ABSTRACT.I describe a simple new method for collimating a Cassegrain telescope that gives near-perfect correction over a wide field of view. This method was used to collimate the 6.5 m MMT in 2002 ...

New observations from the National Science Foundation National Radio Astronomy Observatory's (NSF NRAO) Karl G. Jansky Very Large Array (NSF VLA) provide compelling evidence supporting a universal ...

PREVIOUS attempts to measure the annual parallax of intense radio stars 1,2 have indicated that their distances exceed 1/50 parsec. These results were obtained by using an interferometer arrangement ...

July 13, 2009 (Toronto, Canada) — Combining high-sensitivity and high-resolution collimation in single photon emission computed tomography (SPECT) scans produces a contrast improvement in an image, ...

A series of studies of "ideal" beams has been carried out using Monte Carlo simulation with the goal of providing guidance for the design of epithermal beams for boron neutron capture therapy (BNCT).
