DESY, short for Deutsches Elektronen-Synchrotron, is based in Hamburg, Germany and operates particle accelerators to investigate the structure of matter. The accelerators run 24/7 for international experimenters so it is vital to have equipment that can be relied on to work perfectly and for many years. Spectrum Instrumentation has become one of DESY’s suppliers of choice for digitizer cards for the past fifteen years because of its reputation for quality.

The ability to focus waves offers interesting possibilities in a number of fields such as communications, ultrasound, nondestructive testing (NDT), medical science and audio. For example, in biomedical applications, focused ultrasound can be used in lithotripsy procedures for treating kidney stones or to target brain tumors. Similarly in NDT, the TR process has been used to help locate and characterize defects in solid materials. In addition, it can be used to create high amplitude focusing of ultrasound for a non-contact source used for nondestructive evaluation.

The request was for a complete solution for portable recording of dynamic mixed mode (analog and digital channels) data during test drive. The data should be replayed and analyzed later in Research and Development laboratory. A full working system including operation software was needed.

The Stuttgart University has chosen a Spectrum Arbitrary Waveform Generator for their experiments in which single atoms in a diamond are replaced by nitrogen atoms. This method is a base for applications like a magnetic field detector at the atomic level or a qubit in a quantum computer.

Precision is always important in research and there can be few research areas needing greater precision than that of quantum research. The Institute for Quantum Optics and Quantum Information at the University of Innsbruck, Austria needed an Arbitrary Waveform Generator (AWG) to generate a wide variety of signals for their research.

Industrialization in the modern world has become the primary cause of environmental atmospheric pollution. As such, the study of industrial pollution, and its various components, has become a major area of importance. For example, in China the Ministry of Environmental Protection has stipulated the monitoring of atmospheric levels for sulfur dioxide (SO2) and oxides of nitrogen (NOx), which are the common dangerous emissions found near industrial zones.

The International MegaGauss Science Laboratory is part of the Institute Solid State Physics (ISSP) at the University of Tokyo. The objective of the laboratory is to study the physical properties of solid-state materials (such as semiconductors, magnetic materials, metals, insulators, superconducting materials) as they are subjected to ultra-high magnetic fields. The fields are also used for researching new materials and controlling their phase and functionality. The laboratories pulse magnets can currently generate up to 87 Tesla (T) by non-destructive methods, and from 100 T up to 760 T (currently the world record for the strongest field generated in-doors) by a destructive process.

Fusion has long been viewed as the ultimate goal for energy generation. Smashing together deuterium and tritium atoms releases energy as they combine and is the reaction at the heart of the sun. With no dangerous waste products and a virtually limitless supply of these atoms from seawater, billions have been spent on fusion research. However, recreating the extreme conditions of temperature and pressure on earth are not easy. A British company called First Light Fusion (FLF) is pioneering a very different approach to fusion and is on target to achieve fusion gain – more energy out than goes in – by 2024. In order to achieve the conditions needed for fusion, they launch a projectile to hypervelocities at a target which requires very high levels of precision to achieve and so they selected 32 digitizers from Spectrum Instrumentation to monitor the results.

Cell sorting plays a fundamental role in molecular biology, pathology, immunology and virology research. It requires the ability to rapidly search through and sort out cells based on their unique chemical features and shapes. Conventional methods are limited in uncovering these differences, or are too labor or time intensive, or have to tradeoff between speed and accuracy. The Department of Chemistry at the University of Tokyo has developed an intelligent Image-Activated Cell Sorter (IACS) with an ultra-fast Spectrum Instrumentation digitizer at the heart.

The VivoSight® OCT scanner uses the technique of swept-source Optical Coherence Tomography (SS-OCT) for cross-sectional imaging of skin. This is a significant new tool to assist in diagnosis and treatment of skin cancers and other skin conditions.
