| Impact of impurities on turbulent transport || García Regaña, José Manuel || CIEMAT || J. M. García-Regaña (CIEMAT), A. Alonso, A. Baciero, I. Calvo, D. Carralero, T. Estrada, A. González-Jerez, B. López-Miranda, K. McCarthy, D. Tafalla, H. Thienpondt … || Deliberate injection of impurities has been used to access high ion temperature (Ti) scenarios with los turbulence in LHD and to increase transiently Ti in W7-X. Moreover, gyrokinetic simulations have confirmed that impurities can reduce or enhance turbulent fluctuations and heat fluxes, depending on the sign of the impurity density gradient. The present proposal aims at characterizing the role that impurities have on turbulent transport and, consequently, on the performance of TJ-II. | | Impact of impurities on turbulent transport || García Regaña, José Manuel || CIEMAT || J.

| Measurements of electron adiabaticity and comparisons with gyrokinetic simulations || Yanna, Kaitlyn || MIT || Arturo Alonso (CIEMAT) and others || The proposals aims at quantifying the phase difference between electron density and electrostatic potential fluctuations and the two-point Gamma-ExB flux in plasmas with varying values of local density gradient. This proposal's objective is to compare the HIBP measurements of the above-mentioned quantities with the gyrokinetic simulations by Thienpondt et al. | |||
