Particle detectors

About

Lecture 5: Detector characteristics: ALEPH Experiment cut through the devices and events - Discuss the principles of the main techniques applied to particle detection ( including front-end electronics), the construction and performance of some of the devices presently in operartion and a few ideas on the future performance. Lecture 4-pt. b Following the Scintillators. Lecture 4-pt. a : Scintillators - Used for: -Timing (TOF, Trigger) - Energy Measurement (Calorimeters) - Tracking (Fibres) Basic scintillation processes- Inorganic Scintillators - Organic Scintil - Discuss the principles of the main techniques applied to particle detection ( including front-end electronics), the construction and performance of some of the devices presently in operation and a fiew ideas on future developpement session 3 - part. b Following Calorimeters lecture 3-pt. a Calorimeters - determine energy E by total absorption of charged or neutral particles - fraction of E is transformed into measurable quantities - try to acheive signal and E - radiation lengh - nuclear absorption lenght session 2 - part. b - following of the second part of the detector Session 2 - part a. - second part of the detector: performance of tracking detectors - What happens to the electrons Session 1 - part b. Explanation about the way of calibrating with UV Lasers Session 1 - part a. - Introduction - Colorimeters - Others Techniques; TOK, CHER, TRD - Comments about futur - Discuss Physics principles of major detection techniques - Understand limitations ( incl. those of front-end electronics - Discuss performance of few current experiments - Look at future requirements (LHC/SSC) and a few ideas - Add tables + Fig. for those interested in further details. Limitations - Concentrate on Det. for Colliders ( i.g. more complicated; + a good example) - Leave out: other very interesting applic.: nuclear ph. , Astronomy, Biology... - Leave out: technical info. on construction materials+ procedures We shall discuss the…
