Based on Marvin Johnson's recent note on EMI noise penetrating the cryostat wall, I have calculated the reference DC resistances and, assuming certain noise currents, the resulting wire noise. For single cryostat walls (even half inch) and very conservative noise assumptions, I find unacceptable wire noise. However, I am listing easy and inexpensive remedies.
