Description

This item was taken from the IEEE Periodical ' Design and Analysis of TQS01, a 90 mm$hboxNb_3hboxSn$Model Quadrupole for LHC Luminosity Upgrade Based on a Key and Bladder Assembly ' The US LHC Accelerator Research Program (LARP) is developing Nb 3Sn accelerator magnet technology for the LHC luminosity upgrade. Two 90 mm "Technology Quadrupole" models (TQS01, TQC01) are being developed in close collaboration between LBNL and FNAL, using identical coil design, but two different support structures. The TQS01 structure was developed and tested at LBNL. With this approach coils are supported by an outer aluminum shell and assembled using keys and bladders. In contrast, the second model TQC01, utilize stainless steel collars and a thick stainless steel skin. This paper describes the TQS01 model magnet, its 3D ANSYS stress analysis, and anticipated instrumentation and assembly procedure
