I finished the first version of the automation software to measure the ring down of the disk modes. I tested it with the new substrate that was installed yesterday. Here are some screenshots and a brief explanation of how it works.
It is based on a Python/Tk GUI, that can be launched on the workstation with the command ~/CRIME/crime.py
The main screen is similar to the following. Once a baseline spectrum is acquired, it is shown in the main panel:
The user should specify the folder and prefix of the result files, and other parameters related to the excitation. The when the "Excite and ring down..." button is pressed, here's what happens
At this point the amplitude of the peaks are continuosly monitored (every second) and thei amplitude shown in a new window. The user can select a subset of the modes for the plotting.
There are some wandering peaks in the spectrum, so some of the peaks aren't actually modes that get excited. This is easily fixed in the post processing of the results.
All peak amplitudes are saved to files in real time, so if you stop the GUI you'll have some partial results.
