Module Overview

An in-depth discussion of detector instrumentation will be covered, designed to complement experiments in the Autumn semester laboratory classes. Topics will include the performance and use of preamplifiers, spectroscopy systems and multi-channel analysers (MCAs). Digital methods for data acquisition, including digital pulse processing, pulse shape discrimination and digital MCA systems. Instrumentation for scintillators and gas detectors, including the lasted developments in Si-PMT and GEM devices. The 2nd part of the module will cover digital signal processing and the role of noise in affecting detector performance, including Fano-limited noise, electronic noise and leakage current. Examples of current CMOS readout circuitry, ASIC designs and pixel detectors will be discussed.

Prerequisites/Co-requisites
None
Module Aims
This module explores the theory of operation and practical aspects of instrumentation for radiation detection, covering both traditional analogue instrumentation techniques plus the latest developments in digital pulse processing. Students will also critically evaluate the role of statistical processes in detector noise and electronic signal processing.

 

Learning Outcomes
After completing this module, the student will have acquired the following:

Module Specific Skills:
• A detailed understanding of the instrumentation chain used for the readout of semiconductor, scintillation and gas detectors
• A critical analysis of noise processes in detectors, with the influence of noise on detector performance.
• A knowledge of the functionality and system architecture of ASICs and pixel detectors at the forefront of current research.

Discipline Specific Skills:
• Technical expertise in handling radiation detectors, and applying a fundamental understanding of their operation to optimise detector performance.
• Ability to select the appropriate instrumentation chain for a given application.

Personal and Key Skills:
• Critical analysis and understanding of instrumentation and detector performance for a given experimental setup.
