Detectors Flashcards
1
Q
4 Parts of an Onion Like Detector
A
- Tracker
- Electromagnetic Calorimeter (ECal)
- Hadronic Calorimeter (HCal)
- Muon Detector
2
Q
Tracker
A
- Detects and Reconstructs trajectories of charged particles
- Exists in a magnetic field to measure momentums
3
Q
Electromagnetic Calorimeters (ECal)
A
- e are stopped by ECal and undergo Bremsstrahlung Radiation (Emit photon and slow down)
- γ are stopped by ECal and undergo pair production (Turn into electron-positron pair)
- Probability of e/γ travelling x distance through an ECal = P = e^(-x/X)
- X is Radiation Length
4
Q
Hadronic Calorimeter (HCal)
A
- Contains all Hadronic Showers
- Probability of a hadron travelling x distance through HCal = P = e^(-x/λ)
- λ is the Nuclear Interaction Length
- Thicker than ECal
5
Q
Muon Detector
A
Detects Muons
6

8
Q
Order of Detection Path for a Electron/Positron
A
