Department №40

Introductory lecture

Experiments in high energy physics on lhc as an example


Main purpose of the introductory lecture is to introduce students to the modern tendencies of accelerator experiments, to physical problems they solve and also give an idea of the detectors and their purpose.

Each of the existing or planned accelerators and experiments have their own features and can use various technologies. However basic purpose of the main units is usually the same. Thus the review will basically deal with Large Hadron Collider and ATLAS experiment, where MEPhI department 40 workgroup is involved. Lecture will be focused on the issues important for the following laboratory works.


  • Modern trends in the high-energy physics experiments
  • Large Hadron Collider, its structure, operation principles, beams structure, timing, luminosity
  • Physics problems of the LHC in proton-proton and ion-ion collisions
  • 4 experiments at the LHC and their purposes
  • ATLAS experiment: structure, detectors, triggers, particle identification, radiation occupancy, the problem areas and requirements for the sLHC
  • TRT detector: short history of development, structure, operation principles, electron identification
