AST- 9731106 Abstract Funds will be used to expand the pulsar system now in Green Bank to provide the full arsenal of data acquisition that has been demonstrated by the Berkeley and CalTech groups. The wider bandwidth incoherent system will improve the sensitivity of high frequency polarimetry by a factor of 2.5, will allow sensitive searches for new pulsars, and provide new capability for single pulse studies. The voltage recording system brings a unique capability to Green Bank for precision timing, searches at very large dispersion measure and very high time resolution studies of individual pulses. A 1-GHz Acousto-Optical Spectrometer will be developed for pulsar studies. This can be used to study diffractive scintillation and real-time steering of other recordings to scintillation maxima.

AST-9731106抽象资金将用于扩展绿色银行的PULSAR系统，以提供伯克利和加州理工学院集团已证明的数据采集的完整库。 更宽的带宽不一致系统将提高高频极化法的灵敏度2.5倍，将允许对新的脉冲星进行敏感的搜索，并为单个脉冲研究提供新的能力。 电压记录系统为绿色银行带来了独特的能力，以实现精确的时机，搜索非常大的分散度量以及对单个脉冲的非常高的时间分辨率研究。 将开发1 GHz声学光谱仪用于PULSAR研究。 这可用于研究其他记录到闪烁最大值的衍射闪烁和实时转向。
