Position Title:TRIUMF Neutral Atom Trap for beta decay Student Research Assistant | ||
Name of Project:TRIUMF Neutral Atom Trap for beta decay: Search for new interactions | ||
Overview:We use laser trapping and cooling techniques to study beta-decaying isotopes. The pressure of laser light traps the radioactive atoms in a 1 mm-sized cloud. The daughter nuclei have very low kinetic energy, and would stop in ten atomic layers of material. But they freely escape the trap, and we can measure their momentum. If we do this in coincidence with the emitted electron, we can deduce the (otherwise invisible) neutrino momentum. This lets us do several unique experiments (see Behr and Gwinner, arXiv:0810.3942).We are developing a trap with stable isotopes to spin-polarize the nuclei. Applying those techniques eventually to beta decay, we can measure the asymmetry in emission of neutrinos with respect to the spin, and test whether the neutrino helicity is always left-handed. There may also be preparation work on vacuum systems for trapping the heaviest alkali atom, francium, which has no stable isotopes. Goals are atomic spectroscopy studies for its own sake, and parity-violating interactions in atoms to study the weak interaction. | ||
Duties:There are several separate tasks, and student duties will depend on interest and experience.We will assemble and test a new ultra-high vacuum chamber to house detectors. We will then test our new atom trap techniques there. That will include a careful characterization of time-dependent magnetic fields, and measurements of the spin polarization produced in stable atoms by absorption of circularly polarized light. In parallel, we will be testing and developing detectors for the low-energy ions and the electrons. | ||
Skills learned during this work experience:Ultra-high vacuum techniques, real-time control of electro-optical devices, laser spectroscopy, fast switching of magnetic fields, particle detectors. | ||
Qualifications:Physics or Engineering Physics student with at least 1 previous work term is strongly preferred. C or C++ programming skills, optics course and/or lab, and quantum mechanics coursework would be considered assets. Some electronics analysis and assembly experience would be useful. | ||
Shiftwork required:Yes | ||
Period of work:May-August 2010 with possible 4-month extension | ||
Salary is commensurate with academic progress and previous relevant work experience, and
ranges from $ 2080 to $ 2800 per month plus 4% vacation pay. TRIUMF pays round-trip airfare (this does not apply to Vancouver/Victoria students); for Vancouver Island students, TRIUMF will pay ferry costs.
