The MALTA monolithic active pixel detector is developed to address the challenges anticipated in future high-energy physics detectors. As part of its characterization, we conducted fast-timing studies necessary provide a figure merit for this family has metal layer front-end electronics, and conventional laser technique not suitable fast timing due reflection from metallic surface. X-rays have been employed as more effective alternative penetration through these layers. triggered X-ray set-up designed study measurements response characterized using an LGAD. MALTA2 detectors studied, best time measured at about 2 ns.
