A {sup 3}He-{sup 4}He dilution refrigerator and polarizing solenoid have been built at Saclay, designed for experiments with the Fermilab polarized proton and antiproton beam (E 581/704). The polarized target volume is 3 cm in diameter and 20 cm in length. The refrigerator is of coaxial geometry with a central tunnel for the incident beam. The polarizing field strength is up to B=6.5 T with uniformity of {Delta}B/B{le}{plus minus}5 10{sup {minus}5} in the target volume. The temperature in frozen spin mode is 50 mK. The refrigerator and solenoid were tested at Saclay by polarizing a full load of pentanol beads before shipping to Fermilab in August 1988.
