Abstract: (JACoW)

To test the pumping performance of NEG coated Cu-CrZr absorber, we performed a comparative experiment on the two absorbers, one with NGE coating and the other one without coating. First, we run the Monte Carlo simu-lation by using MolFlow+ code to estimate the pressure inside test chamber at different thermal outgassing rate. And then two absorbers are mounted inside the chamber for the pressure vs. time profiles testing. The experimental set-up and pressure profiles will be presented here.
