  • Perform duties of Instrument Maker II. 
  • Perform related duties as required.

 

Minimum Qualifications:

  • Two years of experience as an Instrument Maker II OR Equivalent education/experience.
  • Proficiency in close-tolerance manual machining, including use of mills, lathes, drill presses, grinders, saws and hand tools.
  • Proficient in CNC programing.
  • Proficient at operating CNC mills and lathes.
  • Proficient at welding, brazing, and soldering.

Intermediate skill level with a CAD program. Inventor preferred.

 

Desired:

  • Ability to make clear presentations, write reports and document procedures.
  • Ability to work successfully on multiple concurrent projects, and to work with a team.
  • Knowledge of the machinability of metals, ceramics, plastics and composites and silicones.
  • Ability to estimate job cost per design and to suggest value-engineering enhancements that minimize time and cost.
  • Ability to document procedures.
  • Ability to carry out load and stress calculations of components.
  • Openness to novel concepts of research apparatus, methods, and procedures and ability to find solutions to problems.
  • Experience with liquid cryogens, preferably including liquid helium.
  • Familiarity with compressors and expanders.
  • Vacuum system assembly, including machining knife edge seals for CF gaskets, vacuum tight welding, and troubleshooting vacuum leaks.

CENPA Postdoctoral Position in Fundamental Symmetries and Neutrinos

The University of Washington Center for Experimental Nuclear Physics and Astrophysics (CENPA) has two openings for Postdoctoral Scholars to work on the LEGEND and He6-CRES experiments.

LEGEND is one of the leading experiments searching for neutrinoless double-beta decay. Its first phase, LEGEND-200, is under construction at Gran Sasso Laboratory in Italy, and will be taking data in 2022. UW leads the LEGEND data analysis and also performs detector R&D with local test stands. A new Postdoctoral Scholar will be in an excellent position to participate in the initial LEGEND-200 data taking and analysis, as well as contribute to the planning for LEGEND’s ton-scale phase, LEGEND-1000, and the development of additional physics opportunities offered by this unique experiment.

He6-CRES is an experiment to search for scalar and tensor currents by measuring beta spectra from 6He, 19Ne, and 14O, using the CRES technique for determining beta energies via measurement of their cyclotron radiation in a magnetic field. The decay nuclei are produced using our local accelerator. The goal is to achieve record sensitivity for Beyond-Standard-Model weak currents and to develop applications of the CRES technique for nuclear physics.

CENPA is a fertile environment for experimental nuclear physics, with active participation in KATRIN, Project8, Selena, DAMIC, COHERENT, Muon g-2, MuSun, PIONEER, ADMX, searches for deviations of the laws of gravity, and other experiments.

The initial appointment is for one year, expected to be renewed on a yearly basis for up to three years, subject to funding and mutual agreement. The preferred start date would be in the Winter or Spring 2022. The Postdoctoral Scholar title is limited to five years, including postdoctoral experience(s) at UW and other institutions.

Postdoctoral Scholars are represented by UAW 4121 and are subject to the collective bargaining agreement, unless agreed exclusion criteria apply. For more information, please visit the University of Washington Labor Relations website.
 

Qualifications

We seek creative, conscientious, and highly motivated applicants, with preference for those having previous experience in one or more of the following topics: neutrinoless double-beta decay searches, neutrino or dark matter detection experiments, low radioactive background techniques, software development in python/numpy/scipy/numba and C++, particle physics Monte Carlo simulations, data analysis, statistical analysis, radiofrequency electronics, digitization, and fast-data acquisition.

Applicants are required to have obtained or have completed all requirements for the degree of Ph.D. (or foreign equivalent) in nuclear physics, particle physics, astronomy, or a related field within the last 3 years and before the start of the appointment.

Postdoctoral Scholar – DAMIC-M

We invite applications for a Postdoctoral Scholar position in the areas of experimental astroparticle and nuclear physics in the Physics Department at the University of Washington (UW).

The UW is the lead institution in the construction of the DAMIC-M detector, which will search for light dark matter particles with unprecedented sensitivity.

The DAMIC program also includes smaller prototype detectors that will begin taking data underground by the end of 2021.

We seek a creative, conscientious, and highly motivated candidate to spearhead the activities in the construction and commissioning of DAMIC-M. In addition, the appointee will have the opportunity to participate in the data analysis of the prototype detectors, and the R&D program at the UW to develop next-generation skipper CCD detectors (Oscura) and CMOS/selenium detectors for neutrino physics (Selena). The postdoctoral position will be based in Seattle within the Center for Experimental Nuclear Physics and Astrophysics (CENPA), which provides world-class engineering and technical support.
