Theoretical analysis has been carried out and test experiments have been implemented on the use of polychromatic synchrotron radiation to study fast processes in solids. The obvious benefits and challenges are outlined.
The operation of fusion reactor on the base of tokamak geometry of magnetic field is expected to be accompanied by pulsed heat loads to divertor. The loads lead to formation of plastic deformations and residual mechanical stresses. The stresses may result in mechanical destruction of tungsten armor of divertor. Typically it appears as a crack formation. The cracks decreases the heat removal...
At fast acceleration of metals, a cloud of microparticles (dust cloud) appears in front of the surface. Work on the study of these processes using Synchrotron Radiation (SR) was carried out at the Budker Institute of Nuclear Physics (Novosibirsk) [1,2].
In this work, the particle flux from shock-loaded tin was recorded using X-ray radiography, but also synchronously with another 4-channel...
The detector developments for fast and super-fast time-resolved studies at SR beams will be reviewed. Two detectors based on Si micro-strip technology are developed at present at Budker INP SB RAS. The detector for imaging of super-fast processes at a nanosecond scale, DIMEX-Si allows to improve by more than a factor of ten maximum detected photon flux, with respect to the gaseous version of...
