DOIAbstract
New flowing afterglow apparatus, Cryo-FALP, was built to study ternary Collisional-Radiative Recombination (CRR) of Ar+ ions with electrons in He/Ar afterglow plasma at temperatures 40–200 K. The obtained ternary recombination rate coefficient at 57 K is KCRR = (3 ± 1) × 10−17 cm6 s−1. It is the first time that the KCRR was measured below 77 K. The measured temperature dependence KCRR ~ T(−4.5 ± 0.4) is in a good agreement with theoretical prediction
