  The Energy Recovery Linac (ERL) paradigm offers the promise to generate
intense electron beams of superior quality with extremely small six-dimensional
phase space for many applications in the physical sciences, materials science,
chemistry, health, information technology and security. Helmholtz-Zentrum
Berlin started in 2010 an intensive R\&D programme to address the challenges
related to the ERL as driver for future light sources by setting up the
bERLinPro (Berlin ERL Project) ERL with 50 MeV beam energy and high average
current. The project is close to reach its major milestone in 2020,
acceleration and recovery of a high brightness electron beam.
  The goal of bERLinProCamp 2019 was to discuss scientific opportunities for
bERLinPro 2020+. bERLinProCamp 2019 was held on Tue, 17.09.2019 at
Helmholtz-Zentrum Berlin, Berlin, Germany. This paper summarizes the main
themes and output of the workshop.
