ATLAS (link opens in a new window) is a particle physics experiment at the Large Hadron Collider (link opens in a new window) at CERN (link opens in a new window). The ATLAS detector is designed to search for new discoveries in the collisions of protons at extraordinarily high energies.
ATLAS will help us to learn about the basic forces that have shaped our universe since the beginning of time and that will determine its fate. Among the possible unknowns are the origin of mass, extra dimensions of space, microscopic black holes, and evidence for dark matter candidates in the universe.
The RAL PPD group had responsibility for the construction of the Level 1 Calorimeter Trigger, High Level Trigger and Semi-Conductor Tracker. There is also interest in the upgrades of those projects which might be required for an SLHC luminosity upgrade. (link opens in a new window)
The group currently contains 28 people, including Ph.D. students and those resident at CERN. There are multiple physics interests, including B physics, multi-parton interactions, W bosons, and Higgs searches.
