“…In [15] the effect of varying the beam aiming was explored showing an effect on the q-profile, but it did not consider transport. Reference [16] concluded that power requirements for a reactor may be satisfactory [37] and that stable profiles may be accessible. Generally, however, the large, energetic-ion orbits [15] make neutral-beam injection useful for affecting the profile across most of the radius but difficult to use for localized MHD-stability control or for control of tearing modes.…”

“…[22]. Briefly, experiments with neutral beams should anticipate the need to control the λ profile during buildup: without profile control, inductive drive alone does not yield a fully stable state in RFP's and stably decaying spheromaks eventually evolve toward strongly unstable states.…”

“…Unlike small tokamaks, spheromaks have beam access to achieve optimal aiming nearly parallel to field lines (cosθ ≈ 1), requirements being similar to those explored in mirror devices including the Field Reversed Mirror with coil geometry and goals similar to the spheromak discussed here [25]. The main cost for an experimental program to pursue these ideas could be avoided by sharing existing neutral beam systems employed in tokamak research [22]. For reactors, the beam power would generally be higher in spheromaks which have zero bootstrap current, compared to ARIES-AT that assumes 91% bootstrap current [18].…”
