Nuclear Decay Experiment
Nuclear Decay Experiment Customer Case A customer wants to measure nuclear decay rates of various radioactive isotopes. With each nuclear decay, the isotope under study simultaneously emits a beta particle, which is a high-speed electron, and a gamma particle, which is a high-frequency photon of light. Beta particles are detected with an efficiency of over 90% by a proportional gas counter that surrounds the radioactive isotope. Surrounding only one quarter of the isotope, a sodium iodide scintillator crystal detects gamma particles with about 25% efficiency. When it impinges on the scintillator crystal, a gamma creates a flash of visible [...]

Electron Spin Resonance (ESR) Experiment
Electron Spin Resonance (ESR) Experiment Customer Case A customer has an Electronic Spin Resonance (ESR) experiment. ESR is based on the fact that the magnetic moment of an electron precesses in an applied magnetic field, not unlike a child's top in a gravitational field, at a well-defined frequency called the Larmor frequency. Electromagnetic radiation at the Larmor frequency, when impinging on such an electron, will be preferentially absorbed. This principle is identical to that employed in Nuclear Magnetic Resonance (NMR), where the atomic nucleus precesses. In NMR, Larmor frequencies are of order 100 MHz. Because the electron is 2000 [...]
Measuring the Step Height Thickness of Non- Woven Conductive Films
Establishing and maintaining product quality throughout the production process is a common challenge of all manufacturers. How does an organization ensure the optimal output from their production lines, especially in real time? Key to this is strong non-destructive measurement practices that can take place at various points along the production process. The case study below is an example of how this was done at Saint-Gobain to measure the thickness and density of foam materials. They engaged with MTI's team of experts as their current direction was proving cost-prohibitive. Saint-Gobain's R&D organization, led by Dr. Mickael Boinet, found a solution [...]
Nuclear Ion Testing
Nuclear Ion Testing Customer Case This customer is involved in nuclear ion testing. The pulse amplitudes of nuclear ions from a detector must be measured and sorted into a histogram, which will show the number of times a given amplitude was received. The customer wants a "multi-channel analyzer" capable of analyzing 4,000 to 8,000 "channels." In the customer's terminology, "channels" are actually histogram bins. The customer has pulses coming in at 20 - 30 ms minimum interval and needs to peak detect (calculate the maximum value of the pulse). Then, based on peak height, each is stored in a [...]
Measurements with Capacitance Gage for Sub-Nanometer Thermal Expansion Characterization
MTI Instruments contracted an independent Metrology expert to test and verify the performance of a new high resolution capacitance gauge. The Accumeasure HD has passed in house testing where its performance was tested against a commercial laser interferometer (See Application Note). Optical Metrology Solutions (OMS) was chosen based on their extensive experience and proximity to MTI’s manufacturing plant. OMS was tasked with designing a challenging experiment to verify the accuracy and resolution of the MTI Accumeasure HD capacitance system that could also be encountered in a typical customer application. Their experiment explored the ability to measure sub-nonometer thermal expansion [...]
Alpha Particle Counting
Alpha Particle Counting Customer Case A customer has to characterize a new design for a solid state alpha particle detector. The detector is essentially a silicon diode with a large area face. Because alpha particles, which are high-speed helium nuclei, are electrically charged, they interact strongly with matter and lose their energy quickly upon entering a solid. When an alpha particle decelerates within the depletion region of the diode, it creates electron-hole pairs. The carriers are collected by the diode's electrodes and create a measurable current pulse. The customer's experimental solid state detector has two implanted electrodes whose signals [...]
Laser Spectroscopy
Laser Spectroscopy Customer Case An academic researcher is studying the attenuation properties of different materials inside Laser cavities for applications in Laser Spectroscopy. The Laser pulses are generated by one Laser, and are then transmitted by mirrors into another cavity filled with gaseous material. In the second cavity, the light pulses are continuously reflected by opposite mirrors and their intensities are measured by a transducer which converts them into decaying pulses of 30 nanosecond width. The decay takes about 40 microseconds to settle. The researcher is required to capture the decaying pulses and save the captured data onto the [...]

How Aircraft Operators Reduce Downtime While “Sweating the Assets”
In a recent article called “UPS Gives Old Jets New Life,” Bloomberg reports how United Parcel Service (UPS) is replacing the cockpit computers on its Airbus SE freighters in order to reduce downtime, increase productivity, and avoid large capital expenses. Known as “sweating the assets,” this business strategy is also benefitting the two aviation maintenance repair and overhaul (MRO) organizations that are performing the computer upgrades. “Doing such work,” writes Bloomberg’s Thomas Black, “is a huge potential market.” As the article explains, UPS purchased flight computers for over 50 Airbus A300-600 jets some twenty years ago. However, the memory [...]
