The first detailed assessment of ion/atom cross section data for beam stopping was completed at JET in 1989 ( small corrections and extensions were made to the file up to 1993). This file was originally saved /adas/adf02/ionatom/h.dat but was later reformatted and saved as /adf02/sia#h/sia#h_rfm#h.dat.Guided by experimental observations at JET and the lack of high quality CCAO calculations when the JET 1989 data set was compiled,the cross- sections of the JET 1989 data set was considered to be some what under-estimated.A new review of all ion/atom collision data was carried out. The only substantial contribution found was that of the close coupled atomic orbital (CCAO) calculations of Toshima & Tawara [1].This data together with the data of Janev & Smith [2] was used to create yet another ADF02 type file,sia#h_tosh#h.dat. However, the CCAO calculations of Toshima & Tawara[1] only include states up to n=4 and so some over-estimation is present,particularly for ion impact ionisation from n=3 and n=4 shell.The cross-sections contained in this data set are considered to be over-estimated. A comparative data set was constructed which was a compromise between both data sets,this is what is called the JET 1997 review data set , sia#h_j97#h.dat. The JET 1997 review data is the preferred data set. The working accuracy was obtained by running ADAS310 using each data set.The results from using the JET 1997 review data is taken as the most accurate value.The results from using the JET 1989 data set are used to obtain a lower limit. The results from the Toshima & Tawara data set are used to obtain an upper limit. Using the values of the lower and upper limit a percentage difference is used to describe the MAXIMUM deviation from the results obtained using the JET 1997 review data.
