摘要：
We have built a 36-pixel superconducting tunnel junction X-ray spectrometer for chemical analysis of dilute samples in the soft X-ray band. It offers an energy resolution of similar to 10-20 eV FWHM below I keV, a solid angle coverage of similar to 10(-3), and can be operated at total rates of up to similar to 10(6) counts/s. Here, we describe the spectrometer performance in speciation measurements by fluorescence-detected X-ray absorption spectroscopy at the Advanced Biological and Environmental X-ray facility at the ALS synchrotron.
