Fast Change in Core Transport after L-H Transition
No full textThe transport in the core tokamak plasma is known to change very rapidly after the L-H transition in the edge plasma. A qualitative discussion is given for this fast transmission of the transport change. A picture based on the successive bifurcations is presented.research repor

Probability of Statistical L-H Transition in Tokamaks
No full text"A statistical model of bifurcation of radial electric field E_r is analyzed in relation with L-H transitions of tokamaks. A noise from micro fluctuations leads to random noise for E_r. The transition of E_r occurs in a probabilistic manner. Probability density function and ensemble average of E_r are obtained, when hysteresis of E_r exists. Forward- and backward-transition probabilities are calculated. The phase boundary is shown. Due to the suppression of turbulence by E_r shear, the boundary deviates from the Maxwell's construction rule."research repor
New Features of L-H Transition in Limiter H-Modes of JIPP T-IIU
No full text"In limiter H-modes of JIPP T-IIU, a new type of L-H transition preceded by an ELM is observed. The preceding ELM ( pre-ELM ) appears just prior to the L-H transition. This type of transition is usually observed in H-modes of JIPP T-IIU. The L-H transition without the pre-ELM is triggered only in the case when a sufficiently large rapid current ramp down is emploied. In H-modes with constant q(a)~3.5-4.5, coherent magnetic oscillations with m=3 /n=1 destabilized during L-phase are further enhanced at the pre-ELM, and suppressed suddenly at the transition. This mode is situated in the region of the transport barrier. Propagation frequency of the m=3/n=1 mode, which may be affected by plasma mass rotation, rises appreciably ( by ~ 10 % ) during H-phase with frequent ELMs, but remains unchanged for at least 200 mu s after the transition. Behaviours of the m=3/n=1 and m=2/n=1 modes are well explained by quasi-linear resistive tearing mode analysis for modelled toroidal current density profiles slightly detached from the limiter. These experimental results suggest that the transition is controlled by the change of a magnetic field structure relating to the modification of a toroidal current density profile near the edge. The possibility for the development of edge radial electric field as a consequence of the transition is discussed."research repor
