| Description: | Expand the regime of high beta-p noninductive (HBPNI) plasmas to lower q95, primarily by reducing the magnetic field strength. | ||
| Experimental Approach/Plan: | Thus far, the HBPNI discharges have been run with a single value of magnetic field (1.9T). Reducing the magnetic field should make interesting values of G (beta_N*H/q^2) more accessible. | ||
| Background: | It has been pointed out that the magnetic field is less important in maintaining confinement and noninductive current than is the total plasma current. Also, one concern about the HBPNI plasmas has been the relatively high value of q95, leading to G ~ ΒΌ G_ITER. A downward magnetic field scan will expand the HBPNI operating regime and make these plasmas more interesting. | ||
