Detachment in helium(He)discharges has been achieved in the EAST superconducting tokamak equipped with an ITER-like tungsten *** paper presents the experimental observations of divertor detachment achieved by increasing the plasma density in He *** density ramp-up,the particle flux shows a clear rollover,while the electron temperature around the outer strike point is decreasing *** divertor detachment also exhibits a significant difference from that observed in comparable deuterium(D)*** density threshold of detachment in the He plasma is higher than that in the D plasma for the same heating power,and increases with the heating ***,detachment assisted with neon(Ne)seeding was also performed in L-and H-mode plasmas,pointing to the direction for reducing the density threshold of detachment in He ***,excessive Ne seeding causes confinement degradation during the divertor detachment *** precise feedback control of impurity seeding will be performed in EAST to improve the compatibility of core plasma performance with divertor detachment for future high heating power operations.

Neon(Ne)seeding is used to cool the edge plasma by radiation to protect the divertor tungsten(W)target in the Experimental Advanced Superconducting Tokamak(EAST).The W sputtering in the outer divertor target with Ne seeding is assessed by the divertor visible spectroscopy *** is observed that the W sputtering flux initially increases with Ne concentration in the divertor despite the decreasing plasma *** reaching a maximum around 25 eV,the W sputtering rate starts to decrease,presenting a suppression *** effect on the divertor W sputtering flux and yield due to the competition between the increase of the Ne concentration and the decrease of the plasma temperature is *** results show that enough Ne seeding is essential to effectively reduce the electron temperature and thus to suppress W ***,ELM suppression is observed when Ne and W impurities enter the core plasma,which could be correlated to the enhanced turbulence transport in the pedestal.
