| Title | 460: Performance sensitivity studies of steady-state scenario (low rotation, Te~Ti) | ||
| Name: | Edward Doyle ( |
Affiliation: | University of California, Los Angeles |
| Research Area: | Core Integration (Steady-State Scenario) | Presentation time: | Not requested | Co-Author(s): | -- |
| Description: | To date, work in the steady-state area has concentrated on obtaining an existence proof of the ITER Q=5 goal, i.e. G=0.3 coupled with 100% NI operaton. Now that this goal is close to achievement, it is an appropriate time to turn to the question of the extrapolability of these regimes to reactor conditions, specifally low rotation (low Mach no.) and Te/Ti~1. Specifically, attempt to perform Mach. no. scan, coupled with maximizing Te/Ti | ||
| Experimental Approach/Plan: | As was done for previous similar hybrid studies, select target plasmas to minimize power requirement for the "steady-state" phase. This is required in order to free NBI and ECH power for use in a Mach no. scan and as electron heating. Ths implies operation at as low a B as possible, and probably q_min~1.5. | ||
| Background: | This experiment addressed IEA/ITPA joint experiments on operation with low momentum input and Te~Ti | ||
| Resource Requirements: | 7 NBI sources, 5-6 gyrotrons | ||
| Diagnostic Requirements: | -- | ||
| Analysis Requirements: | -- | ||
