In order to further increase the collision rate, the whole chain of accelerators that provides particle beams to the LHC needs to be upgraded.

One way to increase the luminosity is to boost the beam intensity (the number of particles in the beam). I am involved in pushing the limit of acceptable beam intensities in the LHC injector rings.

Collider (LHC [2]). For the High-Luminosity LHC (HL-LHC [3]), it will probably need to be increased up to σ [4], due to the larger bunch charge, and longer triplets resulting in the lengthening of the region where the two beams share the same vacuum beam pipe and continue to interact with each other: Θc = Θ norm c × r ǫ β∗ = Θnorm.

We present the design of a future high-energy high-luminosity electron-hadron collider at RHIC called eRHIC. We plan adding 20 (30) GeV energy recovery linacs to accelerate and to collide polarized and unpolarized electrons with ha drons in RHIC. The center-of-mass energy of eRHIC will range from 30 to by: 8.
