  The field of experimental particle physics studies the fundamental particles
and forces that constitute matter and radiation. Frequently the experimental
tools used to enable this study are accelerators and detectors. The Large
Hadron Collider (LHC) is the highest energy proton-proton accelerator currently
operating and where the ATLAS and CMS collaboration discovered and are
currently studying the properties of the Higgs boson. These notes provide a
short introduction to accelerators and detectors using the LHC and its
detectors as examples. The detector section will focus on two types of
detectors extensively used today: tracking detectors and calorimeters. The
notes will then discuss the algorithms used to process the information from the
detectors and how that information is used for physics analysis using the
search for the decay of the Higgs boson to bottom quarks.
