1. SOL plasma in ITER is dense and hot  thick to gas puff as in C-mod
Role of particle transport and neutral penetration on plasma density for L-mode and H-mode confinement regimes without core fuelling (I)
Modelling of ITER fuelling based on B2-Eirene (ionisation + diffusive transport)
SOL plasma in ITER is dense and hot  thick to gas puff as in C-mod
Gas fuelling/recycling ineffective  fuelling of ITER QDT =10 relies on pellets
modelling and circumstantial experimental evidence indicate that role of transport in determining plasma density is important

2. Role of particle transport and neutral penetration on plasma density for L-mode and H-mode confinement regimes without core fuelling (II)
Experimental plan
Plasma conditions for large span of lion/ln in C-mod (low to high Ip) & confinement regimes (measurements of nedge, T edge and Lya essential) with q95 = 3-4
1. Perform Ohmic or low Padd L-mode density scan to highest density (1-4 shots)
2. Perform density scan in EDA : low Ip at low Padd/PL-H (3 shots)
3. Perform density scan in EDA : high Ip at low Padd/PL-H (3-4 shots)
4. Perform density scan in EDA : high Ip at high Padd/PL-H (3-4 shots)
5. Repeat 3 and 4 in ELMy H-mode (6-8 shots)
