“…an effective Z eff ≤ 2 with an Ar seeding ≤5%. The use of the EDGE2D-EIRENE code [22,23] has allowed to introduce the real geometry of the FW and of the divertor and to study the topological effects [9]. Just to isolate the different aspects of the problem we have started the analysis on the reference scenario and without including any impurity at all.…”

“…Since the dimensionless scaling above quoted is valid under the assumption of similar plasma shaping, the most advanced technology and methodology has been used in the studies performed to guarantee the necessary equilibrium configurations flexibility and the vertical stability control [7,8]. The edge behavior has been analyzed in greater detail by using the EDGE2D-EIRENE code, for studying the main features of the FAST Scrape-Off Layer (SOL) [9]. Simulations suggest that detachment might be attained at the highest density, even without impurity seeding and thus at relatively low radiation losses, while an increase in the SOL and bulk radiation is needed for the intermediate density regimes.…”

The new magnetic configurations for tokamak divertors, snowflake and super-X, proposed to mitigate the problem of the power exhaust in reactors have clearly evidenced the need for an accurate and reliable modeling of the physics governing the interaction with the plates. The initial effort undertaken jointly by ENEA and IPPLM has been focused to exploit a simple and versatile modeling tool, namely the 2D TECXY code, to obtain preliminary comparison between the conventional and snowflake configurations for the proposed new device FAST that should realize an edge plasma with properties quite close to those of a reactor. The very interesting features found for the snowflake, namely a power load mitigation much larger than expected directly from the change of the magnetic topology, has further pushed us to check these results with the more sophisticated computational tool EDGE2D coupled with the neutral code module EIRENE. After a preparatory work that has been carried out in order to adapt this code combination to deal with non-conventional, single null equilibria and in particular with second order nulls in the poloidal field generated in the snowflake configuration, in this paper we describe the first activity to compare these codes and discuss the first results obtained for FAST. The outcome of these EDGE2D runs is in qualitative agreement with those of TECXY, confirming the potential benefit obtainable from a snowflake configuration.
