#### Abstract:
The TRIUMF CANadian Rare isotope facility with Electron Beam ion source (CANREB) High Resolution Separator (HRS) has been designed to separate rare iso-
topes with mass/charge differences of only one part in 20 000 in beams with transverse
emittances of 3 μm. To reach this high resolution, high-order aberration must be corrected using a multople corrector; from experience we know that tunning such a multipole is in practice very challenging.
The unique geometry of our multipole allowed for the development of a novel tunning method, based on determining the desired pole voltages directly from measured emmitance.
This novel tuning algorithm is presented alongside a web application which has been developed in anticipation of the commissioning of the HRS.
