  1. Some key results from SOL H-mode characterisation Barbora Gulejová, Richard Pitts, Roland Behn, Jan Horáček OUTLINE • * Experiments - motivation • * Comparison of data from old and new shots • * Analysis of data from target langmuir probes Barbora Gulejova

  2. AIM: repetition of #26730 modeled by SOLPS- new data required from : LPs RCPIR 26730-old 31832-new Egde TS laser beam RCP LP + SOLPS LP Barbora Gulejova

  3. Upstream profiles- ne and Teedge TS + RCP + SOLPS Old data #26730 TS New data #3183x TS old TS new Te RCP old RCP new RCP Barbora Gulejova

  4. Te - upstream profile edge TS + RCP + SOLPS New + old exp.data + SOLPS Barbora Gulejova

  5. ne - upstream profile edge TS + RCP + SOLPS TS old TS new TS old Old data #26730 New data #3183x RCP old RCP new RCP old ne RCP data x corr.factor ~ 0.5 -account for increased Aproj of RCP due to ρL(i) Barbora Gulejova

  7. ELM-Time evolution of jsat at outer target # 31832 , V= -100 V => Jsat mode * Jsat [A.cm-2] coavelm from LP=4 ELM * * * * * Post-ELM Pre-ELM * * r-rsep [m] outer target t [s] Barbora Gulejova

  8. Outer target div.leg sweeping #31839 (jsat)vs fix outer div.leg #31832 (jsat) #31839 – target sweep => each probe gives part of jsat profile Jsat [A.cm-2] LP=3 ELM - phase Time  R(probe)-R(strike point) Jsat target profile from envelopes of jsat in certain times (between or during elm) between ELMs t [s] Barbora Gulejova
