The Diagnostic neutral beam (DNB) is used as a beam for active charge exchange recombinationspectroscopy to measure the helium ash density in the core plasma region. The DNB injects H0beam to the plasma. TheIndian Test Facility (INTF) is a facility being constructed at Institute for Plasma Research (IPR), to characterize ITER(International Thermonuclear Experimental Reactor) -DNB beam with full specification. INTF is a vacuum vessel of 180m3 volume and capable of providing Ultra High Vacuum Environment for the beam operation. The DNB beam sourceproduces and accelerates negative ions. It is supported on the vessel mechanically and, for its functionality, is feed withhigh electrical potential of -100kV. For electrical isolation between Beam Source and Vacuum vessel, Post Insulatorshave to be provided to meet the electrical and mechanical requirements. The Post Insulators are mainly composed ofceramic attached with the metallic flanges and then coupled to beam source support structure to provide themmechanical support and electrical isolation.
