DESCRIPTION:Upcoming CMB experiments face a major challenge in the search 
 for\nB-mode polarisation\, due to both its weak signal and the potential\n
 for Galactic foregrounds to contaminate observations. B-modes can\nonly be
  generated by tensor modes\, thus their detection would provide\nevidence 
 for Primordial Gravitational Waves.\n\nI will describe Spider\, an experim
 ent that will map a large fraction of\nthe sky with degree-scale resolutio
 n. I will outline an algorithm we\nhave developed for massively multi-dete
 ctor\, polarised map-making.\nI will also present a three-dimensional mode
 l of the Galactic magnetic\nfield and dust density\, which is used to gene
 rate full-sky foreground\ntemplates of Galactic foreground emission.
