The TLA technique is an effective and precise on-line remote monitoring methods of wear, corrosion and erosion processes of critical parts in machines under real operating conditions.

This work provides help on planning TLA investigations by giving examples for activity depth profiles calculated by using evaluated cross section data for 86 selected charged particle induced nuclear reactions on 35 elements. 

A calculation tool, TLA2017, was developed to help planning irradiations for TLA applications and determining wear of friction surfaces from measured activity differences. The TLA2017.xls is created in Excel and can be used in MS Excel XP or higher versions. It can be downloaded in compressed form here  (TLA2017.rar, 4.2 MB). Description and quick user help is available in TLA2017-manual.pdf.
