Special Features

  • Stand-alone, computer-controlled pulsed laser-generated ion energy measurement system.
  • Integrated universal synchronization unit: Compatible with any type of PLD laser.
  • Pulsed ion flux detection: Digitizes waveforms of both pulses, incoming and energy-discriminated.
  • Rapid analysis of kinetic energy: In a single laser pulse, determines Emax for element defined by the user.
  • Deposition flux stability analysis: Displays real-time statistical variation of arriving ion pulses.
  • Sweep mode: Allows user control over range and step size of collector bias sweeping.
  • Proprietary data processing algorithm: Allows user control over ion energy distribution N(E) and F(E).
  • 3D representation of ion pulse sweep waveforms.
  • Extensive data file library: Facilitates saving any pulse waveform and energy distribution for future analysis and presentation.
  • Time-of-flight mode: Delivers fast turn-around spectrum in TOF approximation, from a single laser pulse, in real-time.
  • Thermal ion evaluation/analysis: Estimates concentration of low-energy ions relative to energetic ions.
  • Laser pulse detection and stability analysis: Displays real-time pulse-to-pulse variations.


Neocera Ion Energy Spectrometer (IES-200) is an Electrostatic Retarding Fieldtype Spectrometer. Ions of different kinetic energy, arriving at the IES sensor are separated from electrons, discriminated by their energy, and collected by the Spectrometer. The spectrum displayed will provide information on the most important ‘figure-of-merit’ of the PLD deposition process (ie kinetic energy distribution of the ions arriving at the growth substrate).

The spectral distribution function F(E) ≡ dN(E)/dE is the derivative of the measured N(E) where N(E) is the number of ions with energy greater than E. F(E) provides the PLD user quantitative information about the PLD process.
