| Title | 146: Burst Disk Gas Jet for Disruption Mitigation on DIII-D | ||
| Name: | Larry R. Baylor ( |
Affiliation: | Oak Ridge National Laboratory |
| Research Area: | Disruptions | Presentation time: | Requested | Co-Author(s): | T. Jernigan, P. Parks, E. Hollman, S. Combs, C. Foust |
| Description: | A new multi-valve gas jet system that uses burst disks at the exit of the valve is proposed to enable high gas flow rates. This system is under development now at ORNL and if tested successfully in the lab it could be employed in 2008 for use on DIII-D. | ||
| Experimental Approach/Plan: | The experiments would be similar to the previous gas jet disruption mitigation experiments. Total flow would be limited to 2000 torr-L to minimize NBI interaction. | ||
| Background: | The use of gas jets for disruption mitigation was pioneered on DIII-D. A limitation of the technique is the conductance of the tube that the jet must flow in. A test of the highest possible gas jet flow rate is needed to compare with theory. The proposed burst disk system will enable that test. | ||
