Popis: A frozen spin polarized proton target has been developed and used at LAMPF to measure the spin correlation parameter ASS for proton‐proton elastic scattering. The target consisted of a horizontal dilution refrigerator, superconducting magnet, plus other equipment. The target refrigerator was fixed and the magnet moved on a rail system. The design permitted the same magnet to be used for both the polarizing and holding functions. In the holding configuration the magnetic field at the target was about 3 kG, and the open angular region for detecting scattered particles was 0° to 90° lab. With ethylene glycol target material a typical holding time of 500 hr was observed.
