New Portable Device for Automated Radon Detection
The Spanish National Research Council (CSIC), through the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC), has collaborated in the design and development of a prototype for the detection of radon gas, a naturally occurring radioactive gas that can be found in the interior spaces of buildings. It consists of a small device that connects to a wireless network and automatically monitors radon levels in its environment in buildings. This detection system contains a silicon sensor manufactured in the Clean Room of the IMB-CNM-CSIC.
The prototype, still in the standardization phase, is the result of the CARE project, an initiative that has been led by the company Alibava Systems and has had the participation of two public research centers, the IMB-CNM-CSIC and the Instituto Galego de Física de Altas Enerxías (IGFAE) of the Universidade de Santiago de Compostela, which has been responsible for carrying out the calibration and validation tests, both in its experimental facilities and in real environments. CARE also involves three companies, ATI Sistemas SL, Radiansa Consulting SL, Sensing & Control Systems SL.

Compact Tracking Telescope for High Energy Particles
OVERVIEW
The ALIBAVA Telescope has been successfully operated at the DESY and CERN-SPS beam lines.
The telescope consists of at least three planes (stations). The stations use ALIBAVA daughter boards to take the tracking information from two 90 degrees-turned strip sensors for XY positioning. The stations act as reference frame and allow precise track reconstruction. Each daughter connects to an ALIBAVA motherboard to process the information and they to a unique master board that synchronizes and controls the whole system. The system is triggered by two scintillators located at both ends.
Several devices can be tested simultaneously. Analysis of charge collection, cluster width, efficiency, resolution, time profile and other parameters of the devices under test with the software provided.
The telescope provides accurate particle tracking and hit point projection on device under test.

What is a Kelvin probe?
The Kelvin probe is a non-contact, non-destructive vibrating capacitor device used to measure the work function (wf) of conducting materials or surface potential (sp) of semiconductor or insulating surfaces. The wf of a surface is typically defined by the topmost 1 - 3 layers of atoms or molecules, so the Kelvin probe is one of the most sensitive surface analysis techniques available. KP Technology systems offer a very high wf resolution of 1 - 3 meV, currently the highest achieved by any commercial device.
The Kelvin probe does not actually touch the surface; rather an electrical contact is made to another part of the sample or sample holder. The probe tip is typically 0.2 - 2.0 mm away from the sample and it measures the 'traditional work function', i.e. that found in literature tables. Other techniques, using very sharp tips some 10's of nanometers away from the sample, measure very reduced and distorted work functions due to the close separation of tip and sample.

Didactic Kits for University of Fribourg
During Q1/2012 they will be receiving two new Educational Kits & Experiments for training students with state-of-the-art didactic tools from CAEN, world leader in nuclear and particle physics instrumentation.
SP5700-EasyPET in this tutorial, is a simple, user friendly and portable didactic PET system developed for high-level education, which allows exploring the physical and technological principles of the conventional human PET scanners, using the same basic detectors of state-of- the-art systems. The Positron Emission Tomography (PET) scanner is the state-of-the-art medical imaging system, capable of providing detailed functional information of physiological processes inside the human body. Functional imaging has a great impact in cancer diagnostics, monitoring of therapy effects and cancer drug development. The underlying principle to PET systems is the detection of high energy radiation emitted from a chemical marker, a molecule labelled with a radioisotope, administered to a patient. The radioisotope emits positrons which, after annihilating with atomic electrons, result in the isotropic emission of two photons back to back with an energy of 511 keV. The two photons are detected by a ring of detectors, which allows a pair of them to detect two back to back photons in any direction.

Ф4 Ultra-high Vacuum Scanning Kelvin Probe
The Ф4 Ultra-high Vacuum Scanning Kelvin Probe system gives the user full access to work function measurements under vacuum with the ability to alter the temperature from 77 K to 860 K. The Kelvin probe measurement has resolution of 1 - 3 meV for a 2 mm tip on a conducting sample. The sample is mounted on a plate that is located on a motorized (x, y, z) translator attached to a stainless steel vacuum chamber. Phi 4 also comes with a photoemission spectroscopy system with a tunable source (3.4 - 7.0 eV). The deep ultra-violet (DUV) light spot measures approximately 3 x 4 mm. Absolute work function measurements can be obtained with this system in the range of 4.0 - 6.5 eV with an accuracy of 0.05 - 0.1 eV.
The system can be upgraded with surface photovoltage spectroscopy through utilizing other ports in the system chamber. Liquid nitrogen is used as the method of cooling the sample and heating is achieved by controllable direct current. Nitrogen gas is used to displace the oxygen to facilitate the use of the photoemission system source. An optical breadboard is used to support the chamber and standard power is required for operation.

2019 Nobel Prize in Physics
Exoplanets, or extra solar planets, are planets beyond our solar system. This 4 minutes National Geographic video explains their discovery and significance.
In 1995, Professor Michel Mayor and his doctoral student Didier Queloz discovered 51 Pegasi B, a planet orbiting a sun-like star beyond our solar system. Their discovery created great interest in the field and research since then has led to the discovery of around 4,000 exoplanets, some of which might support life. Proxima Centauri b, the closest potentially habitable exoplanet, is 40 trillion km (4.2 light years) from earth.
A 4th physicist, John Goodenough, shared the Chemistry award with Stanley Whittingham and Akira Yoshino for the development of lithium-ion batteries.

Experiment to Detect Dark Energy Turns Up Nothing
The accelerated expansion of the universe motivates a wide class of scalar field theories that modify general relativity (GR) on large scales. Such theories require a screening mechanism to suppress the new force in regions where the weak field limit of GR has been experimentally tested. The scientists used atom interferometry to measure the acceleration of an atom toward a macroscopic test mass inside a high vacuum chamber, where new forces can be unscreened. The measurement show no evidence of new forces, a result that places stringent bounds on chameleon and symmetron theories of modified gravity.

VES-210 Production Vacuum Exhaust & Gas Backfill System
Our latest shipment is a Vacuum Exhaust Station (VES-210) with gas backfill capability for an EU production plant of a very large multinational instrumentation firm.
xtronix custom designs removes the burdensome task of design engineering, parts procurement, assembly, testing and final qualification. We work with trusted suppliers, often companies we actively distribute products of, leaving our customers more time to focus on their own clients and less on worrying about all the intricacies of custom designs.
Past custom designs have varied from components as vacuum feedthrough assemblies for radar or night vision devices to Pirani vacuum gauges, cryostats, sputter coating and gas blending systems.
The VES-210 pictured here can be used for production of gas-backfilled devices typically as used in X-ray collection techniques such as X-ray Fluorescence / Diffraction products, or in the manufacture of appendage ion pumps, small communication devices or other pinch-off cavities. This concept can be expanded to a VES-310, -410 or reduced to a VES-110 concept.
High vacuum is achieved by a turbo-molecular pump with a scroll backing / roughing pump.
The vacuum cycle is fully automated via a touchscreen, menu-driven controller. Vacuum and gas hardware is stainless steel throughout and the vacuum components are mostly right out of our own 88-page vacuum components catalog. The system conforms to CE norms.
