Abstract
The recent development of new processes has led to the fabrication of small density silica aerogel with high optical quality. The BaBar expe riment, in order to achieve its physics program, requires a good pion/ kaon identification capability up to 4.3 GeV/c able to work inside a 1 .5 T magnetic field. An aerogel threshold counter using the combinatio n of two refractive indices (1.055 and 1.007) can be used to complete the angular coverage of the particle identification system in the forw ard region. Different detector geometries read out by two photodetecto r types (fine mesh phototubes and hybryd photodiodes) have been consid ered and tested in a CERN beam test.
