The Muon g-2 experiment uses electrostatic quadrupoles for vertical focusing in the muon storage ring. High voltage (HV) feedthroughs provide electrical contact across the vacuum-air interface. Trapped electrons drift in the direction of the cross product between the electric and magnetic fields. These electrons drift along the quadrupole HV leads and eventually damage the HV feedthrough insulators on the vacuum side. Damaging these insulators increases the likelihood of sparking in the Quadrupole System. HV feedthrough extensions are used to position the HV feedthroughs in a low magnetic field region, thereby eliminating the trapped electrons that cause damage. The design and installation of the HV feedthrough extensions are presented in this poster.
