Description
The goal of this mini-workshop is to address the most important luminosity limitations at SuperKEKB (and possible consequences for FCC-ee), in particular the following four: (1) Poor specific luminosity; (2) Large emittance blow up in the transfer line; (3) Sudden beam loss; (4) Reduced injection efficiency at high current.
