157 – Fusion at ITER

This episode is about ITER, the international project to build an experimental fusion plant in southern France. While on vacation in that area, I had the opportunity to visit the site and talk to Richard Pitts about many aspects of the project. We focus mostly on the physics and the engineering challenges, but also address some of the organizational aspects of this huge scientific project. Note that this episode is essentially a continuation of omega tau 022 – Nuclear Fusion at MPI für Plasmaphysik; I recommend to listen to this episode first, if you haven’t done so yet.

This episode covers the discovery (strictly speaking, “strong evidence”) for high-energy (astrophysical) neutrinos. The discovery was announced on 22 November 2013. In this episode we talk with DESY‘s Markus Ackermann about the the evidence for astrophysical neutrinos and why they are important. We also discuss how the the IceCube Neutrino Observatory works, which opened up this new field of astronomy. We conclude with a brief conversation about traveling to, and living at the south pole, where IceCube is located.

This episode wraps up our recent coverage on particle physics by discussing in some detail the recent discovery of a Higgs particle. Our guest in this episode is Kerstin Borras who heads up the CMS group at DESY. We recap the role of the Higgs very briefly, look in some detail at the two detectors CMS and ATLAS, discuss the importance of the famous five sigma and look at the process by which such a discovery is confirmed and (re-)checked.

In this fourth (and for the time being, last) episode in the series on physics at CERN we look at the LHC from the perspective of the beam producers, and more specifically, from the perspective of the control system for the LHC. To this end, we first talk to Vito Baggiolini, a software engineer in the controls group, and then we talk to Felix Ehm, a technical engineer for the beam control system. In the episode we recap what the LHC does and how it does it (you may want to re-listen to Episode 30 on the LHC), discuss the hardware elements used for beam control, some of the safety and security systems, as well as about the software aspects of the system.

This episode is a conversation with CERN’s Niels Madsen about Antimatter. We first discuss theoretical aspects about the topic, and then focus on the ALPHA Experiment. Since Niels is an experimentalist and has helped building essential parts of the experiment, we discuss the experiment in some detail.

In this episode we discuss neutrinos. In the first part we talk with CERN’s Gian Giudice about the theory of neutrinos; we also discuss what it would mean if they were actually faster than light. Part two is a conversation with Edda Gschwendtner about the CERN Neutrinos to Gran Sasso experiment and the OPERA detector.

This is the first episode in a series of episodes on particle physics and related research at CERN. In this episode we are talking to John Ellis about the standard model of particle physics, which is the current “big picture” about how subatomic matter and fields work.

In this Episode, we talk about quantum computing. Our guest is Martin Laforest from the Institute for Quantum Computing at the University of Waterloo, Canada. We start with some physics basics, and then cover topics ranging from how quantum computing works, which different models of quantum computing are explored, current and future uses of the approach as well as the current state of the art. This is one of the more propellerhead-oriented episodes, so make sure you listen carefully :-)

This episode is a conversation with CERN’s Rolf Landua about the Large Hadron Collider. We start out by discussing the science and theory behind the LHC what the LHC aims to research, including the higgs boson, the standard model, super symmetry and extra dimensions. We then talked about how the LHC works (proton source, acceleration, superconducting magnets). We conclude the conversation by looking at the LHC experiments and discussing in some detail how the ATLAS detector works.
