DESCRIPTION:Have you ever wondered what a balloon-borne particle detector\,
  floating 40 km above the Earth\, can reveal about our Galaxy?\n\nJoin us 
 on Thursday\, October 9th\, 2025\, from 7:00 PM to 8:30 PM for the first T
 SI & Physics Public Talk of the academic year: “The Flight of the HELIX – 
 Measuring the Galaxy from 40 km Above Greenland”\, presented by Professor 
 David Hanna at 51�Թ���.\n\nAbout the Talk: The High-Energy Light
  Isotope eXperiment (HELIX) is a balloon-borne particle detector designed 
 to measure the flux of cosmic rays confined to the Milky Way Galaxy by its
  magnetic field. Its main goal is to determine the abundance ratio of unst
 able ¹⁰Be to stable ⁹Be\, thereby helping scientists to probe the size and
  shape of our Galaxy’s magnetic field. To carry out this task requires lif
 ting a two-tonne spectrometer\, based on a superconducting magnet\, to the
  edge of space using a giant helium-filled balloon. \n\nIn this talk\, Pro
 fessor David Hanna will provide an introduction to cosmic rays and their h
 istory\, followed by a description of the HELIX payload including explanat
 ions of the technologies underlying its different components. Much of the 
 presentation will focus on HELIX's first flight\, from Kiruna\, Sweden to 
 Ellesmere Island in Nunavut\, that took place between May 28 and June 3\, 
 2024.\n\n📅 Date: Thursday\, October 9th\, 2025\n	🕖 Time: 7:00 – 8:30 PM\n	📍 
 Location: Trottier 0100\, Trottier Building (3630 University St\, Montréal
 )\n\nCan’t make it in person? The talk will also be streamed live on TSI's
  YouTube channel! The event is free and open to everyone. Mark your calend
 ars\, we hope to see you there!\n
