[1] Temperature measured with heat load
applied @ cryocooler cold tip with no cold tip attachments, @ 60 Hz power, @ room ambient
(19-25 C), with full radiant heat shield attached to 1st stage,
with no additional applied 1st stage heat load, high vacuum
insulation (starting vacuum <10 mtorr w/ < 5 mtorr/min
rate-of-rise), 10' flexhoses. 50 Hz reduces capacity
