🧊 Dilution Refrigerator: Wiring Heat Load, Cooling Power and Stage Temperatures (2D)

Side view of a five-stage dilution refrigerator. Set the number of wiring lines and their conductivity, the helium-3 circulation rate, the heat leak and dissipation at the mixing chamber and the still heater, and see each plate settle where its cooling power balances the wiring heat. Cooldown and base temperature are computed, with four in-page numerical checks. A thermal companion to the 3D cryostat.
