Welcome to the new homepage for the PDFgetN program. We are now hosting the programs on Source Forge and hope you like the added features, such as mirror download sites all over the world.

PDFgetN is used to process scattering data from time-of-flight neutron (TOF) diffractometers (such as NPDF at the Lujan Neutron Scattering Center) to obtain the normalized structure function, S(Q), and the atomic pair distribution function, G(r).

The program can read data from all TOF neutron powder diffractometers that can create GSAS type files. All processing parameters are stored with the resulting data and can be imported again into the program. The program is controlled via a graphical users interface but can also be used in batch mode. PDFgetN is based on the GLASS package developed at the Intense Pulsed Neutron Source.
