AIDA Student Tutorial - GASEOUS DETECTORS IN HEP

Tuesday 9 Apr 2013, 12:30 → 18:30 Europe/Zurich

Touschek Auditorium (LNF)

On the day before the AIDA Annual meeting a special tutorial session on Gaseous Detectors in HEP is offered. The session takes place on the afternoon of April 9th 2013 at Laboratori Nazionali di Frascati (INFN), Touschek Auditorium.

Some rooms for students are reserved at LNF Hostel. LNF will book rooms on student’s request. Please contact Local Organising Committee

Please register if you like to participate in the tutorial session. Participation is free of charge but limited to registered persons.
Limited support for participation is available on a first come first serve basis. Please contact us for more details.


The Student Tutorial is partially supported by LNF Seminars Committee.

Programme:

- Signal formation in detectors (Werner Riegler - CERN)
- Simulation of gas detectors and related physical processes (Rob Veenhof - CERN)
- Front end electronics (Flavio Loddo - INFN Bari)

12:30 → 13:30 Registration

13:30 → 14:30 Lunch Break

14:30 → 15:40 Simulation of gas detectors and related physical processes

In this lecture, we go through the basic physics processes that occur in gas-based detectors. When charged particles traverse a gas, they leave behind a trace of ionisation electrons, as well as ions and excited atoms and molecules. The electrons are attracted to the anodes and, while moving through the gas, are subject to a multitude of processes: elastic and various kinds of inelastic collisions, attachment, formation of excited states and ionisation. Currently, of order 100 different processes are taken into account in an average simulation.The movement of the charges in the detector is used as basis for read-out, as discussed in the second lecture.

Speaker: Dr Rob VEENHOF (Uludag University - RD51 Collaboration)

15:40 → 16:50 Signal formation in detectors

A large variety of different detector technologies are used in present particle physics experiments. The basic principle of signal formation, namely the induction of currents on metallic electrodes by moving charges, is however common to most of these detectors types. We will review the basic theorems of signal formation in particle detectors and will apply them to a few classic detector geometries.

Speaker: Werner Riegler (CERN)

16:50 → 17:20 Coffee Break

17:20 → 18:30 Front end electronics

Front‐end electronics are one of the most important components in a particle detector system. Their main purpose is to amplify the small detector signal trying to maximize the Signal‐to‐Noise ratio and, sometimes, to perform some basic processing like energy and time measurement, digitization and storage, according to the specific application. After an introduction to some basic noise principles, a general overview of the most common front‐end schemes will be shown together with some examples and future perspectives.

Speaker: Flavio Loddo (INFN-BARI)
