Temperature Control Script for Ultra-Stable Optical Cavity

This dataset contains a Python script implementing a proportional–integral (PI) control loop for stabilising the temperature of an ultra-stable optical cavity.

The script communicates with a multichannel power supply and a digital multimeter via PyVISA to regulate current through resistive heaters based on feedback from a 4-wire RTD sensor.

It is designed for laboratory use in precision frequency metrology experiments and includes logging, safety limits, and documentation to ensure reproducibility.
