Descripción
We report the development of a fast rotating target system to produce ultrashort incoherent X-ray pulses from Bremsstrahlung. These ultrashort X-ray pulses are produced in the laser-plasma interaction of solid metallic targets with 35fs, 1mJ pulses centered at 800nm of a 1kHz repetition rate Ti:sapphire laser.
We describe the experimental issues of the system such as the stability of the rotatory target or laser focusing with a small Rayleigh length (<20μm) which can modify the laser intensity on target and change the characteristics of the X-ray source.
We also report the X-ray spectra analysis of different metallic targets. We observe the X-ray source has a broad Maxwellian-like distribution with temperatures of around 10–120keV. These kind of X-ray sources could be used for advanced X-ray imaging such as absorption or phase contrast tomography.
