Kinetics of Protein Dynamics
Kinetics of Preotein Dynamics Customer Case The customer is measuring kinetics of protein dynamics with a time scale of between a few nanoseconds and about a hundred milliseconds. The customer's two response signals occur after a few-nanosecond-pulse excitation that repeats at a rate of 1-10Hz. This requires a bandwidth from DC to a few hundred MHz, sampling speed of about 1-2GS/s, and processing time for one acquisition that is less than 1-0.1secs. An analog signal of about 10-30mV comes from a Photo-Multiplier Tube (PMT) or a photo-diode with a trans-impedance pre-amplifier. The customer is currently using a couple of [...]
Radioactive Nuclear-Decay Detection
Radioactive Nuclear-Decay Detection Customer Case The customer has a requirement for PC-based waveform digitizer cards to digitize shaped pulses derived from nuclear-decay detectors. These pulses vary in their rate (frequency of occurrence) and amplitude. Their shape is approximately Gaussian with a full-width at half the maximum amplitude (FWHM) of 3-5 microseconds. The characterization of each pulse is critical for the accurate and precise determination of the activity of radioactive materials. These materials have very low count-rates (0.02 pulses per minute) to relatively high count-rates (>1000 pulses per minute). Important to the measurement process are the speed and reliability of [...]
Neutrino Detection System
Neutrino Detection System Customer Case Neutrinos are tiny (possibly massless) neutral elementary particles which interact with matter via the weak nuclear force. The weakness of the weak force gives neutrinos the property that matter is almost transparent to them. The sun, and all other stars, produce neutrinos copiously due to nuclear fusion and decay processes within the core. Since they rarely interact, these neutrinos pass through the sun and the earth (and you) unhindered. Other sources of neutrinos include exploding stars (supernovae), relic neutrinos (from the birth of the universe) and nuclear power plants (in fact a lot of [...]

MTI Application Note: Testing for Connector Failure Due To Vibration or Shock
Testing for Connector Failure Due to Vibration or Shock Mobile Communications Equipment Needs Reliable Connectors That Will Not Disconnect with Shock or Vibration Introduction A large multinational company approached MTI to provide a sensor capable of measuring displacement that also wouldn’t load the target (connector). Shock and vibration testing would span 2-15G and the target connectors were very small. Application MTI’s 2100 optical displacement sensor system is ideal for this kind of application because very small probes can be used and they measure displacement via reflected light. [...]

MTI Whitepaper: Easy Roller Gap Measurement Ensures Calendering Success
Easy Roller Gap Measurement Ensures Calendering Success Many roll-to-roll finishing processes typically use a calender, or series of hard pressure rollers, to deliver smooth, high-quality products of plastic, textile, or paper (Fig 1). Ensuring a consistent material thickness, however, depends on the ability to monitor, and maintain, a precise gap between rollers. This application note describes a quick and easy means for roller gap measurement Problem Establishing a roller gap and checking for parallelism across roller width can be a slow and cumbersome procedure. Manual measurement requires multiple sized feeler gauges which can introduce errors. Misinterpreting [...]
Nuclear Particle Location
Nuclear Particle Location Customer Case The customer studies nuclear particles traveling in an electrically charged medium. The particles emit two types of short 53 MHz signal bursts. The first type lasts for 1.6 ms, the second type lasts for 6 ms. The customer had to capture these bursts in at least two locations and analyze their amplitudes in order to determine the position and some of the characteristics of the nuclear particles. The application requires two channels of capture at speeds of at least 500 MS/s. The depth of capture at 1 GS/s is 6,000 samples for the 6 [...]
Application Note: How to Ensure Your LED Lighting Products Meet Industry Standards
Testing for performance, energy effeciency, consumption verification, quality and safety compliance during product development. Introduction Manufacturers and users of LED lighting products need to ensure that their products meet the qualifications and requirements of a multitude of reliability and efficiency standards. In addition to voluntary initiatives and programs like EnergyStar, mandatory standards and specifications for the lighting industry must be kept in mind during project development, including the latest IES LM-79-19 and the ANSI C82.16 documents. This application note provides an overview of relevant lighting standards and specifications for LED lighting products. [...]
