It evolved over time till the magnet was built and tested in 2006. Successful demonstration of an out of box magnet like DCC017 is a testimony to the excellent team of technicians, engineers, and scientists, supported by the management.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/wpw.bnl.gov\/rgupta\/common-coil-design\/\"><strong>Also see the Common Coil Design Explained<\/strong><\/a><\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"480\" height=\"410\" src=\"https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-31.png\" alt=\"\" class=\"wp-image-7954\" style=\"width:480px;height:auto\" srcset=\"https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-31.png 480w, https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-31-300x256.png 300w\" sizes=\"auto, (max-width: 480px) 100vw, 480px\" \/><\/figure>\n<\/div>\n\n\n<p>The common coil design was inspired by the potential of High Temperature Superconductors (HTS) in accelerator magnets. It is a modular design primarily consisting of simple racetrack coils. A new module can be added or replaced to carry out a proof-of-principle demonstration of a new idea or technology. This is an alternative to building a whole new magnet which is order of more magnitude more expensive and takes several years to build and test. The picture below shows how one or a set of coils could be inserted to become part of the magnet without requiring disassembly and reassembly of DCC017.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"311\" height=\"269\" src=\"https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-32.png\" alt=\"\" class=\"wp-image-7955\" srcset=\"https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-32.png 311w, https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-32-300x259.png 300w\" sizes=\"auto, (max-width: 311px) 100vw, 311px\" \/><\/figure>\n<\/div>\n\n\n<p>Providing a clear open space in the design required a large unsupported vertical coil module. There were many concerns for such a design, such as the coil module buckling, etc. The concept relies on the Lorentz forces pushing the main and insert coils towards the structure.<\/p>\n\n\n\n<p>DCC017 reached its computed short sample in 2006. Demonstration and effective commissioning of DCC017 as a low-cost, rapid turn-around facility was carried out under an SBIR with Particle Beam Lasers, Inc. (PBL) in 2017, when a record 8.7 Tesla HTS\/LTS hybrid dipole field was also achieved. This led to the funding of several other proposals from a variety of sources.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"269\" height=\"269\" src=\"https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-33.png\" alt=\"\" class=\"wp-image-7956\" srcset=\"https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-33.png 269w, https:\/\/wpw.bnl.gov\/rgupta\/wp-content\/uploads\/sites\/9\/2024\/03\/image-33-150x150.png 150w\" sizes=\"auto, (max-width: 269px) 100vw, 269px\" \/><\/figure>\n<\/div>\n\n\n<p>HTS insert coil test under US Magnet Development Program (MDP) in 2020 demonstrated a vast potential of this unique magnet when four samples\/coils were tested in one go.
