The Methanol Multibeam Survey
A new 7-beam methanol multibeam receiver is being used to survey the Galaxy for newly forming massive stars, that are pinpointed by strong methanol maser emission at 6.668 GHz. The receiver, jointly constructed by Jodrell Bank Observatory (JBO) and the Australia Telescope National Facility (ATNF), was successfully commissioned at Parkes in January 2006. The Parkes-Jodrell survey of the Milky Wa...
متن کاملThe Parkes Multibeam Pulsar Survey
The Parkes multibeam pulsar survey is a high-frequency, fast-sampled survey of the Galactic Plane, expected to discover at least 500 new pulsars. To date, over 200 pulsars have been found, including several young pulsars and at least one with a very high magnetic field. Seven of the new stars are in binary systems; this number includes one probable double-neutron-star system, and one pulsar wit...
متن کاملTiming the Parkes Multibeam Pulsars
Measurement of accurate positions, pulse periods and period derivatives is an essential follow-up to any pulsar survey. The procedures being used to obtain timing parameters for the pulsars discovered in the Parkes multibeam pulsar survey are described. Completed solutions have been obtained so far for about 80 pulsars. They show that the survey is preferentially finding pulsars with higher tha...
متن کاملProtocols for calibrating multibeam sonar.
Development of protocols for calibrating multibeam sonar by means of the standard-target method is documented. Particular systems used in the development work included three that provide the water-column signals, namely the SIMRAD SM2000/90- and 200-kHz sonars and RESON SeaBat 8101 sonar, with operating frequency of 240 kHz. Two facilities were instrumented specifically for the work: a sea well...
متن کاملMultibeam scanning electron microscope: Experimental results
The authors present the first results obtained with their multibeam scanning electron microscope. For the first time, they were able to image 196 array of 14 14 focused beams of a multielectron beam source on a specimen using single beam scanning electron microscope SEM optics. The system consists of an FEI Novanano 200 SEM optics column equipped with a multielectron beam source module. The sou...
