Today they're doing 90m optics so what exactly is this?

As far as I know it's investigating of ellastic collisions between protons for TOTEM experiment.

What K said.



" This article discusses the physics programme of the TOTEM experiment at the LHC. A new
special beam optics with β∗= 90 m, enabling the measurements of the total cross-section,
elastic pp scattering and diffractive phenomena already at early LHC runs, is explained."
