A beam loss in the superconducting part of SNS linac has been observed during its commissioning and operation. Although does not prevent high power operation, it results an almost uniform irradiation components increased radiation levels tunnel. Multi-particle tracking could neither account for magnitude nor dependence on machine parameters. It was recently found that is consistent with intrabeam particle collisions resulting stripping H- ions. The paper describes experimental observations corresponding analytical estimates stripping.
