Strategies implemented in the operando infrastructure to mitigate radiation-induced effects. (a) Beam blocking between data acquisition. The radiation-induced oxidation of H3PO3 electrolyte in the presence of a thin Pt electrode, indicated by the decrease in the OCP (due to H2 generation), is minimized by a valve opening only during effective measurement times. (b) Example of a measurement system that requires a variation in the position of the irradiated sample, showing the alteration of the Ni L3-edge spectroscopic fingerprint of the NCA WE detailed in Section 2.3[link] (and at the O K edge, shown in the inset) when being irradiated three times consecutively at the same position, and the subsequent recovery of the spectroscopic signal when probing at a new sample spot that had not yet been exposed to the X-ray beam.
