Аннотация:A method for measuring the bremsstrahlung X-ray spectra of the electrons accelerated
in laser plasma using Medipix matrices has been developed. In comparison with the
scintillators and photomultiplier detectors commonly used for such measurements, the use
of the matrix allows accumulating the spectrum in a much shorter time. This makes
possible dynamic control of the X-ray radiation characteristics and rapid adjustment of
the laser source parameters to obtain the maximum yield and energy of X-ray radiation.
The results of measurements of X-ray spectra on the ILC MSU terawatt femtosecond laser
complex for various laserÄplasma interaction regimes are presented.
