• Timing filter amplifiers (fast timing)
• Delay and fast amplifiers (signal synchronization)
• Advanced pulse shaping with Gaussian and triangular filters for improved resolution
• Automatic features such as baseline restoration, noise discrimination, and pile-up rejection
• Compatible with HPGe, scintillation, silicon, and proportional detectors
• Available in single, dual, and multi-channel configurations for flexible system design
• NIM-standard modules for easy integration into laboratory systems

Amplifiers are one of the most critical electronic components in any radiation detection and spectroscopy system, responsible for conditioning detector signals before analysis.

When a detector (such as HPGe, NaI, or silicon) detects radiation, it produces a weak electrical pulse. The amplifier processes this signal by:

Increasing signal amplitude (gain)
Shaping the pulse to improve signal-to-noise ratio
Preparing the signal for accurate analysis by systems such as MCA or SCA

ORTEC offers a comprehensive range of amplifiers designed for different applications:

Spectroscopy Amplifiers (e.g., 570, 671, 672)
→ Optimized for high-resolution energy spectroscopy with advanced shaping and noise reduction
Timing Filter Amplifiers (e.g., 474, 579)
→ Designed for fast timing and coincidence measurements
Fast Amplifiers & Multi-channel Amplifiers (e.g., 855, 9310 series)
→ Support high count-rate applications and multi-detector systems

These amplifiers incorporate advanced features such as automatic pole-zero adjustment, gated baseline restoration, and pulse pile-up rejection, ensuring accurate measurements even at high counting rates.

By optimizing pulse shape and minimizing noise, amplifiers play a key role in achieving high energy resolution, accurate timing, and reliable spectroscopy results.
