Currently, superconducting RF (SRF) systems for high-current storage rings are generally limited to low-frequency, moderate voltage, and single-cell cavities. For a new class of cavities to be used in ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition rate. It is a mode-locked laser which uses light traveling within a ...

In this brief, an online relay autotuning scheme for parameter estimation of a class of time delayed systems is presented. The identification method comprises a relay and a proportional-derivative (PD ...

Abstract Recent research on structural dynamics has steered towards elastic metamaterials, as band gap phenomena can be explored to mitigate vibration. A challenge in their design is the determination ...
