DANTE - The Digital Pulse Processor for X-Ray Spectroscopy

DANTE is a versatile digital acquisition system specifically designed for X-ray spectroscopy application.

Main characteristics

  • Availability: 1CH, 8CH and custom solutions upon requests
  • Pulse filtering: fixed trapezoidal
  • Low-energies: detection down to Beryllium (108eV) and Lithium (54eV)
  • Modular solution: easily extendable up to 32 channels by daisy chain
  • Special functionalities: Waveform scanner, Single Spectrum Mode, Mapping Mode, List Mode, Trigger/Gating mode combined list-waveform
  • System integration: SW libraries available for Windows & Linux. TANGO, EPICS, Python and LabView drivers available

Applications

  • X-ray fluorescence (XRF)
  • Low-energy micro-fluorescence X-ray spectroscopy (µ-XRF)
  • X-ray absorption spectroscopy (XAS, XANES, EXAFS)
  • Ultra-Fast XRF elemental mapping
  • Multi-detector and/or multi-particle coincidence analysis
