Overview of physics studies on ASDEX Upgrade [PDF]
Nuclear Fusion, 2019 Abstract The ASDEX Upgrade (AUG) programme, jointly run with the EUROfusion MST1 task force, continues to significantly enhance the physics base of ITER and DEMO. Here, the full tungsten wall is a key asset for extrapolating to future devices.Meyer, H., Angioni, C., Albert, C.

Nuclear Materials and Energy, 2022 The electric field in the Scrape-Off Layer (SOL) of fusion plasmas is a key quantity affecting the local plasma transport and possibly also the overall plasma confinement.

Nuclear Fusion, 2003 Recent results from the ASDEX Upgrade experimental campaigns 2001 and 2002 are presented. An improved understanding of energy and particle transport emerges in terms of a critical gradient model for the temperature gradients. Coupling this to particle diffusion explains most of the observed behaviour of the density profiles, in particular, the ...Zohm, H., Angioni, C., Arslanbekov, R., Atanasiu, C., Becker, G., Becker, W., Behler, K., Behringer, K., Bergmann, A., Bilato, R., Bobkov, V., Bolshukhin, D., Bolzonella, T., Borrass, K., Brambilla, M., Braun, F., Buhler, A., Carlson, A., Conway, G.D., Coster, D.P., Drube, R., Dux, R., Egorov, S., Eich, T., Engelhardt, K., Fahrbach, H.U., Fantz, U., Faugel, H., Finken, K.H., Foley, M., Franzen, P., Fuchs, J.C., Gafert, J., Fournier, K.B., Gantenbein, G., Gehre, O., Geier, A., Gernhardt, J., Goodman, T., Gruber, O., Gude, A., Gunter, S., Haas, G., Hartmann, D., Heger, B., Heinemann, B., Herrmann, A., Hobirk, J., Hofmeister, F., Hohenocker, H., Horton, L.D., Igochine, V., Jacchia, A., Jakobi, M., Jenko, F., Kallenbach, A., Kardaun, O., Kaufmann, M., Keller, A., Kendl, A., Kim, J.W., Kirov, K., Kochergov, R., Kollotzek, H., Kraus, W., Krieger, K., Kurki-Suonio, T., Kurzan, B., Lang, P.T., Lasnier, C., Lauber, P., Laux, M., Leonard, A.W., Leuterer, F., Lohs, A., Lorenz, A., Lorenzini, R., Maggi, C., Maier, H., Mank, K., Manso, M.E., Mantica, P., Maraschek, M., Martines, E., Mast, K.F., McCarthy, P., Meisel, D., Meister, H., Meo, F., Merkel, P., Merkel, R., Merkl, D., Mertens, V., Monaco, F., Muck, A., Muller, H.W., Munich, M., Murmann, H., Na, Y.S., Neu, G., Neu, R., Neuhauser, J., Nguyen, F., Nishijima, D., Nishimura, Y., Noterdaeme, J.M., Nunes, I., Pautasso, G., Peeters, A.G., Pereverzev, G., Pinches, S.D., Poli, E., Proschek, M., Pugno, R., Quigley, E., Raupp, G., Reich, M., Ribeiro, T., Riedl, R., Rohde, V., Roth, J., Ryter, F., Saarelma, S., Sandmann, W., Savtchkov, A., Sauter, O., Schade, S., Schilling, H.B., Schneider, W., Schramm, G., Schwarz, E., Schweinzer, J., Schweizer, S., Scott, B.D., Seidel, U., Serra, F., Sesnic, S., Sihler, C., Silva, A., Sips, A.C.C., Speth, E., Stabler, A., Steuer, K.H., Stober, J., Streibl, B., Strumberger, E., Suttrop, W., Tabasso, A., Tanga, A., Tardini, G., Tichmann, C., Treutterer, W., Troppmann, M., Urano, H., Varela, P., Vollmer, O., Wagner, D., Wenzel, U., Wesner, F., Westerhof, E., Wolf, R., Wolfrum, E., Wursching, E., Yoon, S.W., Yu, Q., Zasche, D., Zehetbauer, T., Zehrfeld, H.P. +167 moreopenaire +8 more sourcesAnalysis and expansion of the quasi-continuous exhaust (QCE) regime in ASDEX Upgrade

Nuclear Materials and Energy, 2019 Previous simulation results for the tokamak ASDEX Upgrade have shown that Magnetic Perturbation (MP) fields could lead to a decrease of the peak heat flux onto the divertor targets. However, experimentally, such a decrease has not been observed.D. Brida, T. Lunt, M. Faitsch, M. Wischmeier, Y. Feng, W. Suttrop, U. Stroth, T.

Fusion Engineering and Design, 2007 Abstract ASDEX Upgrade's recently commissioned discharge control system (DCS) marks the transition from a traditional programmed system to a highly flexible “data driven” one. The allocation of application processes (APs) to controllers, the interconnection of APs through uniquely named signals, and AP control parameter values are all defined as data,Neu, G., Engelhardt, K., Raupp, G., Treutterer, W., Zasche, D., Zehetbauer, T. +5 moreopenaire +2 more sources
