In this menu you select the model for T_{i}. The neutron emission and K are read in this menu.
\* Options are: 1) Model for chi_i profile ............ <chi_i = chi_e> Unsmoothed chi_e 2) Feedback off, chi_i multiplier is .. <2.00> 3) Neutron emission (DD) ............. <1.287E+16 +/- 8.2%> .. NE-SS-CW 4) Impurity Ti model ................. <Ti set equal for all ions> 5) Species of measured Ti ............ <z=1.000,a=1.000> 6) Convective multiplier ............. <0.000E+00> 7) Fixed tauei ....................... <0.000E+00> 8) Z-exponent on tauei ............... <0.000E+00> 9) Kalpha Ti (keV) ................... <0.000E+00 +/- 0.0%> .. ZERO 10) Species of Kalpha TI .............. <Ni> 11) Passive cx Ti (keV) ............... <0.000E+00> 12) Limits for passive cx fit (keV) ... <3.5,14.> 13) Eta-i 14) FX: Fixed Neutron Sources 15) Edge Ti value (Te or Ti) .......... <Te_edge> 16) CHers cross-section energy dependence model: <0=Off> <1=I;> Ti model option? <n>:
There are three fundamentally different modes for dealing with the ion temperature profile, T_{i}(r), in SNAP:
<1=I;> Ti model option? <n>: MO <2> chi_i model to use? <M>: RETURN \* Options are: 1) Rutherford-Julich 2) Hinton-Hazeltine 3) Bolton-Ware 4) Chang-Hinton (z=1) 5) Chang-Hinton (z>1) 6) chi_i = chi_e 7) Measured Ti profile 8) Profile of Chii <2> chi_i model to use? <M>:The T_{i}(r) profile is the only one in SNAP that can be treated either in analysis or predictive mode. Both electron particle transport and electron heat transport are available in analysis mode only, i.e., SNAP must be provided with measured profiles for n_{e}(R) and T_{e}(R), and it simply infers local transport coefficients.
