"Electrons in Cryogenic Liquids: Science and Applications"

Abstract

We are studying a number of aspects in the Cryogenic Liquids:
helium, hydrogen, neon, argon, krypton and xenon.  Each of these has unique
properties that are interesting from the point of view of physics and
applications for tracking and other applications.  We are exploring electron
avalanches in the liquids, and in the first three liquids mentioned, where
the electron is localized in a cavity in the liquid that we call an eBubble,
we are investigating the yield and different detection schemes.  We are also
searching for bubbles containing multiple electrons, interesting for their
unique quantum states.
