S. A. Isaac Mognet is currently a research professor working in the group of Stephane Coutu. Previously he was a postdoctoral researcher and instructor at UCLA where he worked on indirect dark mater detection in the group of Rene Ong. He was a graduate student at Penn State working on the CREAM experiment with Stephane Coutu. Currently he is working on the CREAM (high energy cosmic rays), HELIX (cosmic ray isotopes), and GAPS (dark matter) experiments.

First flight of HELIX

The High Energy Light Isotope eXperiment is designed to measure various isotopes of cosmic ray nuclei, which are sensitive to the history of propagation of these energetic particles through our Milky Way galaxy, and which are linked to energetic interactions in the interstellar medium (yielding antimatter as well as rare nuclei). The instrument had its first stratospheric balloon flight on May 28, 2024 from the Esrange rocket/balloon base in northern Sweden, landing on Ellesmere Island in the Canadian high Arctic after more than 6 days. The Penn State group includes IGC faculty Stephane Coutu and Isaac Mognet, and past and present students Heather Allen, Carl Chen, Alex Pazoki and Monong Yu.
New TIGER approved for deployment to the International Space Station
2022-09-26
A team of physicists that includes researchers at Penn State is developing a new experiment envisioned for the International Space Station (ISS) as part of NASA’s Astrophysics Pioneers Program. The new experiment, the Trans-Iron Galactic Element Recorder for the International Space Station (TIGERISS), will be designed to measure the abundances of ultra-heavy galactic cosmic rays—high-energy particles that have been rapidly accelerated from a star’s violent collapse, called a supernova, or other cosmic events such as the merger of two neutron stars. By measuring the quantity of each atomic element in cosmic rays, scientists gain information about where they could have originated.
TIGERISS is an evolution of the TIGER and SuperTIGER balloon-borne instruments, developed by scientists at Washington University, NASA Goddard, Caltech and others over the past three decades, with the Penn State contingent invited to participate in the next phase of the science program. “We are excited to join old friends from the cosmic-ray ballooning community in investigating the rare but fascinating ultra-heavy cosmic rays,” said Stephane Coutu, professor of physics and of astronomy and astrophysics and the Penn State lead investigator for the TIGERISS program. “The origin of the heavy elements of the periodic table, such as the gold you might wear around your neck or finger, ultimately links back to intriguing, violent and exotic astrophysical phenomena.”
Other Penn State team members include physics research professors Samuel Isaac Mognet and Tyler Anderson. Together the Penn State team has decades of experience successfully developing detector elements for space-rated instruments flown on high-altitude balloons or to the ISS where TIGERISS will be deployed in a few years.
