The purpose of this file repository is to share information about our Ba-tagging in Xe gas efforts at Stanford with people outside our collaboration. The general concept of our setup is in short described in the EMIS2012 conference proceedings (arxiv:1302.6940v1 / Nuclear Instruments and Methods B 317(2013)473).
A report on the most recent measurements is summarized in this document. Please note that this file is identical with the one compiled on May 8, 2014, except this version has contact information added to the document. This document mainly describes recent gas operations and ion extraction from 10 bar Xe and Ar. The measurements presented in chapter 4 were recorded with Ar gas at up to 7.8 bar. At these pressures, ions could successfully be extracted from the gas into a vacuum environment. Some of these measurements are also summarized in a presentation we put together for a workshop on possible ways to implement m/q selection in our setup.
