  1. SOLPS5 simulations of Type I ELMing H-mode at JET Barbora Gulejová Richard Pitts,David Coster, Xavier Bonnin, Marc Beurskens, Stefan Jachmich, Arne Kallenbach

  2. OUTLINE Type I ELMing H-mode (3MA,3T) at JET SOLPS - experiment benchmark Type I ELMing H-mode (2MA,2T) at JET SOLPS – EDGE2D/Nimbus benchmark * * * *

  3. Type I ELMing H-mode on JET =baseline scenario for QDT=10 burning plasma operation on ITER !!! To avoid divertor damage => maximum ΔWELM (ITER) ~ 1MJ # 70224 Parameters Bt = 3 T Ip = 3 MA ne=6x1019 m-3 P(SOL)= 19 MW No GAS PUFF !! ν*ped ~0.03 -0.08 (expected for ITER!) CoreLIDAR Edge LIDAR Li beam HRTS ECE Dalpha PIN ~ 20 MW PRAD(below Xpoint) PRAD (core) ELM parameters felm ~ 2 Hz ΔWELM ~ 1 MJ Langmuir probes Wdia Bolometry (A.Huber) radiation between ELMs Simulated for the first time ! … with SOLPS5 time

  4. SOLPS vs. experiment - upstream SOLPS grid, sep EFIT, sep CoreLIDAR Edge LIDAR Li beam HRTS ECE ne [m-3] Te [eV] Ti [eV] First results for pre-ELM D[m2.s-1] Χe[m2.s-1] Xi [m2.s-1] * quite promising * unlike for TCV,AU inward pinch radial profile necessary!! D┴= 0.01 m2.s-1 in pedestal 1 m2.s-1 in SOL Χ┴= 0.7 m2.s-1 in pedestal 1 m2.s-1 in SOL Xi < Xe vperp [m.s-1] inward pinch!

  6. Benchmark SOLPS/EDGE2D/Nimbus Succesfully modelled by EDGE2D + NIMBUS by Arne Kallenbach (PPCF 46,2004) # 58569 CoreLIDAR Edge LIDAR Li beam ECE Parameters Bt = 2 T Ip = 2 MA ne= 4x1019 m-3 P(SOL)= 12 MW GAS PUFF from inner divertor !! Dalpha PIN ~ 14 MW PRAD (core) ELM parameters felm ~ 30 Hz ΔWELM ~ 200 kJ Wdia Grid problem  Deep mesh simulations in progress time

Upstream profiles evolution during ELM ne SOLPS5 Te preELM preELM post ELM 1ms post ELM 1ms ELM peak post ELM 3ms post ELM 3ms ELM peak r-rsep [m] r-rsep [m] Transport coefficients D, Ch, were increased: * during 1ms * everywhere poloidaly * in the interval 5cm inside and 0.5 cm outside of separatrix radialy

  12. CONCLUSIONS Type III ELMing H-mode at TCV and Type I ELMing H-mode at JET have been succesfully simulated by SOLPS5 both steady state and transient event Agreement obtained between : code - experiment code - code * * * * * *
