چکیده
The scientiic instrumentation on board the X-ray Astronomy Satellite BeppoSAX includes a Medium Energy Concentrator Spectrometer (MECS), operating in the energy range 1.3?10 keV, which consists of three units, each composed of a grazing incidence Mirror Unit and of a position sensitive Gas Scintillation Proportional Counter. The design and performance of the MECS instrument are here described, together with its on-ground calibration.

A BeppoSAX observation of the coronal X-ray emission of the active binary VY Ari
We present a study of the X-ray coronal emission from the active binary VY Ari, using data from both the Low Energy Concentrator Spectrometer (LECS) and the Medium Energy Concentrator Spectrometer (MECS) instruments onboard the X-ray satellite BeppoSAX. Using these instruments, the X-ray spectrum of VY Ari can be studied across two full decades of energy, from 0.1 to 10 keV. The spectrum is wel...

We report results of a ROSAT HighResolution Imager (HRI) observation of the X-ray error box given by the BeppoSAX Wide Field Camera for the gamma-ray burst that occurred on 1997 February 28. The observation started 10 days after the burst and ended three days later, with a total exposure of 34.3 ks. An X-ray source was detected within the 3 WFC error box and its position determined with a 10 ra...

متن کاملHow Abundant is Iron in the Core of the Perseus Cluster?
The analysis of Perseus data collected with the Medium Energy Concentrator Spectrometer (MECS) on board Beppo-SAX shows that the ratio of the flux of the 8 keV line complex (dominated by Fe Kβ emission) over the 6.8 keV line complex (dominated by Fe Kα emission) is significantly larger than predicted by standard thermal emission codes. Moreover the analysis of spatially resolved spectra shows t...
