Python software to determine pressure in diamond anvil cell experiments by Ruby and Samarium luminescence

Manual

[!IMPORTANT] All controls are available both in the left sidebar and within the menus, with the exception of the items in the Help menu, which are only accessible through the menu bar. The left sidebar can be hidden to maximize the size of the figures.

File

• Save
  • Save the data in txt, csv and npy format (wavelenghts, intensity), plus all the accumulations if the Measurement:Accumulation option is selected. Save the header in rtf format, with a resume of the performed analisys. Save the main figure in png format.
• Save Fit
  • WIP, not yet implemented
• Open File
  • Read data from file using the Rubycond Open File software
• Quit
  • Quit the main program

Spectrometer

• Calib Params
  • Opens the Calibration Parameters window to manually input data, manage calibration files (Open/Save), or edit the default settings. Click Accept when finished to confirm the new values.

• User Calib
  • Select to use the calibration
• Calibrator
  • Open the Rubycond Calibrator software
• Save as bkg
  • Capture the current spectrum to be used as a background reference
• Substract bkg
  • Enable background subtraction to remove the stored reference from the active measurement

Cooler :warning: Available only for Andor spectrometers.

Displays the target cooling temperature and the current temperature.

Measurements

• Snap
  • perform a single acquisition
• Acquire
  • start a continuos acquisition
• Int Time (s)
  • change the acquisition integration time in seconds, default value is 0.1 seconds
• Accumulation
  • change the number of accumulations, default value is 1

Fit

[!IMPORTANT] Fit are always performed to the data with Wavelenghts in cm⁻¹.

• Snap
  • perform a single fit
• Continuos
  • start a continuos fitting routine
• Function
  • Voigt
  • Gauss
  • Lorentz
  • Double Voigt
  • Double Gauss
  • Double Lorentz
• Bkg poly Degree
  • change the polynomial degree up to 7
• Min (nm)
  • Fit range minimum value. Click on the value to change it. If you click on the graph first, the value of the selected point will be suggested automatically.
• Max (nm)
  • Fit range maximum value. Click on the value to change it. If you click on the graph first, the value of the selected point will be suggested automatically.
• Iter Lim
  • The maximum number of iterations used in the minimization routine. The default value is 150
• Autoupdate
  • If not selected the Fit initial condition are automatically evaluated when the Fit range is changed (Fit:Min and Fit:Max), so not taking in account eventual changement in the afterwards acquired signal.
  • If selected the Fit results are used as the Fit initial condition in the next Fit.
• Report
  • Opens a window with the detailed fit report

Gauge

This menu allows to choose the gauge to be used and to change the default values for the reference wavelenghts and temperatures to be used both for Ruby and Samarium Sm²⁺:SrB₄O₇.

• Ruby Cr³⁺:Al₂O₃
  • λ₀ (nm) = 694.25
  • P Calibration
    • Shen 2020
    • Mao hydro 1986
    • Mao non hydro 1986
    • Dewaele 2008
    • Dorogokupets and Oganov 2007
  • T(λ₀) (K) = 298
  • T(λ) (K) = 298
  • T Calibration
    • Not Used
    • Datchi 2004
• Sm²⁺:SrB₄O₇
  • λ₀ (nm) = 685.51
  • P Calibration
    • Rashchenko 2015
    • Datchi 1997

Logger

WIP, not yet implemented

Tab Shortcuts

• List of available shortcuts
  Available layouts: QWERTY and AZERTY
  To switch layouts, uncomment the corresponding line (line 127 or 128). Default is QWERTY.

self.keyboard = 'QWERTY'#uncomment to select
#self.keyboard = 'AZERTY' #uncomment to select

QWERTY Shortcuts

ctrl + Z = Set Fit:Min as cursor
ctrl + X = Set Fit:Max as cursor
ctrl + C = Zoom to fit
ctrl + Q = Rescale to full scale
ctrl + F = Fit snap
ctrl + G = Fit continuos

ctrl + O = Open file
ctrl + S = Save file

AZERTY Shortcuts

ctrl + W = Set Fit:Min as cursor
ctrl + X = Set Fit:Max as cursor
ctrl + C = Zoom to fit
ctrl + Q = Rescale to full scale
ctrl + F = Fit snap
ctrl + G = Fit continuos

ctrl + O = Open file
ctrl + S = Save file

Tab Calc

• Let the user to perform simulations using different gauges, wavelenght, pressure and temperatures for Ruby and gauges, wavelenght and pressure for Samarium using the Ruby and Samarium pressure/wavelength calculator

Install

Use pip to install the program within a virtual environment (strongly recommended).
Here's a short tutorial on installing a virtual environment.

pip install rubycond

To update:

pip install rubycond --upgrade

Supported spectrometers

Ocean Optics and Andor spectrometers. To change spectrometer, uncomment the corresponding line (line 131 or 132). Default is OceanOptics.

self.spectrometer_model = "OceanOptics" 
#self.spectrometer_model = "Andor" 

Ocean Optics spectrometers

Install the python-seabreeze for the Ocean Optics spectrometers:

conda install -c conda-forge seabreeze
seabreeze_os_setup

Andor spectrometers

Using Andor spectrometers requires the purchase and installation of the official Oxford Instruments Software Development Kit (SDK).
