Large-area Si(Li) Detectors for X-ray Spectrometry and Particle Tracking for the GAPS Experiment
Field Rogers, Mengjiao Xiao, Kerstin Perez +15
Large-area lithium-drifted silicon (Si(Li)) detectors, operable 150°C above liquid nitrogen temperature, have been developed for the General Antiparticle Spectrometer (GAPS) ballo…
New Particle Identification Approach with Convolutional Neural Networks in GAPS
Masahiro Yamatani, Yusuke Nakagami, Hideyuki Fuke +4
The General Antiparticle Spectrometer (GAPS) is a balloon-borne experiment that aims to measure low-energy cosmic-ray antiparticles. GAPS has developed a new antiparticle identific…
Astro 2020 Science White Paper: Cosmic-ray Antinuclei as Messengers for Dark Matter
Kerstin Perez, Philip von Doetinchem, Tsuguo Aramaki +8
The origin of dark matter is a driving question of modern physics. Low-energy antideuterons provide a "smoking gun" signature of dark matter annihilation or decay, essentially free…
Thermal Control System to Easily Cool the GAPS Balloon-borne Instrument on the Ground
Hideyuki Fuke, Shun Okazaki, Akiko Kawachi +6
This study developed a novel thermal control system to cool detectors of the General AntiParticle Spectrometer (GAPS) before its flights. GAPS is a balloon-borne cosmic-ray observa…
Large-area Si(Li) detectors for X-ray spectrometry and particle tracking in the GAPS experiment
Field Rogers, Mengjiao Xiao, Kerstin M. Perez +14
The first lithium-drifted silicon (Si(Li)) detectors to satisfy the unique geometric, performance, and cost requirements of the General Antiparticle Spectrometer (GAPS) experiment…
Application of Machine Learning to the Particle Identification of GAPS
Takuya Wada, Hideyuki Fuke, Yuki Shimizu +1
GAPS is an international balloon-borne project that contributes to solving the dark-matter mystery through a highly sensitive survey of cosmic-ray antiparticles, especially undisco…
