Which experiments are saved

Tha autosave button is the boxed disk on the top right next to the QUIT button.

It can be set to on or off image image and controls whether experiments are saved automatically after the measurement.

Note that continuous acquisitions cannot be saved, i.e. there is (currently) no way to save the N previous spectra seen in continuous mode.

What is actually saved

For each measurement (dataset), we have experimental information that is saved automatically without the need of user input (provided devices are connected):

  • Data: actual dataset
  • Name: experiment identifier (ex: 'NC01_spectrum_00')
  • Date: datetime at the end of the measurement (ex: '2021-07-05 10:00:00')
  • T_K: sample temperature (ex: 8)
  • EPow_uW: excitation power
  • Time_ms: acquisition time
  • WL_nm: wavelength calibration
  • Suppl: background acquired with shutter closed before each experiment
  • Suppl_2D: when relevant, this field contains information needed to interpret Data. For XYMaps, this field contains the center position and limits of the scan.
  • L2Exc_deg: excitation HWP angle
  • L2Det_deg: detection HWP angle
  • Att: piezo positioners readout
  • FSM: sterring mirror position
  • Marker: marker position
  • Detector: detector, can be 'CCD1D', 'CCD2D', 'APD1', 'APD2', 'APD1+2', 'PD1', 'PD2
  • Grating: SpectraPro monochromator grating

There are also some fields that need to be filled by the user. As explained here some fields need to be filled before running the program:

  • SamplePrep: sample preparation date
  • SampleOf: objects studied
  • SynthName: synthesis name
  • SynthTemp: synthesis temperature
  • SynthDilution: dilution level
  • SynthPolym: polymer used for dispersion
  • SynthPolymPerc: concentration of polymer used for dispersion
  • SynthSolv: dispersion solvent

Other fields can be filled during experiments or when changing experiment configuration:

  • Comment: comment added by operator before measurement (ex: 'new filter position' or 'retry same measurement')
  • ESource: excitation source, can be 'CW', 'P', 'SK'
  • EWL_nm: excitation wavelength
