Response time-improved, impurity-doped ZnO scintillator for precise synchronization of femtosecond pulses from XFEL and conventional ultrafast laser
Abstract
Response time of an Indium ion-doped zinc oxide scintillator is measured to be ~3 ps, an improved of almost 50 times compared to the previously reported Iron ion-doped counterpart. Intentional impurityion doping introduces additional fluorescence quenching channels that facilitate shortening of the response time. This improved response time allows timing control between x-ray free electron laser pulses and a femtosecond laser to within a few picosecond accuracy.
