Science and Technology Facilities Council. The grant is being shared with Centronic Ltd., a Croydon-based company that manufactures and develops radiation detectors.

The Surrey team has published their preliminary findings in the prestigious international journal, Applied Physics Letters. Dr. Sellin and his collaborators in the Physics Department, Dr. Alan Dalton and Dr. Joe Keddie, have also filed a patent on organic radiation detectors with support from the University.

Dr. Sellin commented: “This successful research has grown from a collaborative effort drawing on our expertise in radiation detection and the experience within the Soft Condensed Matter Physics Group in making polymer films and understanding their properties.”

Dr. Keddie added, “Within the Physics Department, the Radiation Laboratories and the Soft Matter Laboratories have benefited from recent investment from government SRIF funding. This investment is clearly leading to exciting scientific results combined with a patent and further funding.”

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
