摘要：
We have designed a sounding rocket payload to perform high resolution far ultraviolet (FUV) spectroscopy. The payload will contain a modified Rowland spectrograph, achieving resolution (lambda/delta lambda) of 60,000 by adding a magnifying secondary optic. We will use this instrument to observe two stars on opposing sides of the Local Bubble wall. Obtaining spectra of the O VI doublet in absorption towards these stars will provide new insight into the processes governing hot gas near the cavity wall.
