Today Impedans launch the Octiv Suite. This high precision, high resolution in-line RF voltage, current and phase measurement system measures multiple fundamental frequencies and harmonics simultaneously. It reconstructs RF waveforms from complex frequency spectra and can calculate ion flux at the substrate position. Click here to find out more about this groundbreaking product.

This week Impedans are exhibiting at the 41st European Physical Society (EPS) Conference in Berlin, Germany. If you are attending, we look forward to speaking to you there.

I recently responded to a claim from Lawrenceville Plasma Physics that they were close to a commercial fusion reactor.  I was annoyed that such claims were being made and even more concerned that such claims were not receiving a strong criticism fr

The inaugural edition of the Plasma Physics Division Annual Report, from the Drexel Institute of Plasma Physics Division is available online - quoting from the release

The 9th Workshop on Frontiers in Low Temperature Plasma Diagnostics (FLTPD) was held in Zinnowitz, near Greifswald, Germany.  FLTPD is a biennial European event in which scientists working on low-temperature plasmas present their recent results, pointing out in particular the originality of the diagnostic techniques used.

I recently came across an article that described the soul as a plasma, a transitional phase between matter and energy. The essay was accompanied by the beautiful pictures of plasma globes that have become so common. There was a stage in my life/career as a physicist that this would annoy me.

Startling paper by Pete Riley on the possibility of  massive solar flare, or Carrington event happening-

Key Points

• Probability of a Carrington event occurring      over next decade is ~12%
• Space physics datasets often display a      power-law distribution
• Power-law distribution can be exploited to      predict extreme events
