Cluster Rotation Experiments at Flinders University
For the next 6 weeks, we will be heading to Flinders
University of South Australia in Adelaide to perform experiments on dust
cluster rotation in an axial magnetic field. This will be a great opportunity
for the only two complex plasma laboratory groups in Australia to work
Historically, Flinders University was the first experimental
group which initiated the study of complex plasma in Australia since 1997.
The group was led by Dr. Leon Mitchell, with his two PhD students Nathan
Prior and Felix Cheung. The group had performed experiments in the dynamics
of dust particles such as vortex motion, convection cell, particle oscillation
and cluster rotation. The apparatus used was built by Nathan Prior and
it is a inductively coupled rf plasma system.
Later on in 2000, Prof. Brian James of the University
of Sydney has taken interests in the study of complex plasma. After his
visit to Adelaide, together with Dr. Alex Samarian and his student William
Tsang, the second experimental complex plasma apparatus was built at Sydney.
The apparatus is a capactively coupled rf plasma system.
Inevitably, in the year 2001, after Felix went to the
University of Sydney to continue his PhD degree, the collaboration between
Adelaide and Sydney took place.

One is the University of Sydney and the other one is the Flinders University
of South Australia in Adelaide.

initiated the study of complex plasma in Australia since 1997.
