Rez Mani did an M.Eng in Engineering Physics focused on optical properties of semiconductors from McMaster University in Hamilton, Ontario. This followed by a Ph.D. in Earth and Space Science focused on satellite optical instrumentation from York University in Toronto, Ontario. After working in the industry for 10 years where he participated in a multitude of optical/laser/spectroscopic projects, he returned to York University as a contract faculty and a research associate in 2011. He has also worked for Allied Scientific Pro as a consultant since 2011 and as an application scientist since 2017.
Space-born instruments carry many electronic devices including micro-processors, shift registers, op-amps, flip flops, etc. If a charged particle or an uncharged particle from space, strikes a sensitive node of an electronic circuit, it may cause a disruption or permanent damage. Testing of electronic circuits prior to space launch for radiation hardness is crucial to protect the electronic devices against this danger. Although testing in particle accelerator facilities produces absolute results for dosage of damage threshold, the process is expensive and can be done only in very localized test centers. The optical testing using near IR pulsed lasers using femto/pico-second pulse width and pico/nano joule pulse energy is much easier to set up and can be done at any location. The laser technique can focus on the device with submicron resolution. The optical method is unable to measure the absolute upset threshold but the laser upset threshold can be compared with the ion beam upset threshold. It is assumed that the relative differences remain the same throughout the measurements and hence all subsequent measurements can be done with the pulsed laser. Although the pulsed-laser method is compared to the radiation method, it is necessary to emphasize that it is not meant to replace it. Instead, the pulsed laser method is meant to be complementary to the radiation method.
About: Papers were solicited that demonstrate the impact of material studies – or studies of materials – on the conservation profession, including the emergence of innovative treatments, new ways of “looking” and “seeing,” shifts in decision-making and desired outcomes, and changes in collection care strategies. Also welcome were explorations of the impact of trending “materiality” studies on related disciplines including archaeology, museum and curatorial fields, and art history among others. Topics include, but are not limited to: cutting-edge imaging and analysis techniques of materials, new materials having conservation applications, revelations about the meaning and significance of materials within an artist’s work, and improved methods of authentication. Four concurrent general session sub-themes have been identified with more to be identified based on the submissions
When: May 29th - June 2nd, 2018
