TRIUMF
Postdoctoral Fellow, Gamma-Ray Spectroscopy
Located in Vancouver on the south campus of the University of British Columbia, TRIUMF is Canada's national research facility for particle and nuclear physics. We currently have an immediate opening for a Post-Doctoral Fellow (PDF) to join our Gamma-Ray Spectroscopy at ISAC (GRSI) group, which is involved in a number of programs investigating a variety of nuclear structure, nuclear astrophysics, and fundamental symmetries topics at TRIUMF's Isotope Separator and Accelerator (ISAC) ISOL radioactive beam facility.
The GRIFFIN spectrometer has now begun scientific operation with early-implementation experiments completed in 2014. GRIFFIN represents a significant upgrade to the decay spectroscopy capability with stopped radioactive beams at ISAC-I. GRIFFIN consists of an array of 16 large-volume HPGe clover detectors and a state-of-the-art custom-designed digital data acquisition system which enables our research programs in nuclear structure, nuclear astrophysics and fundamental symmetries. A major component of this program includes precision measurements of Fermi super-allowed beta emitters. The GRIFFIN spectrometer is complemented by a powerful suite of ancillary detector systems including plastic-scintillators for beta coincidences, LN2-cooled Si(Li) detectors for conversion electron measurements and an array of eight LaBr3 scintillators for fast-timing measurements. In addition, GRIFFIN will couple to the DESCANT array of neutron-detectors for beta-delayed neutron emission studies with neutron-rich beams.
Our group also operates the TRIUMF-ISAC Gamma-Ray Escape Suppressed Spectrometer (TIGRESS), a state-of-the-art gamma-ray spectrometer for experiments with accelerated radioactive ion beams provided by the ISAC-II superconducting linear accelerator. Experiments can be performed with the combination of TIGRESS and the Silicon Highly-segmented Array for Reactions and Coulex (SHARC) detector which offers excellent energy and angular resolution for charged particles. The combination of TIGRESS and SHARC offers a powerful tool for detailed nuclear structure and astrophysics investigations. A number of other ancillary detector systems are also being brought online at this time including the TIGRESS Integrated Plunger (TIP) for lifetime measurements of excited states, the SPICE detector for in-beam conversion electron measurements and the EMMA recoil mass separator.
Specific responsibilities will include:
- Working on the setup, optimization, operation and maintenance of the spectrometers and digital data acquisition system
- Taking a lead role in experiments with the devices that our group operates at ISAC, including GRIFFIN and TIGRESS
- Disseminating results as articles in peer-reviewed scientific journal and through presentations at national and/or international conferences
- Directly supervising undergraduate and/or graduate students
Minimum qualifications include:
- PhD in experimental nuclear physcis, or expected completion date of March 2015
- Extensive knowledge of nuclear science, radiation measurement and the operation of radiation detectors
- Experience in performing gamma-ray spectroscopy is preferable
