The Winter Nuclear and Particle Physics Conference is an annual Canadian meeting aimed at junior researchers, with the specific goal of facilitating interaction between the Nuclear and Particle Physics communities.

This year the conference took place in Mont Tremblant, QC, Canada, and was organized by Carleton University and SNOLAB. The conference included students and invited talks on dark matter, neutrino physics, and accelerator physics, as well as some spare time for skiing!

M.Sc. student Daniel Durnford (Queen’s University) represented NEWS-G at this conference, winning 2nd place for his talk about the recently published physics results from NEWS-G at LSM!

NEWS-G @ LAKE LOUISE WINTER INSTITUTE, Feb 18th – 24th, 2018

The Lake Louise Winter Institute meeting organized by the University of Alberta explores recent trends in particle physics in an informal setting. Held every year since 1986, it gathers physicists from various fields including particle accelerator physics, neutrino and dark matter physics. The institute is held at the Chateau Lake Louise, AB, Canada, in the Canadian Rocky Mountain range

This year, Quentin Arnaud (Queen’s University) reported on the recently published results of the NEWS-G experiment at the LSM on behalf of the collaboration.

NEWS-G @ UCLA DARK MATTER SYMPOSIUM, Feb 21st – 23rd, 2018

The UCLA Dark Matter symposium occurs every other year in Los Angeles, CA, USA. It brings together the best in theory and experiment on Dark Matter from all around the world.

This year, new theoretical models in both cosmology and particle physics were shown in the three-day conference, and many experiments were presented, be they running, under development, or planned for the future.

Philippe Gros (Queen’s University) gave a talk on behalf of the NEWS-G collaboration, presenting the detector concept, the recent results of SEDINE and the future plans at SNOLAB.

NEWS-G & the Dark Matter Day

On October 31, 2017, the world celebrated the historic hunt for dark matter. Global, regional, and local events were planned on and around that date by institutions and individuals looking to engage the public in discussions about what we already know about dark matter and the many present as well as planned experiments seeking to solve its mysteries.

At Queen’s University, Kingston, ON, Canada

The first international Dark Matter Day organized by CPARCCanadian Particle Astrophysics Research Center – (in collaboration with the Dunlap Institute – University of Toronto) and hosted by Queen’s University was held on October 23rd. The event included public talks featuring several astronomers and physicists who perform cutting-edge research on the subject of dark matter. Before and after the talks, interactive displays were delivered to the public by various dark matter research groups at Queen’s, including three NEWS-G members. Sean Crawford and Jacob Morrison exhibited a NEWS-G detector made of glass along with a live display of data acquisition from a functioning detector, while Daniel Durnford was in charge of presenting a poster summarizing the NEWS-G experiment. The event was a success, with over 200 people learning a bit more about dark matter!

On the 31st of October, CPARC provided a unique opportunity for 31 students (from grades 10-12) to discover the mysterious subject of dark matter. These students received an introduction to the topic from faculty and students working on dark matter search experiments at Queen’s University. Hadiya Ma, one of our undergraduate summer researchers, gave a presentation on her experience with the NEWS-G team and her adventure in studying physics at the university level, aiming to inspire the next generation of physicists!

Newest members @ NEWS-G

We recently welcomed some new faces to the Queen’s University team and as new members of the collaboration, they are going to introduce themselves…

Philippe Gros

“I’m a researcher with a long experience with gaseous detectors, and in particular Time Projection Chambers. I started in Lund, Sweden, with the ALICE TPC at LHC, equipped with MultiWire Proportional Chambers (MWPC). I worked for the International Linear Collider (ILC) project in Saga, Japan, on the TPC prototype equipped with Gas Electron Multipliers (GEMs). Finally, in Palaiseau, France, I used the HARPO TPC, equipped with Micromegas, to measure the polarisation of a gamma ray beam. As a Research Scientist at NEWS-G, I will oversee the operations of the test facility at Queen’s University, as well as the installation, operation and scientific exploitation of the experiment at SNOLAB.” Philippe Gros, Research Scientist

.
Carolyne Neron“As the new Project Manager for NEWS-G, my main role is to provide assistance to the team in the planning, estimating and execution of the experiment at SNOLAB. I coordinate with work package leaders to provide inputs to project schedule and cost, and assist in technical specifications and documentation for the experiment. I also provide inspection and construction management services.” – Carolyne Neron, Project Manager

Marie Vidal

 

“I am a PHD student under the supervision of Ryan Martin and Gilles Gerbier. My thesis is about the coherent neutrino scattering. I will mostly work on simulations and designing of the experiment using the NEWS-G SPCs to look for low energy neutrinos from nuclear reactors.”  Marie Vidal, PhD candidate

.

Jacob Morrison

“My name is Jacob Morrison and I am working with the NEWS-G research group for the coming year as a junior research engineer.  My main focus will be streamlining the electronics and data analysis software incorporated in the group’s spherical gaseous detectors with the hopes of combining it all into one compact device and applying this device to a translucent spherical gaseous detector for outreach purposes.  I recently graduated with a Bachelors of Applied Science in Engineering Physics from Queen’s University and have already worked with the NEWS-G research group for approximately a year, both as a summer student and in conjunction with my senior thesis.”Jacob Morrison, Engineer

Firsts Results from the NEWS-G direct dark matter search experiment at the LSM

The NEWS-G experiment reports the first results from the search for low-mass WIMPs with SEDINE, a 60cm diameter Spherical Proportional Counter (SPC) prototype operated at the Modane Underground Laboratory (LSM). Competitive constraints were obtained on the spin-independent WIMP-nucleon interaction cross section in the GeV mass range and the most stringent limit ever reported worldwide was set for WIMP masses below 0.6 GeV. Not only do these results confirm the high potential of the novel detection technique of SPCs for light dark matter searches, they are extremely promising for the next phase of the experiment at SNOLAB.

The manuscript is available on the Arxiv (arXiv:1706.04934) and has been submitted to the Astroparticle Physics Journal. (edit: The paper has been published in January 2018.)
