e2v scientific instruments specialises in purpose-built multi-element Si(Li) detectors for synchrotron or particle accelerator research laboratories where they are used for applications such as XRF, TXRF, EXAFS, XANES and PIXE.

Each detector is designed specially for the application, giving careful consideration to tube size, crystal orientation, windows, vacuum interfaces and shielding.
