• Hence, high throughput is a desired quality for microbeam systems.
• This discovery was made through observation after removing the pre-existing centrioles using laser microbeam.
• A virtual microbeam training course, complete with videos and handouts, is also available online.
• _Dr . Per Spanne, a pioneer in the field of microbeam radiation therapy and diagnostic X-rays.
• Microbeam techniques can overcome this limitation by delivering an exact number ( one or more ) of particles per cell nucleus.
• _Dr . Per Spanne, 53, a pioneer in the field of microbeam radiation therapy and diagnostic X-rays.
• RARAF was one of the first three microbeam facilities to be built, and it is the only original microbeam facility still in operation.
• RARAF was one of the first three microbeam facilities to be built, and it is the only original microbeam facility still in operation.
• The laboratory is also home to the Radiological Research Accelerator Facility ( RARAF ) a National Institute of Biomedical Imaging and Bioengineering biotechnology resource center ( P41 ) specializing in microbeam technology.
• In the new study, researchers from Columbia University used a device called a charged-particle microbeam, which is capable of irradiating individual cell nuclei with a specific number of alpha particles.
• Furthermore, particle microbeam studies show that passage of even a single alpha particle ( e . g . from radon and its progeny ) through cell nuclei is highly mutagenic, and that alpha radiation may have a higher mutagenic effect at low doses ( even if a small fraction of cells are hit by alpha particles ) than predicted by linear no-threshold model, a phenomenon attributed to bystander effect.
• The school's geochemical and mineralogical analytical laboratories include a ?.5 million microbeam analytical facility that contains an extensive range of sample preparation and analytical facilities including optical microscopes, cathodoluminescence, low-vacuum scanning electron microscope, electron probe microanalyser, QEMSCAN ( particle analysis and mineral identification ), X-ray fluorescence spectrometer, X-ray diffraction, atomic absorption spectrometers, atomic fluorescence spectrometer plus elemental, physical and thermal analysers.
