FPGA Messbauer hardware (generator, emulation of signal from gamma-source registered and amplified.

Gamma optics scheme: S* ------> [A, Modulated with Doppler] ------> D-A, where:

  • S* - gamma radiation source
  • A - absorber under modulation
  • D-A - Detector + Amplifier

This project

  • Generates signals for Messbauer Driver Modulator (saw tooth generation)but without peak aliasing (PROPRIETARY algorithm)
  • Generates signals for accumulation: Start and Channel
  • Generate decay signal emulation (means gamma quants that were registered and pass amplification to diff discriminator)

This hardware project is a Spartan6 AX309 Board (ALINX) include following features:

  1. Messbauer saw-tooth generator: Saw tooth gen file

  2. Messbauer generator: Start and Channel signal with adjustable Start duration and Channel number, relation between Start and Channel: Start and Channel relations

  3. Testing signal for differential discriminator: 17 impulses total: 5 must be counted, others not:

Signal for diff discriminator
