Syllabus

The purpose of the course is to impart knowledge and understanding of modern experimental techniques for detecting charged and neutral radiation. In particular, students will develop the practical skills and understanding necessary to conduct particle detection experiments, encompassing the design phase, implementation, data acquisition, and analysis.

Critical thinking and independent judgment will be fostered through a problem-solving approach, where students propose and discuss solutions collaboratively. This method also aims to enhance learning abilities and communication skills

Laboratorio di Acquisizione e Controllo Dati

The student will be introduced to the use of electronic instrumentation
for analogue signals treatment and data acquisition.
General concepts about trigger event logic will be treated.
A series of experiments will be designed and performed using NIM electronics and VME electronics.
Measurements of ionazing radiation will be performed and data will be collected, analyzed and discussed.

The course is aimed at learning basic experimental tecniques in use in
nuclear and subnuclear physics experiments for the detection of charged
and neutral particles.
The student will be introduced to the use of electronic instrumentation
for data acquisition such as
-NIM electronics (leading-edge, constant fraction and zero-crossing
discriminators, coincidences, Fan in-out, scalers, dual-gate, etc...)
- VME electronics (TDC, ADC, scalers, input-output registers,...)

General concept about trigger, acquisition event logic will be treated.

A series of experimental measurements will be made and data will be
collected, analyzed and discussed.

List of laboratory measurements.

-Handling, mounting and use of scintillators, light guides and
photomultiplier tubes.
-Instruments calibration.
-Signal timing and coincidences.
-Time interval distribution measurement.
-Energy measurements with charged particles and gammas.
-Measurements of the efficiency of a plastic scintillator.
-Energy resolution measurement, range and Bragg curve measurements with
alpha particles and silicon detectors.
