To meet the demands of laser-ion acceleration at a high repetition rate, we have developed a comprehensive diagnostic system for real-time and in situ monitoring of liquid sheet targets (LSTs). The spatially resolved rapid characterizations of an LST’s thickness, flatness, tilt angle and position are fulfilled by different subsystems with high accuracy. With the help of the diagnostic system, we reveal the dependence of thickness distribution on collision parameters and report the 238-nm liquid sheet generated by the collision of two liquid jets. Control methods for the flatness and tilt angle of LSTs have also been provided, which are essential for applications of laser-driven ion acceleration and others.

Drawing from the theory of territorial behavior, this article predicts the explanatory role of silence behavior in the relationship between knowledge hiding and hider's innovative behavior in Chinese organizations, and the potential of Zhongyong thinking in mitigating the detrimental effect of knowledge hiding. Results derived from a time-lagged and multi-source survey support our hypotheses. Specifically, knowledge hiding is negatively associated with the innovative behavior of the hider. Silence behavior mediates the relationship between knowledge hiding and innovative behavior. Meanwhile, Zhongyong thinking moderates the positive relationship between knowledge hiding and silence behavior, as well as the indirect relationship between knowledge hiding and innovative behavior through silence behavior. Theoretical and practical implications are discussed based on these findings.
