Abstract

The structure of the calorimeters built with the "Shashlik" technique allows the insertion of tracking detectors within the sampling structure, in order to improve the accuracy in the determination of the showering particle direction and to enhance the e-π separation ability. The new luminosity monitor of the DELPHI detector at LEP was equipped with two planes of silicon pad detectors placed at a depth of 4 and 7.4 radiation lengths. A description of the silicon detectors is given, together with the results from the exposure to a test beam.
