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 摘要 资金将用于扩展目前位于 Green Bank 的脉冲星系统，以提供伯克利和加州理工学院团队已演示的完整数据采集库。 更宽带宽的非相干系统将使高频极化测量的灵敏度提高2.5倍，允许灵敏地搜索新的脉冲星，并为单脉冲研究提供新的能力。 电压记录系统为 Green Bank 带来了独特的精确定时、搜索非常大的色散测量以及单个脉冲的非常高时间分辨率研究的能力。 将开发用于脉冲星研究的 1 GHz 声光光谱仪。 这可用于研究衍射闪烁和其他记录的实时转向至闪烁最大值。
