///"New  transition radiation detection technique based on DEPFET 
silicon pixel matrices"/

*Abstract*

Transition Radiation Detectors (TRD) have the attractive feature of 
being able to separate particles by their gamma factor.  Replacing the 
xenon based gaseous detectors by modern silicon detectors is complicated 
by the large energy losses of charged particles in 300-700 um of 
silicon. A silicon active pixel detector (DEPFET) allows a new detection 
technique to be used, in order to overcome the existing limitation on 
the separation of signals of transition radiation photons from  dE/dx 
signals from а charged particle in the same pixel. The tests of DEPFET 
with fiber radiator have been carried out at CERN SPS and DESY beams. 
The first results of test-beam measurements and Monte Carlo simulation 
will be presented.
