Cooling of the xenon nozzle flow to T = 230 K produces three leading effects. They are (1) a ~2.5-fold enhancement of the Xe(L) hollow atom emission on the single-vacancy 3d → 2p charge state arrays, (2) the production of amplifying self-trapped plasma channels with significantly enhanced lengths and (3) very sharply augmented emission on (2\overline {\rm s} 2\overline {\rm p}) Xe(L) double-vacancy transitions in the λ cong 2.80 Å region.
