Description
We present the detection of the Crab Pulsar above 25 GeV
by the 17m diameter MAGIC telescope. We observed the
Crab Pulsar between October 2007 and February 2008 using
a newly developed trigger system, which allowed us to lower
the energy threshold of the telescope from 55 GeV to 25 GeV.
From previous non-detections of the Crab pulsar above 55 GeV
and from the observations by the EGRET experiment below 10 GeV
it is known that the Crab pulsar shows a spectral turnover in
the energy region between 10 GeV and 55 GeV. We will
present the energy of this turnover as well as a comparision of the light
curve measured by our experiment with the one measured by
EGRET.
