| PSL have recently delivered a new X-Ray camera with 4 x 150mm diameter
tapers cut into quadrants that butt together to form a camera with a nominal
working aperture of 260 mm diameter. This picture shows the front view
with the 270mm diameter Aluminised Mylar window in the centre. The hermetically sealed aluminium chamber is 438mm diameter x 307mm in length. |

Tapers are ground in-house Cutting the corner radius of one of the 150mm diameter taper quadrants. When the four tapers are assembled together, the radii on each central corner of the tapers form a central perforation of 18mm diameter, through which X-Rays pass to the SAX detector. |
| One of the four finished tapers ready for bonding The two faces that butt up against adjacent taper quadrants' faces are clearly visible as is the 9mm radius cut into the corner. |

 |
The 150mm taper has a magnification ratio of 3.8:1 |
| The combined quadrant taper assemblies. Mounted and aligned prior to having phosphor coating applied. Note that the dead area that is lost at the segment joints is less than 1mm wide. |  |
 |
This picture shows the quadrant taper assembly undergoing a trial fit with the chamber casing. The rings surrounding the tapers are the window mounting rings. |
| Rear view of the completed camera showing connections for liquid cooling
and gas purging of the CCD detectors. The hermetically sealed ‘D’
connectors for electronic data are also visible. The central aluminised Mylar exit window can just be seen. The exit interface is furnished with ‘0’ ring seal and mounting holes for the SAXS detector. |
