9th May 2022 – Terahertz Radiation

T-Rays  – A new research tool from the electromagnetic spectrum.

We are pleased to welcome Dr Darren Graham of the Photon Science Institute at the Department of Physics and Astronomy, University of Manchester and the Cockcroft Institute of Accelerator Science at Daresbury Laboratory, who will talk about his work in the exciting new area of Terahertz Radiation. In his own words:

“You’ll have heard of radio-waves, micro-waves, visible light and x-rays but probably not T-rays (or Terahertz Radiation). 

It fits between the microwaves and infrared part of the spectrum, and of course they have always been there. But only over the last 20 years or so have ways been found to create and control them artificially.

 Now new research areas are opening up using T –rays including:

  • medical imaging as a safer alternative to x-rays;
  • security scanning – for example at airports to detect concealed weapons remotely;
  • compact particle accelerators;
  • ultra-high speed communications;
  • process control in manufacturing. “
