1 Introduction (KL) ok 2 Requirements and Overview (CB) ok 3 Linear motor (CB) – 3.1 Electromagnetic design (PS/NS) missing – 3.2 Stator (CB,PS) needs figs & refs – 3.3 Permanent magnets (CB,PS) needs figs & refs 4 Mechanical design and construction (JT) – 4.1 Target Shaft (JT) needs figs & refs – 4.2 Target Bearings (JT) needs figs & refs – 4.3 Stator (JT) see 3.2 – 4.4 Mechanical integration (CB – are people happy? ) check numbers – 4.5 Quality Assurance & Quality Control (JT, GB, PS?) magnetic missing 5 Optical position-measurement system (CB,PS) – 5.1 Optical Vane (PS,CB) needs figs & refs – 5.2 Laser Source (PS,CB) needs figs & refs – 5.3 Optical Fibres (PS,CB) needs figs & refs – 5.4 Collimators, Lenses & Mechanical Mount (PS,CB) needs figs & refs – 5.5 Optical sensors (PS,CB) brief! 6 Stator Operation & Power electronics (PS) lengthy! needs figs 7 Control, Electronics & DAQ (PS) needs figs 8 Performance (PH,AD) missing 9 Summary (CB) missing 2

Summary Most of the material is now there! CB edited some sections to improve consistency, remove history,.... More editing needed! Most lack figures and references. – (Some figs from JT – quality may be an issue.) Some sections missing: – EM Design: N Schofield contacted, agreed to provide. – Magnetic QA – PS listed, should be BS! – Performance: PH & AD In absence of EMcC I wrote “mechanical integration” section (frame, jacking system, services) – Are they adequate? Is the balance ok? Previously decided to document design of last summer. Do we wish to update? – Said would review when present version complete. 3

Next? We need the missing sections! Still inconsistencies of style (level of detail, tenses, etc.) Propose I revise text, send list of figures (& references) required. Need input! – Others’ views on amount of detail. – Are bullet-points acceptable? – Can we reference internal notes? Add summary, aim for essentially complete draft early(-ish!) in New Year. Are we agreed we leave new stator for later paper? 4
