Mark Thomson, a Cambridge University professor of experimental particle physics, is about to take the reins as Cern's new director general. What sets his appointment apart is that it coincides with one of the most crucial moments in the LHC's life cycle - its five-year shutdown for an upgrade, which will effectively turn off the machine until the end of his tenure.
This shutdown marks a pivotal moment in Thomson's time at Cern, as he prepares to oversee the next major phase of the high-luminosity LHC project. This upgrade promises to squeeze the proton beams, making them brighter and increasing collisions tenfold. Detectors will be strengthened too, allowing scientists to better capture signs of new physics.
Thomson is well aware that this upgrade won't just revolutionize our understanding of particles but could potentially uncover answers to fundamental questions in physics - such as why elementary particles gain mass from the Higgs field or how Higgs bosons interact with each other. However, there's still much uncertainty surrounding these theories.
Beyond his role at Cern, Thomson will have a hand in navigating the future of particle physics beyond the LHC's current lifespan. This entails deciding on plans for an even more massive machine, the Future Circular Collider (FCC), which promises to surpass the LHC in size and energy capabilities.
While the engineering challenges are daunting, Cern member states must also contend with funding concerns. Since they cannot cover the full cost of the FCC alone, international collaboration will be essential to make this ambitious project a reality.
Despite these complexities, Thomson remains committed to pushing the boundaries of human knowledge about the universe's most fundamental aspects. "We've not got to the point where we have stopped making discoveries," he emphasizes, stressing that now is far from the right time to give up on further scientific exploration.
