Technology for production of amorphous alloys large scale cores

High average power pulsed accelerators are enabling the potential use of high peak power technology in a number of different industrial application areas such as material processing, food processing, stack gas cleanup and the destruction of organic contaminants etc. The development and commercial availability of amorphous alloys allowed the development of new class of short pulse duration, high peak current, high average power accelerator that is capable of efficient repetitive operation up to 10⁴ pps (pulses per second) using semiconductors, thyratrons and saturable core magnetic switches. The saturable switches are now employed in high current, high average power systems, such as CLIA, TBA and COBRA accelerators and others. It is known, that optimum magnetic properties of amorphous alloys for use with high dB/dt applications are achieved only with core annealing. With increasing magnetization rates there are increase interlaminar voltage and core loss (cause by interlaminar eddy currents). Ribbon for such cores have to be coated with interlaminar insulation coating. As a rule, manufacturers of large scale cores use amorphous alloys (2605SC, 2605CO or 2705 MET-GLAS^TM) without annealing, but with interlaminar insulation (mylar or special paper). With such technology core has high interlaminar break voltage, but nonoptimal magnetic properties: induction Bm, squareness ratio B_r/B_s (SR), pack factor (PF) and increased losses. The paper addresses the specialists associated with development and manufacturing efficient (low loss), most compact, inexpensive and reliable cores with inorganic insulation coating, for magnetic pulse compression circuit (MPC), magnetic switches (MS), inductors for linear accelerators (ILA), high voltage pulse transformers (HVPT), pulse power transformer (PPT) etc
