  Micromegas is presently in use by many experiments providing enhanced
performance when used in high particle environment. Compared with other
solid-state detectors or conventional gas counters Micromegas is robust and
radiation hard. Recent improvements in the design and fabrication of low-cost
Micromegas have led to a significant step for readout of large volume
detectors. A novel Cherenkov counter with Micromegas photodetector readout is
proposed for on-line particle identification and trigger at high rates.
