| Title | 423: ITER shutdown with li control | ||
| Name: | T. C. Luce ( |
Affiliation: | General Atomics |
| Research Area: | ITER Startup, Shutdown, Vertical Stability | Presentation time: | Not requested | Co-Author(s): | -- |
| Description: | Normal shutdown of ITER scenarios has received virtually no attention either by simulation or experiment, yet it is perhaps the most likely time for the plasma to disrupt. This proposal entails looking at means to shutdown the various ITER scenarios without disruption. It includes li control by heating and current rampdown rate. | ||
| Experimental Approach/Plan: | In each ITER scenario, simulate the reduction in alpha power at end of burn by control of balanced NBI and add other heating sources by feedback control to stay in H mode and keep the plasma vertically stable. The current rampdown rate will also be controlled. | ||
| Background: | -- | ||
| Resource Requirements: | Need new feedback algorithm in PCS to simulate alpha power, maintain H mode, and control li simultaneously. | ||
| Diagnostic Requirements: | Only need RTEFIT parameters. | ||
| Analysis Requirements: | -- | ||
| Other Requirements: | -- | ||
