Fabrication and characterization of multilayers for focusing hard x-ray optics
(Massachusetts Institute of Technology, 2002)This study investigated the growth of multilayers with depth-graded thicknesses and their performance as x- ray mirrors for the next generation of focusing telescopes. Different material combinations were studied for the ... -
Fast neutron resonance radiography for element imaging : theory and applications
(Massachusetts Institute of Technology, 2001)Fast Neutron Resonance Radiography (NRR) has been devised as an elemental imaging method, with immediate applications to detecting explosives and drugs in passenger suitcases. In the NRR method, the 2-D elemental mapping ... -
Fast-ion spectrometry of ICF implosions and laser-foil experiments at the omega and MTW laser facilities
(Massachusetts Institute of Technology, 2013)Fast ions generated from laser-plasma interactions (LPI) have been used to study inertial confinement fusion (ICF) implosions and laser-foil interactions. LPI, which vary in nature depending on the wavelength and intensity ... -
