Speaker: Professor Peter Hobson
The Large Hadron Collider is currently operating at CERN and the four experiments that operate at it are producing exciting results which we hope will enhance our understanding of the universe just after the “Big Bang”. Experiments in High Energy Particle Physics (HEPP) often make use of the latest technology in both sensors and data processing. However sometimes old technologies, some long abandoned in both HEPP and other scientific disciplines, make an unexpected comeback. In this talk I will outline a few examples of these Lazarus-like returns, in sensor technologies such as photodetectors, scintillators and even the bubble-chamber. Most examples will be taken from experiments that I have contributed to and I will also discuss briefly the issue of when we might be able to say that a technology has really reached the end of its useful life.
