Time of Flight Elastic Recoil Detection Analysis with a position sensitive detector
A position sensitive detection system based on the microchannel plate detector has been constructed and installed at the existing Time of Flight (TOF) spectrometer in order to perform a kinematic correction and improve the surface time/depth resolution of Elastic Recoil Detection Analysis (ERDA) system. The position resolution of the detector has been tested for different types of ions and anode voltages. Time of flight spectra of recoiled O ions from SiO2 and F from CaF2 were collected in coincidence with position sensitive detector signal. Kinematic correction of time of flight spectra improved surface time/depth resolution by ~20% for our system, however even higher improvements could be obtained in larger solid angle TOF-ERDA systems.
