Abstract :
TPG is the acronym for Time Projection chamber with GEM amplification, hexaboard read-out and FADC electronics. We are constructing a TPG read-out module with three GEM foils (30 cm diameter) and a read-out board (30 cm diameter active surface) covered with hexagonal pads of 300 μm size. Aligned pads are connected in parallel to one strip out of three sets of parallel strips. Each strip is read by FADC electronics. The test bench for the TPG head will be the HARP-TPC field cage. TPG characteristics, design and expected performances are discussed.
