Abstract: A fluid is treated by coil assembly close to the fluid. An AC power is provided to the coil assembly. Current is conducted from the AC source in a first loop including a first switch during at least a portion of a first half-cycle of the AC power source. The first switch is opened during a second half-cycle and a subroutine of producing a first ringing pulse in the coil assembly and a second and subsequent ringing pulse is performed. The second pulse may be produced after or before the preceding pulse substantially decays. An apparatus for the method includes a controller configured to close the first switch and open the second switch during the first half-cycle and to perform the subroutine of closing and then opening the second switch during the second half-cycle to produce at least one ringing pulse of current in the coil assembly.

Abstract: A method and system of generating a ringing magnetic pulse for the treatment of flowing liquids include's a coil and an SCR coupled in series with the coil to form a first loop. An electronic switch is coupled in series with the coil to form a second loop. An AC voltage signal is applied to the coil having first and second half-cycles. Current is conducted through the first loop during the first half-cycle when the SCR is forward biased while preventing current from conducting through the second loop. Current is conducted through the second loop during a portion of the second half-cycle while current is prevented from conducting through the first loop. Current is interrupted through the second loop during another portion of the second half-cycle upon the coil current reaching a predetermined value to interrupt current flowing through the coil, thereby generating a ringing magnetic pulse.

Abstract: A crystal growth setup within a physical vapor transport growth furnace system for producing AlN monocrystal boules at high temperatures includes a crucible effective to contain an AlN source material and a growing AlN crystal boule. This crucible has a thin wall thickness in at least that portion housing the growing AlN crystal boule. Other components include a susceptor, in case of an inductive heating, or a heater, in case of a resistive heating, a thermal insulation enclosing the susceptor or heater effective to provide a thermal gradient inside the crucible in the range of 5-100° C./cm and a furnace chamber capable of being operated from a vacuum (<0.1 torr) to a gas pressure of at least 4000 torr through filling or flowing a nitrogen gas or a mixture of nitrogen gas and argon gas. The high temperatures contribute to a high boule growth rate and the thin wall thickness contributes to reduced imparted stress during boule removal.
