High pressure helium arcs are created in linear flashlamps. Plasma diagnostics taking into account non-ideality effects, give on axis electron densities in the range 2 10{sup 17}-1.7 10{sup 18} cm{sup -3} and temperatures included between 20000 and 30000 K. In these conditions of dense plasmas, profiles of emitted neutral lines are recorded and compared with other experimental values and theoretical calculations.
