a, Relative temperature difference between PM box and heat exchanger, on 800 mK flange during a cooldown. The gray datapoints correspond to specific periods of pulse precooling and mixture condensation, where the temperature is unstable. b, Measurement of heating due to optical dissipation when the phase modulator is mounted on the 800 mK flange. c, Measurement of heating using a calibrated resistive heater mounted on the 800 mK flange.
