1.4: Introduction to Atomic Absorption Spectroscopy
A magneto-optical trap MOT is an apparatus which uses laser cooling and a spatially-varying magnetic field to create a trap which can produce samples of cold, trapped, neutral atoms. Temperatures achieved in a MOT can be as low as several microkelvin , depending on the atomic species, which is two or three times below the photon recoil limit. A MOT is formed from the intersection of a weak quadrupolar spatially-varying magnetic field and six circularly-polarized red-detuned optical molasses beams. As atoms travel away from the field zero at the center of the trap halfway between the coils , the spatially-varying Zeeman shift brings an atomic transition into resonance which gives rise to a scattering force that pushes the atoms back towards the center of the trap.
Research and postgraduate teaching in toxicology is coordinated and led by the Toxicology Centre, with substantial participation from members of the University's Toxicology Group. The Toxicology Group is an interdisciplinary body under the umbrella of the College of Graduate Studies and Research that consists of faculty members from many university departments, as well as scientists from various government research institutions located on or near campus. Most Toxicology Group faculty are available to serve as supervisors for prospective students. The interdisciplinary nature of the program provides students with a diverse array of potential research opportunities in toxicology. Prospective students can apply to the program from such varied undergraduate backgrounds as agriculture, biology, chemistry, ecology, environmental sciences, medicine, physiology, pharmacology, toxicology, and veterinary medicine, to name but a few.
