mahos_dq.meas.odmr.ODMR

class mahos_dq.meas.odmr.ODMR(gconf: dict, name, context=None)

ODMR (Optically Detected Magnetic Resonance) measurement.

This Node is for frequency-sweep, CW and Pulse ODMR measurements for defect qubits using non-imaging, single-pixel photodetectors. See PODMR or SPODMR for pulse ODMR measurements (Rabi, FID, SpinEcho, etc.) with fixed frequency. See IODMR for frequency-sweep, imaging CW ODMR with camera.

There are two options for the worker (sweeper, measurement logic). See docs of sweeper below for sweeper parameters.

• Sweeper : fast logic with hardware trigger.

• SweeperOverlay : interface to overlay.

Parameters:

• target.servers (dict[str, str]) – InstrumentServer targets (instrument name, server full name). Required keys (overlay mode): sweeper. Required keys (direct mode): sg, pg, and names in sweeper.pd_names. In direct mode, if sweeper.pd_analog is True, the key named by sweeper.clock_name is also required. Optional keys: pg in overlay mode (for non-PG overlays) and switch keys listed in switch_names.

• target.tweakers (list[str]) – The Tweaker targets (list of tweaker full name).

• target.log (str) – The LogBroker target (broker full name).

• switch_names (list[str]) – Optional switch instrument names to route signal/optical paths.

• switch_command (str) – Switch command label passed to Switch worker.

• pub_interval_sec (float) – Maximum interval between periodic status/data publications.

• fitter.dip (bool) – (default: True) True if ODMR shape is dip instead of peak.

• fitter.n_guess (int) – (default: 20) Number of data points in peak center guess.

• fitter.n_guess_bg (int) – (default: 40) Number of histogram bins in background guess.
