LST Mechanical Design Review Mechanical Installation Preparation H. James Krebs October 21, 2003 H.J. Krebs
Mechanical Installation Preparation • IR-12 will be 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 is empty • IR-2 is presently occupied with BaBar related items • Present status • 3 technical support staff now housed at IR-12 • Engineering offices are under construction • Estimated completion November 1 • Jim Krebs & Zohrab Vassilian move to IR-12 immediately after completion of this review H.J. Krebs
IR-2 H.J. Krebs
IR-12 H.J. Krebs
IR-12 Activities • Pre-installation preparation of brass plates • Radius corners • Drill & tap threaded holes for slide screws and swivel shackles • Adjust camber if necessary • 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 • FWD PEP beam line H.J. Krebs
12” Thick (Z) Sextant Prototype H.J. Krebs
Sextant Iron Cable Channel H.J. Krebs
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 • Load test • Practice brass plate installation • Brass push/pull test (see talk by Allen Constable) • LST detector installation preparation • Test installation hardware • Practice LST detector installation • A full Z length (3750mm) gap model exists for this H.J. Krebs
Full Z Length (Layer 17) Gap Model H.J. Krebs
Full Z Length (3750mm) Gap Model H.J. Krebs
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 H.J. Krebs

Conclusions and Comments • The full scale model will be a valuable tool for installation preparation • Earthquake bracing must be designed for this model • EQ committee approval approximately mid November • Construction of model shall commence end of November • All support personnel will be trained using actual hardware • Hardware will be tested to assure fit function and safe operation • Brass absorber will be prepared and staged for installation H.J.
