Sirius Synchrotron Light Source, a part of the Brazilian Synchrotron Light Laboratory (LNLS) within the Brazilian Center for Research in Energy and Materials (CNPEM), has recently provided in-house developed ionization chambers, which have been commissioned by the SESAME Synchrotron Light Source in the Middle East. This collaborative effort, spearheaded by Santiago J. A. Figueroa, Beamline Researcher at QUATI (QUick x-ray Absorption spectroscopy for TIme and space resolved experiments) Beamline SIRIUS, and Latif Ullah Khan, Beamline Scientist at BM08-XAFS/XRF beamline SESAME, has resulted in successful integration of the ionization chambers into SESAME's XAFS data acquisition system. These ionization chambers are featured with higher signal to noise ratio, higher TTL frequency (~ 500 kHz), higher saturation voltage and lower integration time, making possible XAFS in continuous scan mode rather than point by point data collection. This achievement marks a milestone, enabling the acquisition of high-quality XAFS data and enhanced the capabilities of BM08-XAFS/XRF SESAME. This was made possible with the kind support of the procurement section, scientific and administrative directors of the SIRIUS and SESAME.
This collaborative endeavor highlights the importance of international scientific partnerships, the value of knowledge-sharing, overcoming scientific challenges and potential for groundbreaking discoveries.
