Ramp-Up of CHI-Initiated Plasmas on NSTX

Abstract: Without such impurity reduction, CHI initiated discharges could not have their plasma current increased by ohmic ramp-up, however CHI initiated discharges with reduced low-Z radiation can be ramped up by induction and exhibit higher plasma current than discharges without the benefit of CHI initiation.

“…2). This configuration is expected to be more robust against "absorber arcs," one of the primary failure modes for CHI startup [21]. In a typical CHI implementation, the current is driven along field lines connecting across one of the axisymmetric insulating gaps in the vacuum vessel.…”

“…The method of transient CHI has been successfully used on NSTX for an unambiguous demonstration of closed-flux current generation (namely a persistent I tor after I inj = 0) without the use of the central solenoid [22]. The CHI capacitor bank has several requirements on current, voltage, energy and current multiplication, which are discussed in detail in [23,24].…”
