Since 2004, the Burst Alert Telescope (BAT) aboard Swift has been mapping the sky using hard X-rays.
At the same time, a concerted effort would be made to develop in Canada, a general-purpose, multi-beam line SR facility with state-of-the-art performance at lower energies (below 10 keV perhaps) and some lower flux capability on the hard X-ray.
The hard X-rays found in these discoveries are supposed to come ultimately from processes of nuclear fusion and nuclear decay that between them make the heavier chemical elements.
Approximately 50 user projects have been able to take advantage of the facility so far, and the recent completion of the hard x-ray nanoprobe beamline this summer and the installation of a Beowulf-class supercomputer array with 12 teraflop capacity for computational and experimental nanoscience is expected to engender more interest in the CNM's facilities.
The Hard X-ray Nanoprobe will provide x-ray characterization at a spatial resolution of 30nm which substantially exceeds the optical limit," said Dr.
Richard Schwartz, also of ST Systems, notes that between March 6 and 19 -- the time required for the active region to cross the sun -- the satellite's Hard X-Ray Burst Spectrometer recorded 447 hard X-ray flares, a rate of about 32 per day.
of Dortmund, Germany) focuses on the scattering of hard X-rays because it has provided the bulk of information on electronic excitations and is free of the disturbing surface effects of soft X-ray investigations.
Now, scientists report the highest-resolution scanning X-ray image ever made with hard X-rays.
While the original mode yielded mainly hard X-rays, the Sandia scientists recently modified the device to work by a second process, known as "gas puff z-pinch," which generates soft X-rays.
This will open the door to additional applications of CCD-based semiconductor detectors of hard x-rays in medical diagnostics and industrial nondestructive testing imaging applications as well," Cox said.
