Abstract: An electrometer includes an input terminal adapted to receive an input signal an ethernet terminal, a web server, and a microcontroller. The ethernet terminal is adapted to receive an ethernet cable such that electrical power is provided to the ethernet terminal. The web server is in electrical communication with the ethernet terminal, and is adapted to receive a command. The microcontroller is in electrical communication with at least one of the ethernet terminal and the web server, and is adapted to execute the received command.

Abstract: A method and robot-based automation system are provided for cryogenic crystal sample mounting, for example, for use for cryogenic crystal sample mounting in the x-ray crystallography station at an x-ray source. The system includes a robot arm carrying a handset. The handset includes a pair of elongated fingers for sample mounting, and each finger carrying a set of strain gauge arrays for providing force sensing. A slim finger design allows a sample mounting process with no interference with the beam stop, cryostreem and x-ray detectors. The handset can detect the contact force intensity and direction; provide a precise gripping action; and feel the results of the gripping. The finger design incorporates a mechanism to maintain the sample temperature well below the cryogenic safety margin for the crystal viability. A Dewar container is provided with an ice control system and liquid nitrogen flow control. A triangular sample magazine maximizes the Dewar space usage.
