Description
Plasma wakefield acceleration offers high field gradients, typically on the order of 10 to 100x larger than conventional RF cavities. Currently available proton beams have sufficient energy to maintain these wakefields over significant distances, allowing a witness bunch of leptons to be accelerated to the energy frontier, with the plasma acting to mediate energy transfer from the proton driver to a lepton witness. The ALiVE project is pursuing the use of a sub-millimetre proton drive beam [1,2], which offers the possibility to significantly increase the beam—beam energy-transfer efficiency compared to the longer beams currently available, opening the path to collider applications. In this work, we present the potential application of ALiVE to boost LEP3 to the $t-\bar{t}$ threshold.
