Description
Cathode electrodes of the Si(Li) detector elements of the SIXA X-ray spectrometer array are formed by gold-palladium alloy contact layers. The equivalent thickness of gold in one element was measured by observing the characteristic L-shell X-rays of gold excited by monochromatised synchrotron radiation with photon energies above the L3 absorption edge of gold. The results obtained at four different photon energies below the L2 edge yield an average value of 22.4±3.5 nm which is consistent with the earlier result extracted from detection efficiency measurements.
