1. We want discharges in He in order to study the impurity confinement as a function of effective mass. | 1. We want discharges in He in order to study the impurity confinement as a function of effective mass. | ||
2. We need discharges with solely ECRH and good control with constant density along discharges. Lower densities appear to give more stable target plasmas; however, we wish plasma electron densities that are sufficiently high to ensure good Thomson scattering profiling of the target plasma. | 2.
