Job number TR20-2-11

Position Title:

Hyper-Kamiokande/NuPRISM Photosensor Researcher  

Name of Project:

Development of a New High-resolution Photon Detector for the Hyper-Kamiokande and NuPRISM Detectors 

Overview:

Neutrino oscillations are the only experimentally verified observation of a process not described by the Standard Model (SM) of particle physics. Since their discovery in 1998 we have learned a lot about the parameters that govern these oscillations, but there are still many questions remaining. Perhaps the most exciting of these is to determine whether neutrino oscillations violate charge-parity (CP) symmetry, and so could potentially explain why we live in a matter-dominated universe.

The NuPRISM detector is a part of the next generation of Hyper-Kamiokande neutrino experiment in Japan. Hyper-K will be a successor to the successful Super-Kamiokande and T2K experiments. The Hyper-K experiment is now approved and moving towards the construction phase with an expected start in 2028. It will be a powerful tool for exploring neutrino oscillations, as well as other phenomenon such as proton decay. The Canadian group is working on a number of interesting R&D efforts aimed towards the NuPRISM detector and Hyper-K projects.

The goal of this particular project is to assist in the development of a new type of photosensor for NuPRISM. This is the multi-PMT: a series of 3" PMTs are placed inside a transparent pressure vessel with the digitizing electronics. For this project you will be helping to finalize and update the mechanical design of the multi-PMT, and to construct and test the first prototypes of the multi-PMT.

The work will include optimization of the mechanical design for the multi-PMT using CAD tools, overseeing the production of parts with TRIUMF or commercial partners, quality control of parts, and assembly of parts into the multi-PMT module. The multi-PMT assembly work will be carried out with the goal of developing automated procedures to optimize the eventual mass production of the multi-PMTs. The work may also including testing of the multi-PMTs to characterize their mechanical, electrical and photon detection performance.

Duties:

- Optimization of the mechanical design for multi-PMTs based on the experience of the ongoing prototype program.

- Overseeing the production of multi-PMT prototype parts using 3D printing, the TRIUMF machine shop and commercial partners.

- Assembly of the multi-PMT prototypes and development of optimized and automated assembly procedures to maximize the efficiency and quality of multi-PMT assembly.

- Testing of multi-PMT prototype modules to characterize their mechanical, electrical and photon detection properties.

Skills learned during this work experience:

- Experience in design and construction of mechanical systems.

- Experience with computer aided design tools and stress analysis.

- Experience in parts fabrication methods, including 3D printing.

- Experience in quality control for parts production.

- Critical thinking and problem solving.

- Presentation skills from reports in regular meetings at national and international levels.

Qualifications:

We are looking for a motivated mechanical engineering or physics engineering student to work on an exciting high-energy physics project. The core skills that we are looking for include:

- Strong competence in the design, simulation, assembly and testing of mechanical systems.

- Ability to quickly learn several new computer tools and software packages.

- Basic programming skills.

- Ability to independently solve problems and investigate alternatives.

Beneficial skills would include:
- Experience with using Linux OS would be very beneficial.

- Experience with standard CAD software tools.

- Understanding of the basics of a particle physics detector, particularly of photo-multiplier tubes.

- Familiarity with modern fabrication techniques and materials.

Shiftwork required:

No

Period of work:

May - Aug 2020 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.
