October 2021: Progress is ongoing in our current lab space in Searle Laboratory for constructing a new bonding chamber. The vacuum chamber will be used for studying atomic imprint crystallization and near-field depositions. Once installation is complete, this chamber will allow us to carry out experiments to create large area single crystals on amorphous substrates.
So far we've installed the horizontal and vertical sample manipulators, along with the gate valves, cryo pumps, and various viewports and other vacuum miscellany. Next to be installed are the turbopump and water cooling systems, and then the system is ready for use!
