  1. LST Installation Readiness Review Mechanical Installation Preparation H. James Krebs May 5, 2004 H.J. Krebs

  2. Mechanical Installation Preparation • IR-12 is the location of most mechanical preparation work during 2004 & 2005 • Why IR-12? • IR-12 Hall is very similar to IR-2 Hall • Same floor plan • Identical 50/10 ton crane combination • We need space • IR-12 was empty • IR-2 is presently occupied with BaBar related items H.J. Krebs

  3. IR-2 H.J. Krebs

  4. IR-12 - Before H.J. Krebs

  5. IR-12 Today H.J. Krebs

  6. IR-12 Activities • Pre-installation preparation of brass plates • Radius corners • Drill & tap threaded holes for slide swivel shackles • Camber plates as needed • Stage plates for assembly • BaBar model • Build a fairly crude but full scale mock-up of the forward end of BaBar including: • Barrel assembly simulating corner blocks removed • FWD end doors • FWD PEP pier H.J. Krebs

  7. Full Scale BaBar Model H.J. Krebs

  8. 12” Thick (Z) Sextant Prototype H.J. Krebs

  9. Sextant Iron Cable Channel H.J. Krebs

  10. IR-12 Activities • Purpose of Model • Construct elevator platform • Test function • Check for interferences with end doors, beamline and PEP pier • Load test • Modify as necessary for corrections or improvements • Brass installation preparation • Test installation hardware • Practice brass plate installation • Brass push test • LST detector installation preparation • Test installation hardware • Practice LST detector installation • A full length XZ gap (layer 8) model is being constructed for this H.J. Krebs

  11. IR-12 Activities • Steel handling fixtures • Train technical support staff • Check centers of gravity • Determine appropriate rigging • Load test • Function test, if possible • Modify as needed • Perform a field job hazards analysis H.J. Krebs

  12. Elevator Platform • Due to SLAC internal problems, the purchase req for the elevator platform was issued two months later than planned. • Expect upper elevator components beginning of June • Expect lower elevator components mid June • Still enough time to erect, test and modify these platforms • Very little schedule float remains on these items H.J. Krebs

  13. RPC Pulling Clamps H.J. Krebs
