Revaporization device inside a glove box and shielded with 50mm thick lead bricks.
It consists of a furnace, a diluter and a filter stage. The tube is made of stainless steel 375 mm lenght and 21.5 mm diameter.
Gamma-ray spectra, chemical composition, morphology and size distribution of captured aerosol, temperature range 200-1000°C
Different samples prepared at different atmosphere (air, hydrogen, air and hydrogen, steam and hydrogen) and different locations, different heating profile (2 K/min - 10 K/min), different process gas feeding rates
