Electro-Formed Copper Cooling Block for AGIPD @ European XFEL | |
|
||
| The European XFEL will generate ultrashort X-ray flashes with a brilliance a billion times higher than that of the best conventional X-ray radiation sources. The AGIPD (Adaptive Gain Integrating Pixel Detector) is a high speed detector for XFEL. It allows single pulse imaging at 4.5 a MHz frame rate with a dynamic range allowing single photon detection and detection of more than 10,000 12.4 keV photons per pixel in the same image. This development is a collaboration between DESY, the University of Hamburg, the University of Bonn (all in Germany) and the Paul Scherrer Institute (PSI) in Switzerland. Four AGIPD modules are mounted on a cooling block using silicone oil as a coolant. The total heat load is about 200 W per cooling block. The aim is to achieve -20°C sensor temperature with a non-uniformity of less than 5 K on the sensors and to cool electronic components with the return flow. The detector components are operated in vacuum. Following first tests with different materials and production methods, the copper cooling blocks were manufactured by electro-forming. The poster gives information on production details and results on cooling tests done on the final detector assembly. | ||
