A collaborative program is underway to field a comprehensive pump limiter experimental program on TEXTOR: Advanced Limiter Test-I (ALT-I). Either of two interchangeable limiter modules may be attached to an insertion/rotation mechanism to direct particles to the ∼1 m³ pumping chamber. Pumping is provided primarily by a solid getter assembly at ∼20,000 1/sec. Variation of geometric dimensions and gas puffing in the modules will allow the study of plasma and neutral interaction in differing recycle regimes. Multiple diagnostic systems are incorporated into the pump limiter design for use in conjunction with TEXTOR plasma diagnostics. Initial experiments are scheduled for December 1983.
