Hello, my name is Tsuguo Aramaki. I am an Assitant Professor at Northeastern University. Throughout my career, I have been deepening my experience and broadening my perspective to reveal the nature of dark matter. My research interests lie primarily in exploring dark matter through both direct and indirect dark matter search experiments.
Currently, I am spearheading a new project, GRAMS (Gamma-Ray and AntiMatter Survey) that I have conceptualized while continuing my tasks and duties for the dark matter search programs, SuperCDMS (Cryogenic Dark Matter Search) and GAPS (General Antiparticle Spectrometer). GRAMS can open a new window for astrophysical observation in the MeV energy domain while deeply exploring dark matter parameter space through antimatter measurements. As argon is one of the most abundant natural gases on earth, the project can cost-effectively expand from a balloon mission to a satellite mission. LINK FOR PAPER.
The SuperCDMS SNOLAB project, a DOE/NSF funded second generation direct dark matter search program, aims to measure the recoil energy induced by dark matter-nucleus scattering through phonon and ionization signals. This underground experiment can broadly cover the dark matter parameter space for a variety of viable dark matter models. SuperCDMS can also complementarily prove the parameter space with other direct dark matter search experiments as well as indirect dark matter search and collider experiments. As a level-3 manager of the SuperCDMS SNOLAB experiment, I am in charge of detector tower assembly, cold hardware/readout electronics development and testing and the detector testing. The full operation and data taking will begin in 2021/2022.
Before beginning my research at the SuperCDMS group, I was a member of the GAPS (General Antiparticle Spectrometer) mission at Columbia University for 9 years. GAPS is a balloon-borne indirect dark matter experiment that focuses on low-energy antiprotons and antideuterons produced by the dark matter co-annihilation and decay. As a founding member, I devised and designed the GAPS concept while revising the GAPS instrumental design. During my early career, I led the detector development, accelerator beam test, prototype flight and data analysis while evaluating the GAPS antiproton/antideuteron sensitivities and augmenting the scientific goals. The GAPS first science flight has been recently funded by NASA and scheduled to launch from Antarctica in 2022/2023.
