| 英文摘要 | Based on the Experimental Physics and Industrial Control System, a portable data-collection system for soft x-ray absorption spectroscopy has been developed at the BL02B and BL08U beamlines of the Shanghai Synchrotron Radiation Facility. The data-collection system can be used to carry out total electron yield (TEY) and total fluorescence yield (TFY) experiments simultaneously. The hardware consists of current preamplifiers, voltage-to-frequency converters, and a multi-channel counter, which are aimed at improving the signal-to-noise ratio. The control logic is developed using Python and Java. The novelty of this control system is its designed portability while being extensible and readable and having low noise and high real-time capabilities. The oxygen K-edge absorption spectra of SrTiO3 were obtained using the TEY and TFY technology at the BL02B beamline. Furthermore, the TEY and TFY spectra of the relaxor ferroelectric single-crystal of lead magnesium niobate-lead titanate measured by the present data-collection system have lower peak-to-peak noise amplitude than the ones measured by using a picoammeter. The experimental results show that the spectral signal-to-noise ratio recorded by the present system is 5.7-12.4 dB higher than that with the picoammeter detector. |
