The scripts for the PSOMA cryostat model can be found in mariner40/CryoEngineering/ (can be moved to somewhere more fitting). There are 2 scripts: PSOMAstatParams.ipynb (for specifiying physical system parameters) and PSOMAstatCooldownEstimation.ipynb (for simulating the model). I used the tentative parameter values and geometry found here: https://dcc.ligo.org/LIGO-D2100770.
Attachment 1 shows the resulting cooldown curves. The system is being cooled by a LN2 resevoir fixed at 77K. The model has been handed off to Aaron for testing and tweaking of parameters.
