FBNML正在设计并将制造一个径向冷却的插入式磁体，以产生系统Hybrid V的70%的磁场，在32 mm孔中超过45 T。插入物的总直径和最大有效线圈长度为610 mm。背景场为14 T时，系统应在24 MW时产生47 T，在32 MW时产生近49 T。峰值应力极高，需要强度高达1100 MPa的Be-Cu（UNS C17510）和24% Ag-Cu等导体。峰值热通量密度也很高，接近12 W/mm/sup 2/。因为水是最冷的，它的速度最高，热通量最高，然而，峰值温度只有80/spl摄氏度。在27个大气压下，水流量为/spl ap/200 l/s。该系统是非常用户友好。顶部的入口完全畅通无阻。插入件移除后，管道和电气连接完好无损。巨大而昂贵的外部线圈应该是长寿命的，内部线圈很容易更换。在内部线圈烧毁期间，套管拦截从内部线圈到中间线圈的电弧，从而降低烧毁严重性和故障负载。插入物应该是FBNML的世界纪录保持系统Hybrids II和III的有价值的继承者。>
The FBNML is designing and will fabricate a radially-cooled insert magnet to generate 70% of the field of a system, Hybrid V, to surpass 45 T in a 32 mm bore. The insert is to have an overall diameter and a maximum active coil length of 610 mm. With a background field of 14 T the system should generate 47 T at 24 MW and nearly 49 T at 32 MW. The peak stress is extremely high, calling for conductors such as Be-Cu (UNS C17510) and 24% Ag-Cu with strengths up to 1100 MPa. The peak heat flux density also is high, nearly 12 W/mm/sup 2/. Because the water is coldest and its velocity highest where the heat flux is highest, however, the peak temperature is only 80/spl deg/C. The water flow is /spl ap/200 l/s at 27 atm. The system is to be very user friendly. Access is completely unobstructed at the top. Insert removal leaves the plumbing and electrical connections intact. The massive and expensive outer coils should be long lived, the inner coil easily replaceable. During an inner coil burnout, a sleeve intercepts arcing from the inner coil to the middle one, reducing burnout severity and fault loads. The insert should be a worthy successor to those of the FBNML's world-record holding systems, Hybrids II and III. >
