4. The experiments reported in T. Shikama et al., Nucl. Fusion 43, 517 (2003) measured the integrated voltage after a few hundred seconds and so integrator drift could not be distinguished from a small voltage at the output of the coil.

12. To reach similar conditions for coil B required currents in excess of the safe current carrying capacity of the (sealed) MIC to instrument cable junctions.
13. The core material used was >99.99%Cu. Nonuniform work hardening during MIC and coil manufacture could have contributed to the initial (relatively low) sensitivity.
