Dimensionless scalings of confinement, heat transport and pedestal stability in JET-ILW and comparison with JET-C

Popis výsledku v původním jazyce

Three dimensionless scans in the normalized Larmor radius .rho.*, normalized collisionality ν* and normalized plasma pressure .beta. have been performed in JET with the ITER-like wall (JET-ILW).The normalized energy confinement and the thermal diffusivity exhibit a scaling with .rho.* consistent with the earlier results obtained in the carbon wall JET (JET-C) and with a gyro-Bohm scaling. In the pedestal, experimental results show that the stability is not dependent on .rho.*, qualitatively in agreement with the peeling–ballooning (P–B) model.The ν* dimensionless scaling shows that JET-ILW normalized confinement has a stronger dependence on collisionality than JET-C.The .beta. dimensionless scan shows that, at low collisionality, JET-ILW normalized confinement has no clear dependence with .beta., in agreement with part of the earlier scalings. At high collisionality, a reduction of the normalized confinement with increasing .beta. is observed
