Scienta Sensor Systems' SAUNA III 

The Ultimate Sensor for Early Warning and Emergency Preparedness for Nuclear Events 

June 2, 2020

Scienta Sensor Systems, a business area in the Scienta Scientific Group, offers solutions to detect nuclear events. They supply the internationally accredited Swedish Automatic Unit for Noble Gas Acquisition (SAUNA) system, an ultrasensitive system for remote detection of airborne radioactive xenon. 

SAUNA systems have the unique capability to detect, localize and characterize remote nuclear fission events, such as nuclear explosions or abnormal operation of nuclear power plants, by sampling radioactive xenon from the atmosphere. In 2020 the new generation, the SAUNA III, became commercially available as an upgrade of SAUNA II or as a completely new system. The SAUNA III is the most sensitive commercially available radionuclide detection system in the world.

The concept for automatic sampling for xenon isotopes was developed by the Swedish Defence Research Agency (FOI) during the 1990s and became the first SAUNA system in 2004. The project was initiated to meet the Comprehensive Nuclear-Test-Ban Treaty Organisation’s (CTBTO) global need for long-term, unattended, ultrasensitive, long-distance monitoring of nuclear explosions. Scienta Sensor Systems is a key supplier to CTBTO and works in a strategic partnership with the Swedish Defence Research Agency, drawing on more than 20 years of xenon detection expertise. Scienta Sensor Systems has also applied its own expertise and industrial skills to build a wide range of complementary products in the field.

SAUNA systems provide near real-time measurements from air samples and feed data into global or national data centres. Independent customers, such as national radiation protection agencies, are also installing the systems into their radiation protection networks for early warning and emergency preparedness.

Today Scienta Sensor Systems manufactures, installs and services SAUNA systems around the world. By having the largest installed base of noble gas monitoring systems globally, Scienta Sensor Systems helps to make the world a safer place.

The Latest SAUNA III Innovation

The recently released SAUNA III system sets a new standard for xenon detection sensitivity. The SAUNA III is a fully automated radionuclide continuous monitoring system that is capable to perform uninterrupted sampling, processing, quantification, and activity measurement of the four short lived xenon isotopes 133Xe, 135Xe, 133mXe, and 131mXe.

The major improvement of the SAUNA III is the doubling of processing capacity from 2 to 4 cycles per day, which increases the time resolution of the data from 12 to 6 hours. The minimum detectable concentration of xenon isotopes has also been significantly improved, meaning that lower levels of radiation can be detected than by previous SAUNA models.

The SAUNA III is now available to be purchased as a standalone system for new customers, or as an upgrade package to convert a current SAUNA II system to the new detection level for existing customers.

  • Scienta Omicron’s first DA20 analyser has been shipped!

    March 20, 2020

    During 2019 Scienta Omicron developed and released a new electron analyser for ARPES and XPS, the DA20. The new DA20 is designed not only to avoid sample rotation, but is also optimised for the measurement of photoelectrons with low kinetic energies, making it a great product for time resolved ARPES (tr-ARPES).

    During 2019 Scienta Omicron developed and released a new electron analyser for ARPES and XPS, the DA20. “Drawing upon the strengths of the DA30-L and its patented ground-breaking deflection technology, the DA20 received a completely new lens design that brings deflection capability to a new family of compact analysers. If you are looking to expand your research group’s capability with ARPES, the DA20 is an excellent choice,” says Scienta Omicron CEO Johan Åman. The new DA20 is designed not only to avoid sample rotation, but is also optimised for the measurement of photoelectrons with low kinetic energies, making it a great product for time resolved ARPES (tr-ARPES).

    The deflection capability of the DA20 allows researchers to perform full cone ARPES measurements without sample rotation. By avoiding sample rotation experimental geometry between the excitation source, the sample, and the analyser is preserved, eliminating its influence on the results.

    Benefits of avoiding sample rotation:

    In the case of small flakes and excitation spots, any sample rotation will cause movements of the excitation spot on the sample and away from the flake.

    For polarised light sources avoiding sample rotation means that the polarisation direction relative to the sample surface stays the same.

