GAMMA 10/PDX has a divertor simulation experimental module (D-module) for detached plasma studies in the end region. To investigate the effect of suddenly changing the higher-density particle flux into the detached plasma condition, similar to edge-localized mode simulations, we performed supersonic molecular beam injection (SMBI) and electron cyclotron heating (ECH) experiments to produce a higher-density and higher-temperature core plasma and introduced it to the divertor simulation plasma in the D-module. With the application of ECH, the detached plasma moved to the attached condition. Moreover, with the injection of SMBI into the ECH-injected plasma, the attached plasma moved to a detached condition. This study revealed the effect of sudden changes in the particle flux on detached simulation plasma for the first time.}, year = {2024}, journal = {AIP Advances}, volume = {14}, pages = {125324}, doi = {10.1063/5.0241333}, language = {eng}, }
