Spheromania II


A new sphere has arrived!

LEP was a 27km circular electron-positron collider at CERN. After it was retired and dismantled in 2001, some of its 128 spherical accelerating RF cavities were refurbished into Spherical Proportional Counters. One is currently in Saclay, another is in Thessaloniki, and a third has come to Kingston after spending a few years in China. This 130cm copper sphere is similar in size to the future SNOLAB detector. It will allow us to do full size experiments, and it is already making our neighbouring labs jealous…

4th NEWS-G Collaboration Meeting in Thessaloniki, Greece – April 25-27, 2017

The fourth collaboration meeting was held by the Aristotle University of Thessaloniki in Greece where the NEWS-G team led by Ilias Savvidis is based.

About thirty collaborators from all over the world traveled to the second largest city of Greece to attend 3-days of presentations and discussions about all aspects of the experiment.

This “back-to-the-source” session (the NEWS-G collaboration originates from a 2012 symposium in Thessaloniki) led to enriching exchanges between all the participants, facilitated a full review of the current situation of the project, and resulted in decisions about the future of the collaboration, particularly concerning the upcoming detector installation at SNOLAB.

Looking forward to the next meeting, all the attendees said goodbye to each other around a traditional Greek dinner!

NEWS-G @ WNPPC, Lake Louise Winter Institute & UCLA

NEWS-G @ WNPPC, Feb 15th – 18th, 2018


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!



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
