| Title | 328: Fast wave heating and current drive in AT plasmas | ||
| Name: | Masanori Murakami ( |
Affiliation: | Oak Ridge National Laboratory |
| Research Area: | Core Integration (Steady-State Scenario) | Presentation time: | Not requested | Co-Author(s): | C. Petty, R. Pinsker, W. Heidbrink, W. Baity, and Adv. Scenario Develop groups |
| Description: | (1) Robust coupling to AT plasma
(2) Characterize beam ion absorption of FW power at 90HZ and 60MHz (3) Validate scenario modeling of FWCD in AT | ||
| Experimental Approach/Plan: | 1) Reproduce shot #123159 and/or baseline NBI-plasmas ) [BT=1.85T, Ip=1.2 MA,nebar=3.5e19, NB=9.3 MW]
2) Study q0 control using co- and counter-FWCD in the AT plasmas. 3) Use PCS control of q0 if available. The push-pull operation with two ICRF systems is highly desirable. | ||
| Background: | |||
| Resource Requirements: | Machine Time:1 day Experiment; after successful demonstration of FWCD in AT plasmas (for ICRF and PCS operation); minimum residual hydrogen
Number of gyrotrons: 4 Number of neutral beam sources: 5 | ||
| Diagnostic Requirements: | Fast ion diagnostic (UC, Irvine), edge reflectometer (UCLA) | ||
| Analysis Requirements: | CURRAY/ONETWO, TRANSP, ONETWO; SciDAC-RF [AORSA/CQL3D; ORBIT-RF/TORIC, etc]; RANT3D | ||
| Other Requirements: | Fast wave systems (90 and 60 MHz) required | ||
