Chopping beam to your taste

For lunch, do you enjoy having your tomato whole, in slices or finely chopped? It probably depends on the dish: The tomato could serve as a standalone fruit snack, as part of a sandwich or as a salad topping. Similarly, different Fermilab experiments may want particles beams coming to them in different chunks. Now they have a chopping “knife” to prepare the beam to their taste: the new beam chopper for the future Fermilab linear accelerator.
