NM1, NM2, NM3, NM4 files for H, D, T, and impurity thermal ions Additional information: iseq=Iso2 Li pellet at 5.0s This is a member of a supershot power and isotope scan at 1.6 MA 4.8 Tesla with Pb ranging from 3--> 22 MW. Beam injection ranged from balanced to slightly co-dominated; at some power levels different mixtures of co and counter-directed sources were injected to allow an assessment of the effect of toroidal rotation. The `deuterium' shots have Do -> D+ and typically contain 1-2% residual tritium. The 'tritium' shots have To -> (D+ + T+) and typically don't have more than 50% thermal tritium due to residual deuterium influx from the carbon limiter. This shot had deuterium NBI from 7 sources near 100kV.
