xNTD SCIENCE WORKSHOP
ATNF Lecture Theatre, Marsfield Site,
6 April 2005

Overview
As part of the Major National Research Facilities programme, the astronomy
community was given funding for SKA technology demonstrators. One aspect
of this funding is the construction of the New Technology Demonstrator
(NTD), a parabolic dish with a large focal plane array which will yield
a large field of view on the sky. If the NTD proves to be a viable step on
the pathway to the SKA, the next stage is the construction of an array
of telescopes capable of cutting edge science, which we have dubbed
the Extended New Technology Demonstrator or xNTD.
The current specifications for the
xNTD are for 20 dishes, each of 15-m diameter and with
a focal plane array consisting of 100 elements operating over a
frequency range of 800-1700 MHz, yielding a
field-of-view on the sky of about 40 square degrees at 1.4 GHz. The
telescope will be located near Mileura Station in Western Australia,
in one of the most radio-quiet regions on earth.
The telescope will be extremely powerful for large-scale surveys.
The meeting will focus on the science which can be done with the xNTD
and will help to constrain some of the engineering specifications,
such as the frequency range, the bandwidth, the number of frequency
channels and the configuration.
Registration
The meeting will be held in the Lecture Theatre on the Marsfield site
of the ATNF. Morning and afternoon teas and lunch on the 6th will be provided
in the Canteen for all participants.
Anyone wishing to attend should contact Simon Johnston
(Simon.Johnston@csiro.au) so that we know the numbers for catering purposes.
