21cm Cylindrical Radio Telescope Design and Simulation
David McGinnis
Fermilab
Intensity mapping of the 21cm line can be a powerful technique for
constraining dark energy parameters. A three dimensional 21cm intensity map
will require a radio telescope with large collecting area, good resolution,
and quick survey speed. An array of cylindrical reflectors that use fast
Fourier transform beam forming is an excellent candidate for such an
instrument. This talk will describe a cylindrical radio telescope design
methodology and optimization strategy. In addition, a number of possible
designs will be discussed. A full telescope simulation that includes the
effects of noise, calibration errors, and foreground subtraction will
be presented.
