Description:

Code and data repository accompanying the publication "A nontwist field line mapping in a tokamak with ergodic magnetic limiter" .

Both data and codes are available in the file "codes.zip".

Requirements

Fortran compiler (gfortran, ifort, ...).
Octave (software or OctaveOnline )
Files available in "codes.zip".

Figure 5

Data were generated by constructing the phase spaces for the Original Martin-Taylor map (Figure 2 a) and calculating the half-width of the largest island. The results are in the files:

Figure 5 (a) - Imax_ILP_m_1.dat
Figure 5 (b) - Imax_ILP_m_2.dat
Figure 5 (c) - Imax_ILP_m_3.dat

Figure 5 (c) - ImaxPend_ILP_m_3.dat
Figure 5 (d) - ImaxPend_ILP_m_4.dat

Figure 6

Data were generated by constructing the phase spaces for the Extended Martin-Taylor map (Figure 2 b) and calculating the half-width of the largest upper and lower island, for m =3. The results are in the files:

Figure 6 (a) - Imax_LowerChain.dat and Imax_UpperChain.dat

The pendulum approximation data are in the files
