Paper 1 (pdf)
... Here, I outline a new polarimeter design that can take advantage of broad-band X-ray optics by dispersing the incoming X-rays onto a multilayer-coated secondary. The graze angles off of the secondary are large, of order 30-40◦ , and the polarization is determined in aggregate by measuring intensity ...

XMM-Newton
The XMM-Newton, also known as the X-ray Multi-Mirror Mission and the High Throughput X-ray Spectroscopy Mission, is an orbiting X-ray observatory launched by ESA in December 1999 on an Ariane 5 rocket. It is named in honor of Sir Isaac Newton. The telescope was placed in a very eccentric 48 hour elliptical orbit at 40°; at its apogee it is nearly 114,000 kilometres (71,000 mi) from Earth, while the perigee is only 7,000 kilometres (4,300 mi).
