Summary
• Proof of principle shown already last time.
• More photons: employ radiators with multiple
refractive indices. Idea successfully tested in beam
tests.
• Aerogel production: transmission length improved,
new cutting methods tested, multiple layer samples.
• R&D issues: development and testing of a
multichannel photon detector for high mag. fields
• mass production of large aerogel tiles
• readout electronics
