Abstract
This paper describes the entrance detector of the magnetic spectrometer PRISMA recently installed at Legnaro. The detector is based on rectangular ( 80 × 100 mm 2 ) Micro-Channel Plates (MCP). It provides a fast time signal and its position-sensitive anode allows to extract the X and Y information. It exploits an electrostatic field for the acceleration of secondary electrons from a thin Carbon foil ( ≃ 20 μ g / cm 2 ) onto the MCP assembly. The electrons are guided by a parallel magnetic field. Good performances were obtained in the laboratory tests. The detector is presently installed at the entrance of PRISMA and gives resolutions ⩽ 400 ps in time, and 1 mm in both X and Y -axes, with efficiency ≃ 100 % , in typical experiments with heavy-ion beams.
