In the latest episode of MegaVolts we talk about fusion and when it fails. It’s a grey area – sometimes colliding nuclei miss, sometimes they bounce and sometimes they stick for a little while, dance around each other and then go their separate ways, both somehow changed forever… Getting...

The challenge with detecting dark matter is that the signal will probably be incredibly small – perhaps only a couple of particles per day. So it would be really easy to be fooled by some other signal, such as lead-210, which is radioactive. Dr Anton Wallner is testing the crystals that will be used...

Episode 4 of Megavolts finds us in the HIAF experimental hall looking for dark matter with Dr Lindsey Bignell.   Actually, it’s a practice run, using neutrons instead: dark matter detections are likely to be so rare that we need to have the detectors well and truly tested before we begin live...

This is the first of the Megavolts series of videos, from the Accelerator Control Room. In this episode Dr Phil Dooley speaks with Dr Annette Berriman about the experiments going on at that moment – smashing lithium-7 into a gold target. The discussion ranges from how lithium is a weird shape,...
