Software for Modelling Positron-Beam Depth-Profiling Data

H. Schut , A. van Veen

The fitting program VEPFIT has been extended with applications running under the Microsoft Windows environment facilitating the input and output of the VEPFIT fitting module. We have exploited the Microsoft-WindowsR graphical users interface by making use of dialog windows, scrollbars, command buttons etc. The user communicates with the program simply by clicking and dragging with the mouse pointing device. Keyboard actions are limited to a minimum. Upon changing one or more input parameters the results of the modeling of the S-parameter and Ps-fraction versus positron implantation energy are updated and displayed. This action can be considered as the first step in the fitting procedure upon which the user can decide to further adapt the input parameters or to forward these parameters as initial values to the fitting routine. The modeling step has proven to be helpful for designing positron beam experiments.
