Pixel Detector
Determines:• Impact parameter
resolution• Ability of the Inner
Detector to find short- lived particles such as B hadrons

Transition Radiation Tracker (TRT)
Assists in electron identificationUses a system which includes Xenon gas and “straws” • Each straw is 4 mm in diameter and equipped
with a 30 μm diameter gold-plated W-Re wire. • The maximum straw length is 144 cm in the
barrel, which contains about 50 000 straws.• Endcaps contain about 320,000 radial straws.

ATLAS
ATLAS:• Is 45 meters long. • Is more than 25 meters high.• Weighs about 7,000 tons. Is half as big as the Notre Dame Cathedral in Paris. Weighs the same as the Eiffel Tower.

ATLAS vs. LHC
LHC:• Lies in a tunnel
27 kilometers (17 miles) in circumference.
• Is 175 meters (574 ft.) beneath the Franco-Swiss border.
• Workers include over 10,000 scientists and engineers from over 100 countries.
