  The Multi-mode Acoustic Gravitational wave Experiment (MAGE) is a high
frequency gravitational wave detection experiment. In its first stage, the
experiment features two near-identical quartz bulk acoustic wave resonators
that act as strain antennas with spectral sensitivity as low as $6.6\times
10^{-21} \left[\textrm{strain}\right]/\sqrt{\textrm{Hz}}$ in multiple narrow
bands across MHz frequencies. MAGE is the successor to the initial path-finding
experiments; GEN 1 and GEN 2. These precursor runs demonstrated the successful
use of the technology, employing a single quartz gravitational wave detector
that found significantly strong and rare transient features. As the next step
to this initial experiment, MAGE will employ further systematic rejection
strategies by adding an additional quartz detector such that localised strains
incident on just a single detector can be identified. The primary goals of MAGE
will be to target signatures arising from objects and/or particles beyond that
of the standard model, as well as identifying the source of the rare events
seen in the predecessor experiment. The experimental set-up, current status and
future directions for MAGE are discussed. Calibration procedures of the
detector and signal amplification chain are presented. The sensitivity of MAGE
to gravitational waves is estimated from knowledge of the quartz resonators.
Finally, MAGE is assembled and tested in order to determine the thermal state
of its new components.
