ADAS303 Effective charge exchange spectroscopy emission data graph and fit coefficient The program interrogates charge exchange spectroscopy effective emission coefficient data sets of type ADF12 associated with a particular neutral donor The ADF12 data set collections are for the relevant hydrogen like n n spectrum lines grouped according to the recombining ion The code and data organisation allows the emission coefficient to be obtained by interpolation using cubic splines at plasma conditions and at relative collision energies of choice A minimax polynomial approximation can also be made to the interpolated data The interpolated data are displayed and a tabulation prepared The tabular and graphical output may be printed and include the polynomial approximation Background theory Data from files of type ADF12 contain charge exchange effective emission coefficients for principal quantum shell transitions of hydrogen like impurity ions ge at a reference beam plasma condition of beam energy E 2 plasma ion density N 7D plasma ion temperature T e plasma z effective zeff C and eff n gt n magnetic field strength 9 Also they contain the at varying plasma conditions obtained by keeping all the parameters except one at the reference eff non Sets at the conditions These are called one dimensional scans and there are g following parameter sets Eii 1 1 RN S zeff P BOP with ESD e E i l Ip
