摘要：

A cryogenic stage preamplifier for the TopHat experiment is built with InterFet NJ132L junction field effect transistors. We describe the testing procedure, screening, and fabrication of the six-channel preamplifier. It is attached to the LN2 shield and self-heats to 110 K with 20 mW total dissipation. The noise performance with grounded input is 7 nV root-mean-square (rms)/root Hz at 1.5 Hz and 1 nV rms/root Hz at 50 Hz. (C) 2001 American Institute of Physics.
