We have designed and constructed a low-field TRASE RF imaging system. In TRASE k-space encoding is achieved by refocusing with RF phase gradients. The system includes a motorized rotatable magnet, twin RF power amplifiers, two geometric decoupled truncated twisted solenoid RF transmit coils (1D radial TRASE encoding), and a multi-channel transmit software-defined-radio console. The magnet is a...
Current mass spectrometry methods are typically not well suited to provide timely characterization of samples of interest in a threat investigation scenario. This limits their use by professional personnel to inform the best course of action in response to an event. A field-deployable, rapid, and accurate identification method for chemical, biological, radiological, nuclear and explosive...
Silicon photomultipliers (SiPMs) are emerging as the technology of choice for single photon detection in large-area experiments used in rare-event physics searches. The SiPM consists of a 2-dimensional array of tightly-packed single photon avalanche diodes (SPADs) with quenching resistor, biased above breakdown. Upon absorption of an incident photon, this generates a self-sustaining charge...
Many particle detectors that use liquid scintillators house it in an acrylic vessel. The acrylic may be coated by a wavelength shifter if the scintillation light produced from particle interactions is outside the wavelength range of the photodetectors. We have investigated the low-temperature properties of pyrene as an alternative to 1,1,4,4-tetraphenyl-1,3-butadiene (TPB) as pyrene has a much...
ne can go days without water and food but only a few minutes without air. Side effects of air pollutants have been well studied and documented. The results from these studies make it essential for us to monitor air quality. In this talk, we report the design of a small and low-cost yet efficient air quality monitor. The technique used is single-photon detection which is scattered off the...
