    • note
    • In an adiabatic experiment, one might suspect spurious results if the temperature regulation of the adiabatic shield lags or overshoots during a first-order-like transition. Our experiment uses a computer-controlled regulator with nanovolt preamplifiers and full input/output optical isolation. The error (difference between the setpoint and the thermocouple signal) is recorded. It recovers from a 100:1 change in the heating rate in 10 seconds. During the flux line lattice melting transition, the maximum change in dT/dt is only 1.0025:1. The transient error does not peak out of the 2 nV rms noise (75 μK at 78 K). The thermal conductance of the heat links between the adiabatic shield and the sample holder is 28 μW/K at 78 K. This causes 2.1 nW noise in the heating power, to be compared with the electrical heating power 0.14 mW at 78 K when dT/dt = 14 mK/s. The relative error on the heat capacity due to transients is therefore less than 15 ppm, well below the amplitude of the specific heat peak (0.25% of the total heat capacity, including the sample holder, in 16 T).
