      Welcome and general introduction
      - Parameter summary (beam and laser) - Layout building situation and environment parmeters - Layout machine lattice at the LH (overview of all components + 2D model - Integration of laser transfer in the building - Illustration aspects (task distribution overview) - Scheduling and comissioning aspects
      Speaker: Marco Pedrozzi (Paul Scherrer Institut)

      LH specifications and beam dynamics
      - Beam heating requirements - Operation range (max-min charge, max-min energy) - Undulator requirements - Optics and chicane specifications (dipoles, axis separation, R56)
      Speaker: Marco Pedrozzi (Paul Scherrer Institut)
      Slides

      "Standard" Electron diagnostics
      - Screen monitors specifications & options (interfacing with photon diagnostics) - BPM (alignment survey along the undulator and feed back) - BAM (synchronization survey and feed back)
      Speaker: Rasmus Ischebeck (Paul Scherrer Institut)

      Laser system and transfer line
      - Presentation laser system and transfer line specifications/concept - Presentation laser optics & concept for the coupling (geometry & chamber constraints)

      Laser diagnostic requirements
      Suggestion: - one presentation from PSI - one presentation from our Swedish colleagues, concepts and design based on previous experience + discussion To be covered here: - Standard laser diagnostics - Energy - Alignment/pointing survey (virtual waist image) Overlap diagnostics - Transverse overlap setting (screens) + monitoring and feed back (pointing survey with 4 quadrant diodes or camera?) - Longitudinal overlap rough and fine adjustment(the most critical aspects? Survey options: BAM+LAM, EOM for survey?)). - Support system laser optics and diagnostics (optical tables, protection box,..) - Discussion about task distribution & Role of Lund University.
      Speakers: Carlo Vicario (Paul Scherrer Institut), Dr Volker Ziemann (Upsala University)

      Vacuum system
      - presentation or included in point 1)? (L. Schulz) - Presentation of vacuum chamber basic concept (motorization requirements, laser coupling, chamber size,...)
      Speaker: Lothar Schulz (Paul Scherrer Institut)
