Dr Ibrahim Kesgin (Argonne National Laboratory)29/06/2015, 14:00CEC-06 - Superconducting Magnet SystemsPoster PresentationUndulators are very important insertion devices for storage ring and free electron laser based light sources to produce high-brilliance hard X-ray photon beams. NbTi based superconductive undulators (SCUs) have been recently developed and shown to reach higher on-axis peak fields compared to the field values achieved with conventional undulators. However, cooling NbTi coils to 4.2 K requires...Go to contribution page

Maxim Marchevsky (Lawrence Berkeley National Laboratory)29/06/2015, 14:00CEC-02 - Large-Scale Systems, Facilities, and TestingPoster PresentationTesting of high-field superconducting accelerator magnets aims at identifying potential causes of quenching, localizing quench origins and measuring quench propagation velocity along the coil winding. This information is essential for establishing protection limits and providing useful feedback to the magnet designers. Traditionally, quench studies are conducted using voltage taps. However,...Go to contribution page

Mr Renzhong Piao (Graduate School of Engineering, Chiba University)29/06/2015, 14:00CEC-06 - Superconducting Magnet SystemsPoster PresentationWe have started a project to develop a high field compact NMR magnet using high-temperature superconducting (HTS) inner coils. As a first step towards such a magnet, a LTS/REBCO NMR magnet was developed and operated at 400 MHz (9.39 T) in a previous work [1]. However, a homogeneous magnetic field required for high-resolution NMR measurements could not be obtained using conventional field...Go to contribution page

Toru Ogitsu29/06/2015, 14:00CEC-06 - Superconducting Magnet SystemsPoster PresentationThe conduction cooling superconducting magnets are now widely used in various application because of their minimum usage of helium. In the accelerator science field, they are also widely used for particle detector solenoids because they can minimize the materials needed for the magnet such that they can be more transparent against irradiated particles. For the same reason they are now used at...Go to contribution page

Vadim Kashikhin (Fermilab)29/06/2015, 14:00CEC-06 - Superconducting Magnet SystemsPoster PresentationHadron Colliders (HC) are the most powerful discovery tools in modern high energy physics. A 100 TeV scale HC with a nominal operation field of at least 15 T is being considered for the post-LHC era. The choice of a 15 T nominal field requires using the Nb3Sn technology. Practical demonstration of this field level in an accelerator-quality magnet and substantial reduction of the magnet costs...Go to contribution page

Mr Masato Nawa (Graduate School of Engineering, Chiba University)29/06/2015, 14:00CEC-06 - Superconducting Magnet SystemsPoster PresentationRecently, tensile stress tolerance of a Bi-2223 conductor has been drastically improved. Conventional Bi-2223 conductors with copper-alloy reinforcements or stainless steel reinforcements show tensile stress tolerance of ~250 MPa. The stress tolerance has been improved to 400-500 MPa with Ni-alloy reinforcements in combination with a pre-compression of Bi-2223 filaments/Ag-matrix [1]. This...Go to contribution page

Hyun Sung Kim (The Ohio State University)29/06/2015, 14:00CEC-06 - Superconducting Magnet SystemsPoster PresentationAdvancements in superconducting wire manufacturing has enabled the design and fabrication of superconducting coils for practical magnet applications. To apply superconducting wire for most commercial applications requiring many kilometers of wire, long-length characterization in coil form is important. This study discussed the transport properties of two different solenoid coil wound with long...Go to contribution page
