Device and handling system for measurement of mobility and sheet charge density

A device for measurement of mobility and sheet charge density in conductive sheet materials, comprising:

• a microwave source;
• a first waveguide positioned to receive microwave power from said microwave source;
• an adjustable mount adapted to adjustably position a sheet material item at a plurality of measurement locations to receive microwave power transmitted from said first waveguide;
• a magnet positioned to induce a magnetic field at a test location;
• a first detector to detect the power of the microwave power source;
• a second detector to detect the power of the microwave power reflected from a sheet material item in a measurement location from the plurality of measurement locations;
• a third detector to detect a Hall effect microwave power,
• wherein said adjustable mount further comprises a first end effector adapted to position said sheet material item at the plurality of measurement locations to receive microwave power transmitted from said first waveguide, said first end effector being movable between an adjustment position and a test position, wherein said adjustment position is a position at which the rotational position of the sheet material item is selectably adjustable, and said test position is a position at which at least one test can be performed on the sheet material item using the first waveguide,
• wherein the device further comprises a rotator-lifter for engaging said sheet material item and moving it along a second axis substantially perpendicular to a longitudinal axis of said first end effector, the rotator-lifter further configured to rotate about the second axis using a first motor unit,
• wherein said first end effector and said rotator-lifter each comprise at least one vacuum element for engaging said sheet material item.
