The role of error fields in stellarators is explored this work through simulations of, and experiments performed on, the Wendelstein 7-X (W7-X) stellarator. Previous experimental results, based on limiter plasmas W7-X, suggest that are small experiment plasmas. In work, we document results from first divertor campaign W7-X with a focus resonant edge island structure. Measurements obtained using thermocouples corroborate earlier correctable, requiring only 5% total rated current trim coil...
The measurement and correction of error fields in Wendelstein 7-X (W7-X) is critical to long pulse high beta operation, as small may cause overloading divertor plates some configurations. Accordingly, part a broad collaborative effort, the detection on W7-X experiment has been performed using trim coil system conjunction with flux surface mapping diagnostic resolution infrared camera. In early commissioning phase experiment, coils were used open an n/m = 1/2 island chain specially designed...
Next generation EUV sources for photolithography use light produced by laser-produced plasmas (LPP) from ablated tin droplets. A major challenge extending the lifetime of these devices is mitigating damage caused deposition debris on sensitive collection mirror. Especially difficult to stop are high energy (up 10 keV) highly charged ions created in plasma. Existing solutions include stopping gas, electric fields, and magnetic fields. One common configuration consists a field perpendicular...
Dusty plasmas are known to support a diverse range of instabilities, including both generalizations standard plasma instabilities and ones caused by effects specific dusty systems. It has been recently demonstrated that novel broad class streaming termed resonant drag (RDIs), can be attributed particular resonance phenomenon, manifested defective eigenvalues the linearized dust/fluid system. In this work, it is phenomenon not unique RDIs used as framework understand wider instabilities....
Helical equilibria can be generated by arrangements of planar coils similar to tokamaks, but without a central solenoid and with the toroidal field (TF) tilted respect vertical. This is known from earlier numerical works, e.g. P.E. Moroz, Phys.Plasmas 2, 4269 (1995). However, such concept tends need large (of low aspect ratio) form small plasmas ratio). Here it numerically shown that larger, more attractive vacuum flux surfaces -- relative size device carefully optimizing inclination TF...
