Low-energy antiprotons with GAPS

We explored the low-energy antiproton capabilities of the GAPS detector and found that low-energy antiprotons will be measured with unprecedented statistics. GAPS has a strong capability to observe signatures of […]

Particle Physics Project Prioritization Panel (P5)

The DOE report: Building for Discovery: Strategic Plan for U.S. Particle Physics in the Global Context (pdf) concludes in regard to antideuterons: Future experiments sensitive to antideuteron fluxes at low […]

First dedicated cosmic ray antideuteron workshop

The first dedicated cosmic ray antideuteron workshop took place at ULCA in June. It brought people together from theory and experiments as well as collider and cosmic ray experiments. Slides […]

Publications of the prototype flight results

The GAPS prototype flight was a huge success and the results are published: P. von Doetinchem, T. Aramaki, N. Bando, et al. The flight of the GAPS prototype experiment ASTROPART […]

pGAPS balloon flight from Taiki

This is a time lapse movie taken with a point-and-shoot digital camera mounted to the frame of the payload during the pGAPS flight on June 3rd. 2012 in Taiki, Japan.

Launch day

The final launch preparations started at 10pm. The detectors were driven cold using the ground cooling approach with Nitrogen. During this period check-out tests with X-ray tube and atmospheric muons […]

Testing in Taiki

The experiment also survived the next trip by truck to Japan’s most northern island Hokkaido without problems. The Taiki base is in operation for balloon flights since 2008 and is […]

Thermal vacuum test

The ballooning group has a large “dirty” thermal vacuum chamber for balloon payloads. pGAPS fitted perfectly and we had a full day of testing. The goal was to mimic the […]
