Enhancing Measurements at the Extremes of Science

At the extremes of science, research often goes beyond “scientific discovery” to become the discovery of new sciences. As you seek to expand the world’s knowledge about phenomena at galactic or nanometer scales—or somewhere in between—confidence in results is strengthened by dependable measurement solutions that provide exceptional speed and data fidelity.

In laboratories around the world, Keysight Technologies instrumentation has become an integral part of advanced experimental systems. Our digitizers are used in two major areas that require high-speed measurements: real-time applications and single-shot or event-based applications. We provide the extreme speed and precision needed for system monitoring and control, and for capturing data from the interactions and events in the experiments themselves.

Addressing your most challenging research

Keysight’s measurement solutions for advanced research can integrate directly into your experiment. Our range of instruments includes oscilloscopes, power supplies and high-speed data converters. Keysight digitizers offer distinct advantages when you need a large number of synchronized acquisition channels: high speed, low-power operation, high channel density and excellent accuracy.

The remainder of this brochure presents six cutting-edge applications in two categories: real-time applications and single-shot measurements.

These range from monitoring and control of the world’s most powerful synchrotron to measurements of rare gamma-ray events in the atmosphere. This is just a small sample of what’s possible with Keysight digitizers. We’ve worked closely with research teams around the world—and we’re ready to help you create the right solution for your most challenging projects.

Setting the Pace in Real-Time Monitoring and Control Dynamic real-time measurements can enable and enhance a variety of experimental processes. Examples include setting system parameters, monitoring high-speed processes until ideal conditions are reached, and recording experimental data for seconds, minutes or hours. In such situations, high-speed data acquisition requires maximum throughput.

Keysight high-speed digitizers implement innovative techniques that maximize data bandwidth and ensure rapid measurements. Today, these capabilities are providing superior throughput in applications such as the control and monitoring of particle and electron beams, and in real-time processing for microwave spectrometry.

Controlling particle beams

The Large Hadron Collider (LHC) at CERN is the world’s most powerful particle accelerator, capable of producing 7 TeV. The CERN Control Centre (CCC) manages the LHC and the chain of accelerators that feed it. Along the injector chain, the Open Analogue Signal Information System (OASIS) can acquire and display more than 2,000 individual analog signals.

With proton bunches traveling near the speed of light, measurement speed is critical and digitizers must have very short dead time between measurements. This is one of the key reasons CERN is using Keysight high-speed digitizers in all of its accelerators.

More than 70 are currently installed, ranging from 500 MS/s to 8 GS/s with 8- or 10-bit resolution on one, two or four channels. They are being used to perform wideband beam monitoring and to monitor forward and reverse RF signals in the accelerator cavities.

Generating high-intensity light

Synchrotron light sources accelerate electrons to produce photon beams that are more than one million times brighter than the sun. This intense light is used for imaging experiments in materials science, biology and medicine down to sub-nanometer scales.

To create a high-quality beam, the Australian Synchrotron (AS) uses a technique called fill-pattern monitoring (FPM) to measure real-time intensity distribution of electron bunches in the storage ring. Its approach to FPM uses an ultra-fast optical diode and a high-performance digitizer to detect and measure optical synchrotron radiation.

Working with Keysight, the AS team developed a diode/digitizer detector that provides bunch-by-bunch resolution. This enables computercontrolled injection of additional electrons into the storage ring to compensate for losses, or to create custom fill patterns for specific experiments. The Keysight-based approach is now an integral part of the control system software at the Australian Synchrotron.

Performing real-time FFT spectrometry

In atmospheric research, substances such as ozone and carbon dioxide are quantified using microwave radiometry, which measures the weak radiation emitted by the rotational transitions of molecules. Those emissions produce spectral lines with shapes that are a function of pressure, enabling the creation of altitude profiles for substances under investigation.

The frequency resolution of the measurement apparatus determines the maximum altitude at which volume mixing ratio profiles can be obtained. Overall measurement bandwidth determines the lower altitude limit.

Real-time fast Fourier transform (FFT) spectrometry is an alternative to the acousto-optical spectrometers (AOS) commonly carried aloft in observation aircraft. In comparative testing, a real-time system configured with Keysight high-speed digitizers provided comparable results and offered operational advantages: larger vertical range and better vertical resolution; equal or better dynamic range; and greater stability versus temperature and vibration.
