Ophyd

ophyd is a Python-based interactive environment for instrument control at NSLS-II synchrotron beamlines.

Examples

• Motors
  • wh_pos() : motor positions
  • mov(dcm_x, 1.0) : move motor
  • movr(dcm_x, -1.0) : relative motion
  • movr([dcm_x, dcm_y], [-1.0,-1.0]) : multiple motions
• Scan
  • dscan.detectors : list
  • dscan(diff_xh, -1, 1, 25)
• EPICS
  • Access PVs:
    • caget()
    • caput()
  • Epics signals
    • eiger1M_exposure_time = EpicsSignal('XF:11IDB-BI{Det:Eig1M}cam1:AcquireTime', rw=True, name='eiger1M_exposure_time')
• Logging
  • grabit : screengrab, copied immediately to Olog notebook.
    • 'i' to enter interactive mode, type text, then to exit+save do 'Esc' then ':wq'.
