Team}, title = {Nonlocal transient transport and thermal barriers in Rijnhuizen Tokamak project plasmas}, abstract = {In the Rijnhuizen Tokamak Project plasmas, a transient rise of the core electron temperature is observed when hydrogen pellets are injected tangentially to induce fast cooling of the peripheral region. High-resolution Thomson scattering measurements show that the T-e rise is associated with large temperature gradients in the region 1 < q < 2. This region acts as a layer of transiently increased thermal resistivity (transport barrier) when probed by fast heat pulses from modulated electron cyclotron heating.}, year = {1999}, journal = {Physical Review Letters}, volume = {82}, number = {25}, pages = {5048-5051}, month = {Jun 21}, isbn = {0031-9007}, doi = {10.1103/PhysRevLett.82.5048}, language = {eng}, }
