Raith Field Service and LEO are here and we attempted to qualify the
system. Qualification failed due to field rotation and elliptic beam

Tonight are baking out overnight to improve vacuum.
In testing today we saw elevated vacuum levels as we ramped up towards
20 keV and observed one transient arc event.
Full update tomorrow afternoon.
