Novel, high electron temperature pulsed microwave plasma / repetitive inkjet droplet based spectrometer for elemental analysis. High performance detection of Arsenic, Mercury, Lead as specifically targeting UV-emitting pollutant.

The purpose of this document is to introduce a new technical idea for consumer product PP-1: it is electronic device for close range (within 200m or so) tracking of children or people in other situations when tracking is needed. It can be also used for short-range navigation to/from fixed location.

This working paper introduces a multi-source energy harvesting powered acoustic emissions (AE) monitoring system for the applications of rotating machine fault detections. This wireless sensor prototype records the AE signal at approximately 200KHz frequency. It performs fast Fourier transform (FFT) and compares the results with known fault pattern...

A new silicon photomultiplier is fabricated for fast timing applications by SensL Technologies Ltd. This new family of silicon photomultiplier, herein referred to as fast SPM devices, is fabricated with a third terminal that has a low output capacitance to improve timing performance. Two fast SPMs (an N-on-P type and a prototype P-on-N type) are as...

Positron Emission Tomography (PET) procedure requires that a drug with a known biological activity is labelled with a positron-emitting nuclide and injected into a patient; the in vivo imaging of the radioactivity allows monitoring several biological pathways, hence assessing the health of the patient undergoing the exam. The radiopharmaceutical ne...

In this paper we report on a new silicon photomultiplier (SPM) architecture with additional signal output. This additional output has very fast single photo electron response (∼2 ns FWTM). This new device can be easily integrated into legacy systems by providing the ability to operate as a normal SPM with Anode readout or in new designs with an add...

We present the design for OpenPET, an electronics readout system designed for prototype radiotracer imaging instruments. The critical requirements are that it has sufficient performance, channel count, channel density, and power consumption to service a complete camera, and yet be simple, flexible, and customizable enough to be used with almost any...

The value of pre-clinical PET and MRI is established, and SPECT also is now routinely used in drug development, disease treatment, and molecular biology research. The aim of this research is to prepare and test imaging prototypes of both SPECT and PET with similar form-factors for use within the core of a pre-clinical MRI. To test the imaging prope...

Silicon photomultipliers are of great interest for scintillation light detection in gamma spectroscopy, due to their large gain and high speed. In this article we report about the use of a silicon photomultiplier for radiation detection and gamma spectroscopy. It is our goal to understand silicon photomultipliers to the extent that we could use the...
