Fermilab scientist Alexey Burov has discovered that accelerator scientists misinterpreted a certain collection of phenomena found in intense proton beams for decades. Researchers had misidentified these beam instabilities, assigning them to particular class when, in fact, they belong to a new type of class: convective instabilities. In a paper published this year, Burov explains the problem and proposes a more effective suppression of the unwanted beam disorder.
In particle accelerators, the greater a beam’s intensity, the more opportunities there are to study particle interactions. One way to increase the intensity is to merge two beams with a technique called slip-stacking. However, when combining them, the beams’ interaction may cause instability. A Fermilab scientist has created a successful model of the fraught dynamics of two particle beams in close contact, leading to smoother sailing in this area of particle acceleration.
