Abstract
A high-speed wavelength-dispersive ion beam induced luminescence (IBIL) detector was demonstrated using a newly developed photon-counting mode spectrometer based on a 32-channel photomultiplier tube (PMT) array combined with a high-efficiency optical grating. An integrated electrical circuit based on a field-programmable gate array was prepared to process 32 individual IBIL signals from different PMT channels. These signal were further processed conventionally by a micro-PIXE analysis system. Individual pulses corresponding to each IBIL photon incident from the PMT array were multiplexed into a single analog chain with different amplitudes corresponding to the channel number of the array. The signal had a pulse width of 2μs in the amplitude range 0–10V. The results suggest that the demonstrated IBIL detector can be used to detect differences in IBIL images at multiple wavelengths.
