Xspress 3X/M

With over 100 installations worldwide, the Xspress 3 family of readouts has revolutionised the analysis of fluorescence detector data. Orders of magnitude improvement in throughput, combined with resolution optimisation, helps scientists to conduct faster experiments with better results. Whether your detector is old or new, get the most out of it with the superlative performance of Xspress 3.

We now offer two versions of this revolutionary readout: the recently updated Xspress 3X and its diminutive sibling, the Xspress 3 Mini. Xspress 3X combines the channel capacity of the original Xspress 3 with the flexibility of variable gain inputs, to give you an easily calibrated, multi-channel system. Xspress 3 Mini utilises the same technology, housed in a smaller frame, to bring the benefits to low channel systems at a competitive price.

Software

The following video is an introduction to the basic features of Xspress 3 operated using the EDM interface for EPICS. MEDM screens are also available, but they are similar enough that the following video also applies to them. The primary EPICS components were developed by Diamond Light Source with help from the APS.

Open source software for mapping is available from contributing scientists, please get in touch for details.

The TANGO implementation of the drivers is based on the same C API as the EPICS interface. It has been built to specifications designed collaboratively with the ESRF and Daresbury Lab.

Xspress3 can also be operated through a web based graphical user interface (GUI).
