【 摘 要 】

In the CLASP / CLASP2 experiments, the contamination control was conducted mainly for the purpose of preventing molecular contamination. In particular, the organic contamination was successfully prevented. However, in the CLASP observation, the Lyα intensity decreased due to water molecules. Thus, we obtained the importance to evaluate the influence of molecules that can be easily removed and to quantitatively evaluate the vent path during the flight.
