Description
We are investigating the use of field emission arrays (FEAs) made of silicon to purify a liquid xenon detector. It is known that electronegative contaminants can be drifted by attaching electrons to them and using an external field. Our main objective is to see if either electrons or holes can be used to drift Rn in LXe, with the ultimate goal being to use this to remove Rn from LXe. We are currently in the stage to look into properties of the FEAs such as current output, total charge and stability. Two tests resulted in current injection.
