Abstract

We describe the design and construction of the first triple-GEM chamber prototypes for the TOTEM detector at CERN LHC. The chambers are semicircular, with an inner and outer radius of the active area of about 40 and 150 mm; six to eight detectors will be mounted on each arm. Each chamber has analogue readout of the charge on concentric circular strips, at 400 μm pitch, to obtain the radial coordinates, and about 1000 pads of sizes between 3×3 and 7×7 mm² with digital readout, used to generate the triggering in combination with the other chambers.
