In general, larger detectors have higher efficiency than smaller detectors, although the shielding properties of the detector material are also important factors.
A large, well-experienced international collaboration from Canadian and US universities and laboratories are jointly working toward a large tonne-scale detector.
The largest such detector is the water-filled Super-Kamiokande.
LIGO thus became the first large detector in what scientists hope will be an international network of similar instruments on the ground and eventually in space.
ATLAS is the largest detector ever built at a particle collider .
(We are, in any case, unlikely to be able to build a larger detector!)
The observatory's four large detectors are designed to be 10 to 20 times more sensitive than any previous gamma-ray instruments.
There are proposals to build a detector ten times larger than Super Kamiokande, and this project is known by the name Hyper-Kamiokande.
Dark matter particles could accumulate in the Sun or Earth and annihilate, producing neutrinos observable in large underground detectors.
The other particles that are created in the interaction are tracked by large detectors to reconstruct the physics of the interaction.
