Abstract
Plasma is produced by a microwave surfaguide/1/ in a cylindric quartz cell filled with helium at a pressure of 14 torrs. A homogeneous plasma is so obtained along the axis. Spectroscopic diagnostics are used to measure during the first 100 µ s and in different parts of the cell : a. different atomic and molecular excited levels populations b. the rotational temperature of He2 in two electronic states e3πg and E1πg c. a mean electronic temperature of the class of electrons which recombine.
