MS20-P13 Highest Data Quality with Latest In-House Sources and Detector TechnologyModern chemical and biological crystallography continuously pushes the limits to ever smaller samples with typically weaker diffraction properties. Here we will present a number of structures obtained from extremely challenging samples. Experimental data collected on an in-house system illustrate the strength of two new components which tremendously improve the performance of laboratory instrumentation: the new ImS DIAMOND source and the new PHOTON III X-ray detector.
The air-cooled ImS DIAMOND microfocus sealed tube source uses a unique diamond hybrid anode technology to produce intensities similar to modern microfocus rotating anodes. The anode consists of a diamond substrate coated with copper. The high thermal conductivity, low thermal expansion and extreme hardness of diamond make it an ideal substrate, which allow for higher power loading and greater long-term stability of the source, delivering the brightest micro-focus sealed tube ever.
As of today another problem associated with high-end X-ray sources is gone: high maintenance costs. The ImS DIAMOND does not require any routine maintenance and has the same legendary life time which makes the ImS system the most popular microfocus X-ray source for more than a decade.
The PHOTON III is a new CPAD (charge-integrating pixel array detector), which utilizes a mixed-mode approach for data collection. The weak reflections are measured in photon-counting mode and the strong reflections are measured in integrating mode. Consequently, the ultra-sensitive PHOTON III detector can collect very weak reflections without suffering from charge-sharing or non-linearity effects common to other photon-counting detectors.
Bruker’s D8 QUEST and D8 VENTURE both take advantage of these improvements in source and detector technology, leading to a previously unknown level of performance without increasing operational costs.References:
