A century of particle physics discoveries has culminated in the development of the Standard Model, arguably the most successful theory in all of science. However, compelling lines of evidence indicate that the Standard Model is incomplete. Resolving these open questions will transform our understanding of the most basic processes in the universe.

Beyond-Standard-Model physics experiments often need to study rare processes - such experiments may operate for years to measure a handful of signal events. It is therefore imperative to employ a detection technology that extracts as much information as possible, to maximise the scientific value of the signal and to help suppress unwanted backgrounds. To this end, our group is developing micropatterned gaseous time projection chambers (TPCs). TPCs measure the 3D ionisation track created by particle events with exquisite sensitivity and spatial resolution, offering unparalleled event information.

We have built two several-litre prototype TPCs, and are building a scaled-up 54 litre TPC called CYGNET. CYGNET's modular design will form the basis of a future large experiment targeting dark matter and neutrino physics, called CYGNUS-Oz, to be located in the Stawell Undergound Physics Laboratory, in Victoria.

A number of projects are available for students with an interest in this area:

• Directional particle measurements with the prototypes to optimise the technology (gas composition, avalanche gain stage, readout)
• Hardware and software development for the prototypes
• Simulations of particle events, gas physics, and signal formation in the prototypes and future detector designs
• Machine learning methods to improve event reconstruction

Experience with other experimental projects is useful. Students with experience in electronics, signal processing, or software development are encouraged to become involved.
