1254. Cloud Point Extraction of Plutonium in Fish Tissues Coupled to Alpha Spectrometry

Ms Alexa Leblanc (Chemistry Department, Laval University)

Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)

A cloud point extraction procedure was developed to quantify the plutonium in environmental samples. This procedure uses a selective ligand within micelle which will complex with the element to be extracted. The extraction is effective in highly acidic solution with the addition of bromine in the system thereby forming a shield around the micelles. In this study, this procedure is used to...

1321. Towards sequential and automated CPE methods to pre-concentrate and extract radionuclides from environmental matrices

It can be challenging to measure the concentration of radionuclides using mass spectrometry when these concentrations are in the “parts per trillion” range. Yet, radionuclides can cause health problems even at these low concentrations, especially alpha-emitting radionuclides with a short half-life. This is why we are developing a methods to rapidly extract and pre-concentrate radionuclides at...

1266. A Primary Cold-Atom Based Vacuum Pressure Standard

Instrumentation and Measurement Physics / Physique des instruments et mesures (DIMP-DPIM)

Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)

Laser cooling and trapping of atoms has created a revolution in physics and technology. For example, the GPS network used for global navigation relies on cold atoms for time keeping. This poster will review the recent advances of our research program which is aimed at creating a cold-atom based primary pressure standard for the high-, and ultra-high vacuum regimes. Cold, trapped atoms can act...

1259. RF-Compressed Ultrafast Electron Diffraction: Long-Term Sub-50 fs Phase Stabilization in High-Brightness Instruments

Martin Otto (McGill University)

14/06/2016, 19:06

Instrumentation and Measurement Physics / Physique des instruments et mesures (DIMP-DPIM)

Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)

Ultrafast electron diffraction is a powerful table-top technique to characterize structural dynamics in condensed matter. We present an analysis of the phase stability of a 3 GHz radio-frequency electron pulse compression cavity. We implement low-noise microwave phase detection electronics to measure the slow drift (greater than 1 s) of the cavity resonance, allowing for continuous feedback...

1420. Gas Source Development for Accelerator Mass Spectrometry

Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)

Caesium sputtered ion sources when used on solid graphite powdered samples have been thus far - capable of generating a peak negative (_6^12)C-beam current of around 200-400 µA (~〖10〗^15 ions/s). However, when using CO2 gas directly as the carbon source – less of the sample is lost during the graphitization process, which is of vital importance when one has a limited amount of the material...
