Identification of an Effective Control Scheme for Z-source Inverter

This paper presents a comparative analysis of the Z-source inverter with two different control techniques namely the simple boost control and the maximum constant boost control with third harmonic injection. The Z-source inverter has the capability to buck-boost the input voltage without any intermediate boost conversion stage. It utilizes the shoot-through states effectively to boost the input...

Synchronization scheme for the KEKB accelerator

The design of the synchronization system of the KEKB accelerator is described. The synchronization system is classified into 1)fast timing and 2)software timing. The fast timing signals including rf frequency will be distributed by a optical transfer system with a phase stabilized optical fiber. The performance has been evaluated. A scheme of synchronization for multi-CPU control is proposed as...

Accelerator-Driven Neutron Source for Cargo Screening

Advanced neutron interrogation systems for screening sea-land cargo containers for shielded special nuclear materials (SNM) require a high-yield neutron source to achieve the desired detection probability, false alarm rate, and throughput. The design of an accelerator-driven neutron source is described that utilizes the D(d,n)He reaction to produce a forward directed beam of up to 8.5 MeV neutr...

Accelerator based epithermal neutron source for NCT

Nowadays neutron capture therapy looks very promising method of cancer treatment, especially for brain tumors by reason of selective damage cancer cells. Treatment effect of this method based on neutrons nuclear reaction with nuclides B, Gd. These nuclides have high cross-section of interaction with thermal neutrons. Unfortunately, thermal neutrons could enter only in near surface tissue and co...
