Fenker, Howard

The Gas Electron Multiplier (GEM) is a novel device which provides gas avalanche multiplication without a reliance on precision mechanical structures or microfabricated surfaces. It is not difficult to imagine using it to build a drift chamber, a cathode strip chamber, or a combination of the two in geometries which would be challenging for more conventional wire chamber techniques. This report provides a description of the device, a draft implementation of a GEM for a Region-1 tracking upgrade in CLAS, and a summary of the properties of such a system.
