New Specimen Prep Capability: CHESS has added an MBraun Labmaster glovebox to its suite of sample preparation facilities. The new glovebox provides users with an air and moisture free environment to store and prepare air sensitive samples for measurement at CHESS. Currently the glovebox provides a dry nitrogen environment; however, future upgrades will allow users to select nitrogen, argon, or helium environments dependent upon experimental needs. During the fall x-ray running period the glovebox was installed and commissioned MBraun and tested by two local Cornell experimental groups. The Abruña Group, from the Department of Chemistry, used the glovebox facility to load a custom battery cell for real time diffraction experiments during battery cycling. The Robinson Group, from the Department of Materials Science and Engineering, used the glovebox to initiate a chemical transformation reaction for real time wide angle x-ray scattering measurements during the chemical transformation. The glovebox will be available to all CHESS users in 2014.
