Fast Maximum Likelihood Positioning for a Staggered Layer Scintillation PET Detector [PDF]

open access: yesarXiv
In this study, we propose a fast implementation of a Maximum Likelihood Positioning (MLP) algorithm to estimate the energy and identify the active scintillator pixel in staggered layer scintillation detectors for PET. The staggered layer design with pixelated scintillators enables the determination of the gamma's depth of interaction and facilitates an

YAP:Ce scintillator as an absolute ultracold neutron detector [PDF]

open access: yesarXiv
The upcoming UCNProBe experiment at Los Alamos National Laboratory will measure the $\beta$-decay rate of free neutrons with different systematic uncertainties than previous beam-based neutron lifetime experiments. We have developed a new $^{10}$B-coated YAP:Ce scintillator whose properties are presented. The advantage of the YAP:Ce scintillator is its

Radioassay by gas-liquid chromatography of lipids labeled with carbon-14

open access: yesJournal of Lipid Research, 1962
A method for radioassay of carbon-I4 labeled substances analyzed by gas-liquid chromatography is described. The column effluent is automatically fractionated by condensing the vapor in a series of cartridges filled with anthracene crystals coated with ...

Use of a filter-paper disk assay in the measurement of lipid biosynthesis

open access: yesJournal of Lipid Research, 1966
The precipitation by trichloroacetic acid (TCA) of radioactive lipids on disks of filter-paper, followed by extraction with TCA and water to remove soluble radioactive precursors, provides the means for a convenient assay for lipid biosynthesis.
