Abstract

In view of low sensitivity of CCD arrays in the ultraviolet range, a new measuring method for ultraviolet spectrum with a 32-anode linear photomultiplier tube (PMT) array is presented. A spectrum measurement system that includes a spectroscopic design and data acquisition circuits, together with the system-controlling software, has been developed for the PMT array. Compared with a spectrometer which employs a back-thinned CCD with the highest ultraviolet sensitivity, experiments indicate that the system has the same sensitivity as the spectrometer which works at the integration time of about 2 s, while requiring less than 7 ms for one single measurement. It is able to perform timeresolved measurements even in weak light applications where CCD spectrometers need to work at long integration times.
