View source for HV insulator for 500 kV

== HV insulator for 500 kV: ==
Work scope summary:
The purpose of this work is to demonstrate an inverted insulator + high voltage cable assembly that can be used to reliably apply 500 kV bias voltage to the a test electrode, with no high voltage breakdown inside or outside the vacuum chamber, such that the developed system can be implemented in a future photogun capable of delivering spin polarized beam from GaAs photocathodes at 350 kV without measurable field emission. This photogun design could then be used for generating a beam of spin-polarized electrons to drive a spin-polarized positron source for high energy nuclear physics experiments like the Continuous Electron Beam Accelerator Facility at JLab, the proposed Electron Ion Collider at BNL, and for positron annihilation studies.
