SCAPA Beamlines has an engineering program for addressing the regular operation of the facility (availability and reliability), the stand-by operation of the facility (SCAPA-Interlock-system), and the shut-down and maintenance (repair, access, and maintenance). We provide different working mode for users, which includes Alignment Mode (for experimental setup), Measurement Mode ( attenauted full power beam for beam diagnostics ) and Normal Mode (Full power shotting). We also provides both online diagnostics (Near Field Beam, Far Field Beam, Spectrum, Energy, etc) and offline diagnostic (Pulse Duration, Contrast Ratio, etc).
