Hi-Res
Schematic view of how the IBIS instrument on-board INTEGRAL can detect the
radiation and derive the position of powerful gamma-ray bursts (GRB) even when
they occur outside of its field-of-view (blue shaded area). This is only
possible because the IBIS instrument has two detector layers: ISGRI with smaller
pixels (pink) and PICsIT with larger pixels (cyan) sensitive to higher energy
radiation. Gamma-rays from off-axis GRBs (yellow) can deposit some energy in the
ISGRI detector layer while being Compton scattered. The deviated gamma-ray can
then be detected a second time in the PICsIT detector. Combining the information
on the deposited energy and the position in each detector layer, it is possible
to derive the spectrum of the GRB and its position on the sky.

Artist's representation of ESA's INTEGRAL gamma-ray observatory observing the
Earth in a four-slot campaign, during a period spanning from 24 January to 9
February 2006. The main purpose of the observations has been studying the
high-energy diffuse background radiation known as 'cosmic X-ray background'
(CXB), by analysis of the drop of its isotropic flux (not varying with distance
or direction) while Earth passes in front of INTEGRAL's field of view.
High-energy emission from the atmosphere, due to reflections of the CXB,
interaction with cosmic rays and aurorae, have also been observed.

are covered by ceramic. The aluminum structure separating the eight ISGRI
modules - the ISGRI spider - is also visible.

Schematic view of the SPectrometer of INTEGRAL (SPI). The main elements of the
gamma-ray telescope are the coded mask on the top, the Germanium detector
(yellow hexagons at the bottom), and the complex anticoincidence system (ACS) to
actively shield the tube and the bottom of the telescope (red and pink
cylinders).

by stars or reflections from the spacecraft.
