Abstract: Serpens X-1 is a bursting low-mass X-ray binary which has shown Fe K line emission in EXOSAT and ASCA observations. The feature had about 60 eV equivalent width and was centered at 6.5-6.6 keV. This suggested that the inner disk region is sometimes the dominant formation region for these relatively luminous persistent sources with low inclination angles. We will present the results of simultaneous RXTE and Chandra HETGS observations of Serpens X-1, obtained June 2000. We observed one burst simultaneously with both RXTE and Chandra, and one burst with Chandra alone. Potential Fe K line(s) were observed in the average HETGS spectrum in the 6.4-6.7 keV range, but they were weak and/or broad (eq. width < 15 eV). Any low energy lines (near 1.12~keV) are also very weak.
