We present a survey of \sim 800 square degrees of the galactic plane observed with the QUaD telescope . The primary product of the survey are maps of Stokes I , Q and U parameters at 100 and 150 GHz , with spatial resolution 5 and 3.5 arcminutes respectively . Two regions are covered , spanning approximately 245 - 295 ^ { \circ } and 315 - 5 ^ { \circ } in galactic longitude l , and -4 < b < +4 ^ { \circ } in galactic latitude b . At 0.02 ^ { \circ } square pixel size , the median sensitivity is 74 and 107 kJy/sr at 100 GHz and 150 GHz respectively in I , and 98 and 120 kJy/sr for Q and U . In total intensity , we find an average spectral index of \alpha = 2.35 \pm 0.01 \mathrm { ( stat ) } \pm 0.02 \mathrm { ( sys ) } for |b| \leq 1 ^ { \circ } , indicative of emission components other than thermal dust . A comparison to published dust , synchrotron and free-free models implies an excess of emission in the 100 GHz QUaD band , while better agreement is found at 150 GHz . A smaller excess is observed when comparing QUaD 100 GHz data to WMAP 5-year W band ; in this case the excess is likely due to the wider bandwidth of QUaD . Combining the QUaD and WMAP data , a two-component spectral fit to the inner galactic plane ( |b| \leq 1 ^ { \circ } ) yields mean spectral indices of \alpha _ { s } = -0.32 \pm 0.03 and \alpha _ { d } = 2.84 \pm 0.03 ; the former is interpreted as a combination of the spectral indices of synchrotron , free-free and dust , while the second is attributed largely to the thermal dust continuum . In the same galactic latitude range , the polarization data show a high degree of alignment perpendicular to the expected galactic magnetic field direction , and exhibit mean polarization fraction 1.38 \pm 0.08 \mathrm { ( stat ) } \pm 0.1 \mathrm { ( sys ) } % at 100 GHz and 1.70 \pm 0.06 \mathrm { ( stat ) } \pm 0.1 \mathrm { ( sys ) } % at 150 GHz . We find agreement in polarization fraction between QUaD 100 GHz and WMAP W band , the latter giving 1.1 \pm 0.4 % .
