Abstract
We have piloted mechanical compression of spinpolarized He-3 by a tita nium piston compressor. Questions of materials and design are discusse d, followed by a thorough investigation of relaxation sources in the c ourse of compression. The latter are traced mainly to regions with lar ge surface to volume ratio, through which fast passage is demanded, th erefore. We conclude from this feasibility study that polarized He-3 m ay be compressed this way up to many bars without serious polarization losses.
