  1. Maintenance of safety-critical systems :LBDS - MKD / MKB on LHC ABTEF - 16/05/2014

  2. MKD & MKB generators in the tunnel (Point #6) • Aim of LS1 for LBDS – MKD/MKB:refurbishment of all the MKD & MKB generators (in operation + spare) • 35 MKD  30 in the tunnel + 5 spare • 10 MKB H 8 in the tunnel + 2 spare • 14 MKB V 12 in the tunnel + 4 spare • FPS actions performed during LS1: • Disassembled all the MKD & MKB generators in the lab (867) • Checked and cleaned all the mechanical parts • Checked, cleaned and measured all the electrical and electronic components of MKD & MKB (caps, diodes, GTO,…) • HV test after generators refurbishment (tunnel) • Stored and managed all the components information & measurements (lab / tunnel) in specific databases • Managed the spare parts ABTEF - 16/05/2014

  3. MKD & MKB databases • Aim of these Databases • Individual components: • Information : store and manage all the information like #SN, trade mark, model, reference of 5200 electrical components (GTO, caps, diodes…). • FYI  MKD & MKB in the tunnel + spare = 42 ABB Stacks - 420 GTO + 28 Westcode stacks - 280 GTO + 20 Dynex stacks – 200 GTO  900 GTO to manage. • Measurements: store and manage 17.000 electrical measurements (R, C, V, I,…) performed in the lab (867). • Generators: • HV tests results: store and analyse 3.500 electrical measurements performed in the tunnel (point 6). ABTEF - 16/05/2014

  4. Aim of these Databases • Documents: • Procedures, drawings, MKD/MKB tracking files, ... • MKD / MKB spare parts: • Store and manage the MKD & MKB electrical components ABTEF - 16/05/2014 • Databases in DFS: • G:\Departments\TE\Groups\ABT\Sections\FPS\Systems\LHC\MKD_MKB & spare parts

  5. Organization of the MKD & MKB databases ABTEF - 16/05/2014