    Intensity modulations due to changing matrix element effects due to sample rotation are avoided meaning they do not impact the results.

    Using deflection capability it becomes easier to navigate reciprocal space and fine tune the sample orientation, allowing for fast sample alignment with high precision and accuracy leading to easier interpretation of the measurements in less time. Reducing the total time for an experiment will reduce the amount of condensed gasses on the extremely cold sample surface and lead to clearer measurements.

    The new DA20 lens design is also optimised for measuring photoelectrons with low kinetic energy, while covering a large energy window. A typical example of this application is tr-ARPES, where it is important to take advantage of the low number of generated photoelectrons by reducing the necessity to scan the energy axis. Measuring the angular distribution of low kinetic energy electrons is challenging because they are very sensitive to any form of distortion (including lens aberrations and local electric fields). Maintaining a large energy window at these low kinetic energies requires managing chromatic aberrations. The DA20 lens design overcomes both the challenge of low kinetic energies and large energy windows making it an excellent instrument for tr-ARPES. Due to the short laser pulses in tr-ARPES the energy distribution of the pulse is broad which is perfectly compatible to the DA20’s energy resolution, making it a good alternative to the highest resolution analysers of the DA30-L type. The DA20 is also compatible with our newly released Delay Line Detector (DLD) allowing to extend the angular and energy resolved measurements with a precise timing for each signal event.

    The shipping of the first DA20 represents a major milestone for our team of engineers and software developers. It comes with PEAK, Scienta Omicron’s new control and measurement software. PEAK features a modular system architecture design, with component specific servers accessible via a network. The included graphical user interface builds upon the same PEAK API that can be accessed directly by our customers to remotely control the analyser with their own programs and to integrate the analyser with complex auxiliary experimental setups such as beam lines. The PEAK vision simplifies the integration of other types of equipment such as excitations sources and manipulators.

    Product Manager for the DA20, Dr. Timo Wätjen, says that, “We are excited about the first shipment of the brand new DA20 to our customer. Our team successfully overcame several challenges designing the completely new lens leading to a very versatile ARPES product. The DA20 provides both a good base for customers who want to add ARPES capabilities to their labs and for experts in the time resolved field. The DA20 can be installed into existing systems replacing analysers without deflection capability, or can be installed into a brand new system solutions such as the ARPES Lab or a Materials Innovation Platform (MIP).”

    Scienta Omicron now looks forward to the successful installation and first results coming from our customer’s research group using the DA20. “Scienta Omicron is very proud to bring the DA20 into the field of Nanotechnology and Surface Science research, and to support our customers to meet their research goals. The DA20 further strengthens Scienta Omicron’s position as supplier of choice in these fields,” says CEO Johan Åman.

Binghamton University – HAXPES Lab

Scienta Omicron is excited that our first HAXPES Lab System in the United States will be installed at Binghamton University.

Scienta Omicron is excited that our first HAXPES Lab System in the United States will be installed at Binghamton University. The HAXPES Lab at Binghamton’s Smart Energy Building will become part of their Innovative Technologies Complex. It was chosen because of its performance, convenience, reliability and varied research applications. The HAXPES Lab will allow researchers to get detailed information about a device or material without taking it apart or off-site.

Scienta Omicron’s HAXPES Lab sets the standard for laboratory based high energy photoelectron spectroscopy, as it is able to probe bulk sample properties and access deep core level electrons via photoelectron spectroscopy (XPS) without the need for a synchrotron end station.

Binghamton have big plans for using their HAXPES Lab, including, batteries, next-generation electronics, neuromorphic computing, and solar energy harvesting. An exciting feature of the HAXPES Lab is its size, making it perfect for longer term measurements and collaboration with private industry as it can fit into a standard research lab. This has the potential to open doors for new collaborative partnerships and new research advancements within the field of materials science.

Dr Louis Piper, Associate Professor of Physics at Binghamton, said that “Photoemission has long been a powerful technique for materials studies, but has been largely been limited to sterile, perfect crystals. [The HAXPES Lab] is very flexible and means we can measure real materials and devices even while they’re in operation. This tool means we’ll be able to make significant contributions in smart energy technologies.”
