Abstract

Prediction of the contamination deposits from the Total Mass Loss (TML) via a novel technique is presented. This predictive methodology, based on the multi-step dynamic outgassing test complemented with a thermogravimetric analysis (TGA), allows assigning outgassed species according to their sticking coefficients to a collector's surface. The proposed approach enables to identify major chemical species outgassed from the tested material and calculate sticking coefficients in a broad temperature range (-175 to+80°C). The preliminary results show that this method could be used as an improved procedure for predictions of deposition and reemission levels.
