The method is based on the gas-phase chemical reaction between Cl2 and HI in a separate reactor. This process is easily scalable and can simplify the COIL operation by providing better control of I2 flow rate. A yield of l2 in the generation reaction up to 85% was achieved in a reasonable volume of the reactor. A small-signal gain up to 0.75 % cm-1 at temperature of 150 K in the center of supersonic cavity was measured. A comparison with the established evaporation way of I2 delivery confirmed that the chemical method has little or no impact on the COIL kinetics. The COIL output power measured with the chemical and evaporation methods was nearly identical at comparable conditions.
