Workshops are regularly organised at CERN on advanced topics directly connected to the openlab projects. Most of these workshops have a special feature: they involve a mix of lecturers from both industry and CERN, thus exemplifying the CERN openlab principle of two-way knowledge transfer through active collaboration. Several of the workshops combine hands-off theory with hands-on practice. Special courses for advanced CERN users are also organised in addition to the regular quarterly courses.
