Description
The Cherenkov light flashes produced by extensive air showers are very
short in time. A high bandwidth and fast digitizing readout, therefore,
can minimize the influence of the background from the light of the night
sky, and improve the performance in Cherenkov telescopes. The time
structure of the Cherenkov image can further be used in single-dish
Cherenkov telescopes as an additional parameter to reduce the background
from unwanted hadronic showers. A description of an analysis method
which makes use of the time information and the subsequent improvement
on the performance of the MAGIC telescope (especially after the upgrade
with an ultra fast 2 GSamples/s digitization system in February 2007)
will be presented. The use of timing information in the analysis of the
new MAGIC data reduces the background by a factor two, which in turn
results in an enhancement of about a factor 1.4 of the flux sensitivity
to point-like sources, as tested on observations of the Crab Nebula.
