We have developed atmospheric pressure microwave line plasma (APMLP) source of ~1 m in length. In this study, O radical density of APMLP is measured by vacuum ultra violet absorption spectroscopy (VUVAS) and O2 gas flow rate dependence of O radical density is measured. Furthermore, spatial dependences of O radical density along the long plasma is measured.
