    "abstract": "A detector designed to measure early particle showers has been installed in\nfront of the central CDF calorimeter at the Tevatron. This new preshower\ndetector is based on scintillator tiles coupled to wavelength-shifting fibers\nread out by multi-anode photomultipliers and has a total of 3,072 readout\nchannels. The replacement of the old gas detector was required due to an\nexpected increase in instantaneous luminosity of the Tevatron collider in the\nnext few years. Calorimeter coverage, jet energy resolution, and electron and\nphoton identification are among the expected improvements. The final detector\ndesign, together with the R$\u0026$D studies that led to the choice of scintillator\nand fiber, mechanical assembly, and quality control are presented. The detector\nwas installed in the fall 2004 Tevatron shutdown and started collecting\ncolliding beam data by the end of the same year. First measurements indicate a\nlight yield of 12 photoelectrons/MIP, a more than two-fold increase over the\ndesign goals.",
