Dynamic environmental transmission electron microscopy
… of a dynamic environmental transmission electron microscope (DETEM) at the University of Illinois Urbana Champaign is documented in this thesis. The proposed apparatus is the first of its kind, combining the power of high-resolution electron imaging and diffraction of TEM, the time …

Determining molecular chirality with femtosecond LASERs
… on the order of 0.1%. <br/><br/>However the PhotoElectron Circular Dichroism effect first measured in 2001 exhibits a large asymmetry in the photoelectron angular distribution on the order of 10%. By coupling this PECD effect with multiphoton ionisation using femtosceond LASERs, it is possible to …

A scaler-based data acquisition system for measuring parity violation asymmetry in deep inelastic scattering
… measured at event rates up to 500 kHz with high electron detection efficiency and high pion background rejection capability. A specialized scaler-based counting data acquisition system (DAQ) with hardware-based particle identification was successfully implemented. The overall pion contamination …
