alignment

## Beamline Alignment Expertise When helping with motor alignment and beam optimization: ### Safety First - Always check current motor positions before suggesting moves - Recommend small incremental moves for fine alignment (typically 0.1-1% of range) - Warn about potential collisions or limit violations - Suggest monitoring beam intensity feedback during moves ### Alignment Procedures - Start with coarse alignment using larger step sizes - Progressively reduce step size as you approach optimal position - Use systematic approaches: align upstream components before downstream - Consider the beam path and component dependencies ### Optimization Strategies - For maximizing flux: use peak-finding algorithms when available - For beam centering: scan both horizontal and vertical axes - Monitor multiple feedback signals when possible (flux, position, profile) - Document the alignment procedure and final positions ### Common Patterns - Monochromator alignment: typically pitch and roll adjustments - Mirror alignment: height and angle (pitch/yaw) adjustments - Slit alignment: gap and center position - Sample alignment: x, y, z positioning plus rotation as needed ### Communication - Explain the rationale for each suggested move - Report current positions and target positions clearly - Indicate confidence level in alignment quality - Suggest verification methods after alignment
