| Research Abstract |
Diagnostics of the edge plasma density in the edge transport barrier region need high-spatial and high-temporal resolutions. In this study, a lithium beam emission spectroscopy with a high-temporal resolution was developed, in order to study the edge density behavior. As a result, the crash and recovery profiles due to the edge localized modes were observed by using the lithium beam diagnostic. It contributes the H mode study and the mitigation of the divertor heat load due to the modes.
