Quatratran - Helping to make The World a safer place
February 19, 2004Since the development of superconducting electronic devices there has been a need to develop a three terminal transistor like device sensitive enough to measure small voltage and current signals typical of those associated with single electron and photon events.
A group of researchers in the Department of Particle & Nuclear Physics at Oxford University has designed a superconducting device with properties analogous to those of a traditional semiconducting transistor. The Quatratran (Quasiparticle Trapping Transistor) has the ability to amplify small signals and also be utilised as an electronic switch. The Quatratran is sensitive enough to detect, and measure the energy of, single photons and hence has applications in infrared and X-ray astronomy, materials characterisation, and florescence measurements of biological samples.
With security being such an important issue at present, one of the most important potential applications of the technology is that it is capable of detecting nuclear radiation.
This technology is patent protected and anybody who is interested in finding out more about the technology should contact Isis Innovation Ltd to discuss it further.

Nuclear News and Current Nuclear Events RSSGetting to the Root of the Matter
Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a root system that makes it all possible. Roots provide anchor and support for plants, extract water and nutrients from soil, and reduce soil erosion.
Study shows how daughter is different from mother
The mother-daughter relationship can be difficult to understand. Why are the two so different? Now a Northwestern University study shows how this happens. In yeast cells, that is.
Improved technique determines structure in membrane proteins
Understanding the form and function of certain proteins in the human body is becoming faster and easier, thanks to the work of researchers at the University of Illinois.
Nature or Nurture-Are You Who Your Brain Chemistry Says You Are?
Researchers using positron emission tomography (PET) have validated a long-held theory that individual personality traits-particularly reward dependency-are connected to brain chemistry, a finding that has implications for better understanding and treating substance abuse and other addictive behaviors.
"Top Secret" Technology To Help U.S. Swimmers Trim Times at Beijing Olympics
Milliseconds can mean the difference between triumph and defeat in the world of Olympic sports, leading more trainers and athletes to look toward technology as a tool to get an edge on the competition.
Quantum chaos unveiled?
A University of Utah study is shedding light on an important, unsolved physics problem: the relationship between chaos theory - which is based on 300-year-old Newtonian physics - and the modern theory of quantum mechanics.
MDCT just as accurate as MRI in assessing myocardial infarction in emergency setting
Multidetector CT (MDCT) is just as accurate as MRI in assessing myocardial infarct size--an important predictor of clinical outcome-- in an emergency setting according to a recent study conducted by researchers in collaboration between the VA Medical Center in San Francisco, CA and the University Claude Bernard in Lyon, France.
Size-specific cracking shakes out at the nanoscale
Certain sizes of nanostructures may be more susceptible to failure by fracture than others.
Improved estrogen reception may sharpen fuzzy memory
Estrogen treatments may sharpen mental performance in women with certain medical conditions, but University of Florida researchers suggest that recharging a naturally occurring estrogen receptor in the brain may also clear cognitive cobwebs.
