An almost real time monitor of the blackbody radiation (BBR) shift in the optical clock IT-Yb1.
It reads the temperature from sensors and calculate the shift in real time (latency 80 s). The atomic coefficients used are those for Yb atoms.
Running the script will open a `matplotlib' figure that will update in real time. The script can be left running. To turn off the script simply close the figure.
The script requires the following python packages:
numpy,scipy,matplotlibpyvisa
It is set-up to read 10 Pt-1000 platinum resistance thermometers using an Agilent 34970A digital multimiter. Connection to the instrument is hard-coded.
