	The ARIEL electron linac produced its first high-energy beam on 31 September 2014. Despite over 40 years of experience with ion beams, transporting electrons constituted a new challenge for TRIUMF. With good reason: the difference in rest mass makes electrons orders of magnitude more sensitive than ions to magnetic fields (for the same kinetic energy). In this paper we show how beam steering could have been seriously compromised by the remament field from the structural steel of the building, and how this issue was addressed using a technique developed to demagnetize steel-hull ships: we degaussed the entire accelerator vault.
