GRIPS - The potential of a future MeV survey

TL;DR

GRIPS is a proposed future MeV gamma-ray mission combining imaging, polarimetry, and spectroscopy, aiming to perform a highly sensitive all-sky survey from 200 keV to 80 MeV, significantly surpassing previous missions.

Contribution

This paper introduces the GRIPS mission concept, highlighting its innovative combination of instruments and its potential to greatly improve sensitivity in the MeV gamma-ray range.

Findings

GRIPS would achieve 40 times better sensitivity than previous missions.

It would perform continuous all-sky surveys in the 200 keV to 80 MeV range.

The mission combines Compton and pair telescopes for comprehensive gamma-ray observations.

Abstract

We describe the potential of GRIPS, a future MeV mission. The Gamma-Ray Imaging, Polarimetry and Spectroscopy ("GRIPS") concept combines a Compton and pair telescope, and will be a very sensitive polarimeter. GRIPS would perform a continuously scanning all-sky survey from 200 keV to 80 MeV achieving a sensitivity which is better by a factor of 40 compared to the previous missions in this energy range.
