Optical Diagnostics of Micro Discharge Jets

Towards Optical Partial Discharge Detection with Micro Silicon Photomultipliers

Optical detection is reliable in intrinsically characterizing partial discharges (PDs). Because of the great volume and high-level power supply of the optical devices that can satisfy the requirements in photosensitivity, optical PD detection can merely be used in laboratory studies. To promote the practical application of the optical approach in an actual power apparatus, a silicon photomultip...

What ignites optical jets ? ∗ †

The properties of radio galaxies and quasars with and without optical or X-ray jets are compared. The majority of jets from which high-frequency emission has been detected so far (13 with optical emission, 11 with X-rays, 13 with both) are associated with the most powerful radio sources at any given redshift. It is found that optical/X-ray jet sources are more strongly beamed than the average p...

Towards deeper understanding of an HiPIMS discharge by time-resolved optical plasma diagnostics

As a promising pulsed sputter deposition technique, High-Power Impulse Magnetron Sputtering (HiPIMS) required an extensive time-resolved plasma characterization. Being essentially non-intrusive, optical plasma diagnostics methods posses in particular the timeand spaceresolution(s) which normally exceed the typical needs of a typical HiPIMS geometry [1] and, therefore, can be readily applied for...

Optical Diagnostics within La3net*

The Laser Applications at Accelerators network (LA3NET) is a pan-European project that has received 4.6 M€ of funding from the European Union's 7th Framework Programme. It closely links research into lasers and accelerators to develop advanced particle sources, new accelerating schemes, and in particular beyond state-ofthe-art beam diagnostics. This contribution summarizes the research achievem...
