Popis: A polarized He-3 internal target was employed at the internal target facility of the Amsterdam electron Pulse Stretcher and Storage ring (AmPS) at the Dutch National Institute for Nuclear and High-Energy Physics (NIKHEF). The unique features of internal targets such as chemical and isotopic purity, high and rapidly reversible polarization, and the ability to manipulate the target spin orientation were successfully demonstrated. A nuclear polarization of 0.50 (0.42) at a He-3 gas flow of 1.0 (2.0) x 10(17) at s(-1) could be obtained. Operation at a nominal flow of 1 x 10(17) at s(-1) resulted in a target thickness of 0.7 x 10(15) at cm(-2) at a target temperature of 17 K. (C) 2000 Elsevier Science B.V. All rights reserved.
