Fast Processes in Scintillators
Development of new generation of accelerators for high energy physics with extremely high luminosity and new demands from medical imaging with PET requires fast scintillators with response of 10 ps. During last few years the physics of fast processes in scintillators attracts attention of the community. These processes include fast emission which occur in parallel with relaxation of electronic excitations (intraband luminescence, crossluminescence and other types of hot emission) and fast energy transfer to activators and new ways of fast creation of emission centers like capture of an electron by Ce4+ ions, and some other phenomena. The paper reviews the formation of scintillating signal in such systems.
