The origin of the soft X-rays is not clear at present.
For soft X-ray attenuation is generally considered to be significant.
They were surprised to find a distinct shadow of the soft X-rays.
However, other wavelengths (like soft x-rays) are preferred where analytical information is required.
It is logical to ask whether attenuation of soft X-rays in such a wind might account for the dividing line.
They observe in soft and hard X-rays, from 3 to 35 keV.
High voltage vacuum capacitors can generate soft X-rays even during normal operation.
The process generates a dense plasma, or ionized gas, that gives off a stream of the soft X-rays.
The technique is based on an accelerator known as a synchrotron storage ring, which can create a very bright source of soft X-rays.
Their instruments detected weak radio emissions and bursts of soft X-rays from the sunspot group.
