Philippe Collon
The Physics & Astronomy Colloquium Series presents Philippe Collon of the University of Notre Dame , on “Developing Accelerator Based Archaeometry Analysis Techniques at the NSL” on Friday, Sept. 25, at 4:10 p.m. in Walter 245.
Abstract: Recently the nuclear physics laboratory has provided a host of analysis techniques through the use of accelerated ions beams from our small to mid-sized single ended and tandem electrostatic accelerators. The capability to deliver well focused accelerated particles as well as the development of a number of nuclear detection techniques that allow the identification of trace elements to a very high degree of sensitivity have opened the door to the precise elemental determination of varnishes, pigments and various materials but also the determination of both the origin and age of materials through the use of isotopic compositions and radioactive clocks. Some of these techniques also find applications in the “world” of nuclear astrophysics where their unique sensitivity provide important tools to study questions related to galactic radioactivities, supernova remnants and early solar system formation.
The talk will present the development of both a Proton Induced X-ray fluorescence Emission (PIXE) program and an Accelerator Mass Spectrometry (AMS) program in the Nuclear Science Laboratory at the University of Notre Dame.
