Outline of Final Research Achievements

We investigated fabrication and performance of superconducting tunnel junction (STJ) X-ray detector having silicon pixel absorber (SPA) to realize high sensitivity and high energy resolution in 2-4 keV soft X-ray region. One hundred STJ pixels are fabricated on the front side of a 400 micrometer thick Si substrate. SPAs are formed etching silicon substrate from the backside of STJ pixels. The depth of the silicon trench is 350 micrometer. Energy resolution of an STJ-SPA is 135 eV FWHM for 5.9 keV X-ray. The readout noise is 18 eV FWHM. By utilizing the SPA-STJ X-ray detector, it was succeeded to acquire X-ray absorption fine structure spectra of light element of Sulfur with a concentration of less than 0.1 atomic % in a soda lime glass.
