  A new high field spectrometer has been built to extend the capabilities of
the $\beta$-detected nuclear magnetic resonance ($\beta$-NMR) facility at
TRIUMF. This new beamline extension allows $\beta$-NMR spectroscopy to be
performed with fields up to 200 mT parallel to a sample's surface
(perpendicular to the ion beam), allowing depth-resolved studies of local
electromagnetic fields with spin polarized probes at a much higher applied
magnetic field than previously available in this configuration. The primary
motivation and application is to allow studies of superconducting radio
frequency (SRF) materials, close to the critical fields of Nb metal, which is
extensively used to fabricate SRF cavities. The details of the design
considerations and implementation of the ultra-high vacuum (UHV) system, ion
optics, beam diagnostics are presented here. Commissioning of the beamline and
spectrometer with radioactive ions are also reported here. Future capabilities
and applications in other areas are also described.
