Unraveling the internal kinematics of open clusters is crucial for understanding their formation and evolution. However, there is a dearth of research on this topic, primarily due to the lack of high-quality kinematic data. Using the exquisite-precis

Neutron/x-ray combined radiography can integrate the merits of x-ray and neutron radiography and have an enhanced non-destructive detecting capability compared to single neutron or x-ray radiography. In this work, magnifying neutron/x-ray combined ra

Fast neutron radiography (FNR) using divergent neutron beams has the characteristic to magnify small cracks in low-Z materials. For such magnifying FNR systems, a simple method was developed using Monte Carlo simulations to estimate the spatial resol
