HALO – Open to All

14th November 2026, 2:00 – 5:00 pm

Step inside the extraordinary world of particle physics during Harwell Campus’ 80th year.

OPEN TO EVERYONE

This November, Harwell welcomes HALO, a large-scale immersive artwork by artist duo Semiconductor. It turns real particle collision data from CERN into light, sound and movement.

A collision of light, sound and science

Step inside HALO’s vast cylindrical structure and become surrounded by a 360-degree projection. As patterns emerge across the screen, the same scientific data triggers 384 vertical wires, turning the installation into an immense musical instrument.

Collisions that happen in fractions of a second are slowed down, revealing movements and patterns usually hidden from view. The result is a powerful encounter with the experiments helping scientists understand the building blocks of our universe.

Key details:

  • Date: Saturday 14th November
  • Time: 14:00 – 17:00. Tickets are available with entry on the hour.
  • Tickets: £2 (Ages 5+) Under 5s go free, no ticket required.
  • Location: Tech Foundry 3, Harwell Campus, OX11 0GD (Google Maps here)

All ticket proceeds for this event go to support ATOM Festival of Science and Technology in Abingdon. You’ll be taken to the ATOM Festival ticketing page to complete your booking.

Car Parking: Free parking is available directly outside the venue. There is no EV charging available to visitors on campus.

We’re planning an exciting programme of events for different audiences at HALO – keep an eye out for further announcements.
