Does the job well.
Application Area: Gamma spectrometry
"Good stable spectrometry amplifier, holds calibration well and is very stable with time. Integrates well with older NIMs modules"
The Model 2026 amplifier provides the features and performance of a research amplifier in an easy to use single width NIM module. Now you can have the flexibility you need without the amplifier set-up and adjustment aggravation you don’t need.
The Model 2026 unit lets you select either Gaussian or Triangular pulse shaping for the Unipolar output with a convenient front panel switch. In addition, it offers a choice of six front panel switch-selectable shaping time constants for each of the pulse shaping methods. This direct control of both the shaping method and time constants lets you select the configuration that will optimize resolution and throughput performance based on your application.
The 2026 unit’s Pileup Rejector/Live Time Corrector (PUR/ LTC) circuitry allows quantitative gamma analysis with minimal dependence on system count rate. The PUR circuit interrogates incoming pulses for pile up and generates a signal that prevents the ADC from converting the piled up events. The LTC circuit then generates a system dead time that extends the collection time to compensate for the events lost due to pileup rejection. The result: lower background, better resolution and accurate live time information for the best possible analysis results.
But don’t worry about setting up this amplifier. Many of the 2026 unit’s features are self-adjusting so you get the performance you need and a trouble-free setup. The 2026 amplifier automatically adjusts the PUR threshold just above your system noise level, insuring PUR efficiency and minimizing the spectral distortion caused by pile up at high count rates. The restoration rate and threshold of the gated baseline restorer are also automatically optimized for both low and high count rate applications. With all these automatic features the 2026 unit gives you consistently better data for your activity calculations, regardless of the count rate, the application or the operator.
The 2026 amplifier lets you position peaks precisely and easily with its Super Fine Gain (SFG) control. The SFG provides gain resolution better than 1 in 16 000 (0.00625%), allowing greater precision for more accurate peak location in less time. This feature is now a requirement, instead of a luxury, for most spectroscopy systems. This is especially true in applications using detector arrays in which the inputs from several detectors must be combined into a single spectrum.
The excellent overload recovery characteristics of the 2026 unit make it ideal for use with today’s high throughput reset preamplifiers such as the Canberra™ 2101 Transistor Reset Preamplifier. This allows you to assemble a high resolution spectroscopy system without the energy rate limitations normally associated with RC preamplifiers.
