HQ02a Magnet Interfaces at FNAL D.W. Cheng 3/6/2013

Introduction Guram C. provided FNAL header suspension plate details » FNAL apparently has the same basic 4- suspension rod interface that CERN uses » Therefore, HQ02a could be sent the same way as HQ01e3 was set up Additional questions are presented here HQ02a TEST AT FNAL March 6,

HQ02a TEST AT FNAL March 6, MAGNET SUSPENSION (FNAL) MAGNET SUSPENSION ADAPTER PLATE (SUPPLIED BY FNAL) Designed for 25,000 lb. capacity HQ02a is approximately ~4,500 lbs SUSPENSION RODS (CERN-type shown for pictorial only) - Actual Distance between adapter plate and pizzabox = ?? - Rod diameter = mm /.75”

HQ02a TEST AT FNAL March 6, LBL MAGNET SUSPENSION PLATE (DRAWING) Four tapped holes ¾”-16 threads, 90.0-degrees apart on ” [ mm] diameter hole pattern

HQ02a TEST AT FNAL March 6, Magnet Bottom Plate (For hanging Rohacell spacers underneath magnet) Same four ¾”-16 tapped holes as top plate can be used for hanging the foam spacer stack

HQ02a TEST AT FNAL March 6, Magnet Bottom Plate (2) (For hanging Rohacell spacers underneath magnet) Is a guide plate necessary? If so, who supplies it? Also, hardware interfaces need to be defined for hanging the Rohacell spacers

HQ02a TEST AT FNAL March 6, 2013 INSTRUMENTATION CONNECTOR MOUNTING INSTRUMENTATION CONNECTORS WILL BE LOCATED ON TO MOUNTING SKIRTS ON THE MAGNET SUSPENSION PLATE. SEARCH COIL COLD-FINGER GUIDE PLATES. 2 REQUIRED. - Guide plates must be installed before final magnet assembly at LBL. - Present guide plates can accommodate 2.50” [63.5 mm] diameter. Magnet Suspension Plate Assembly. - Supplied by LBL 9
