    Abstract

    We measured the magnetic noise generated by three small Stirling coolers (cooling powers 0.5 to 1.5 W at 80 K). Such a cooler will be used for cooling a high-Tc SQUID magnetometer. The measurements were performed with a fluxgate magnetometer and a 3-axis low-Tc SQUID magnetometer, the latter in a magnetically shielded room. The measuring setup is shortly described, and results on the coolers are given and compared to a simple dipole model. Consequences for SQUID-cooling are shortly discussed.
