The Study of Supersonic COIL with Generation of Iodine Atoms from CH3I in DC and RF Discharges and New Methods of Active Medium Preparation

Abstract

The developed supersonic COIL with 5 cm gain length was driven by Verti Jet SOG having 0.28 liter of working volume. The oxygen was diluted by the primary nitrogen downstream from the JSOG. Two types of nozzles were tested: single throat nozzle with 10 mm throat height and double throat nozzle with total throat height 15 mm. The COIL with single throat nozzle operated at the primary nitrogen dilution O2:N2 = 1:1 and the chlorine flow rate less than 40 mmole/s to maintain the designed gas flow conditions in the reactor of JSOG. The maximum power 765 W has been achieved at 39 mmole/s of the chlorine molar flow rate. The using of double throat nozzle allowed to increase chlorine molar flow rate up to 75 mmole/s. In this case the maximum power 1.4 kW has been reached for primary nitrogen ratio O2:N2 = 1:1.28. The specific performances of 5 kW per 1 liter of the reactor volume, of 100 W/cm per unit of the stream cross section area in the cavity and of 2,7W/(liter/s) of the pump capacity were obtained.
