ABSTRACT:
Collisions between electrons and neutral atoms or molecules play driving roles in the chemistry of a wide range of technological and natural environments. These include plasma manufacture of silicon devices, laser and gas discharges, auroral phenomena and medical techniques for treatment of cancer patients. While electron collisions research has long been at the forefront of technological innovations in these (and many other) areas, current experimental techniques remain limited in the targets processes they can consider, largely limited to targets with large vapor pressures and/or large cross sections. In this talk, I will describe new experimental techniques that will open up new avenues of research in scattering physics, primarily based around experiments using multi-hit detection imaging, magnetic guiding fields and time-of-flight energy detection. I will also discuss the application of these techniques towards a new experimental program considering biologically important molecules and neutral radicals.
