Abstract The EXO-200 experiment searched for neutrinoless double-beta decay of 136 Xe with a single-phase liquid xenon detector. It used an active mass 110 kg 80.6%-enriched in ultra-low background time projection chamber ionization and scintillation detection readout. This paper describes the design performance various support systems necessary detector operation, including cryogenics, handlin...

Portable, high-resolution gamma spectroscopy has long been a vital technique in routine safeguards accountancy. The high resolution enables the spectrum analysis to accurately determine the isotopic content of the sample. All currently deployed systems for this application are based on liquid-nitrogen cooled, high-purity germanium (HPGe) detectors, with the spectrum analysis performed on portab...

Alkali atoms trapped in solid hydrogen matrices have demonstrated ultralong electron spin coherence times and are promising as quantum sensors. Their is limited by magnetic noise from naturally occurring orthohydrogen molecules the parahydrogen matrix. In gas phase, component of can be converted to flowing it over a catalyst held at cryogenic temperatures, with lower temperatures giving fractio...

Peak purity analysis is an evaluation technique for detecting the presence of coeluting impurities in highperformance liquid chromatography (HPLC) data. Running a peak purity check prior to analytical quantitation helps to ensure accuracy. In the development of analytical methods, peak purity analysis can reveal the presence of contamination during standardization and, by doing so, can prevent ...

A quantitative analysis of the individual compounds in tobacco essential oils is performed by comprehensive two-dimensional gas chromatography (GC x GC) combined with flame ionization detector (FID). A time-of-flight mass spectrometer (TOF/MS) was coupled to GC x GC for the identification of the resolved peaks. The response of a flame ionization detector to different compound classes was calibr...
