A compact X-ray emission instrument is made, and the X-ray spectra are measured by changing the applied electric potential. Strong soft X-rays are observed when evacuating roughly and applying a high voltage to an insulator settled in this device. The X-ray intensity is higher as the applied voltage is increased. A light-emitting phenomenon is observed when this device emits X-rays. The present...

We present an evolutionary model for γ-ray line emission from superbubbles based on shock acceleration of metal-rich stellar ejecta. Application to the Orion OB1 association shows that γ-ray lines at the detection threshold of the SPI spectrometer aboard of INTEGRAL are expected, making this region an interesting target for studies of the interaction of supernova shocks with the interstellar me...

The average properties of the gamma ray entry region and the decay from it are studied systematically, for 49 nuclear systems, in the spin spectrometer. Preliminary results are given for the mass the neutron number dependence of the gamma ray fold distribution and of unresolved .., spectra. The possibility of gating simultaneously on narrow regions of fold and excitation energy is exploited.

The X-ray emission characteristics of a vacuum spark device operated with anode materials of various atomic numbers were studied. The temporal evolution of the X-ray emission was recorded by using five channels of high-speed PIN X-ray diodes. A time-integrated X-ray spectrometer was used to record the spectral distribution of the X-ray emission. The electron temperatures of the aluminium, coppe...

The X-ray POLarimeter (XPOL) is an instrument that will fly on-board the International X-ray Observatory (IXO). We will describe the XPOL setup in IXO and we will compare the IXO requirements with the actual prototype performance. The environmental tests performed on the XPOL prototype (thermo-vacuum, vibration and heavy ions irradiation) show that this technology is ready for a space applicati...
