Non-parametric pulsar analysis in the satellite reference frame for long duration experiments: Application to the X-gamma ray synchronization of the pulsar NP-0532 as observed by the COS-B satellite

AbstractThe paper describes a non-parametric analysis to obtain the phase histogram of a pulsar as seen in the satellite reference frame; the method requires only an approximate knowledge a priori of the pulsar period and of the position of the satellite. Results are presented on the derivation of the X-ray (2–12 keV) and gamma-ray (E>50 MeV) pulsar phase histograms relative to NP-0532 as observed by the COS-B satellite.

T&T: a new front-end time to digital electronics to study extensive air showers

AbstractA new modular multichannel front-end time to digital electronics is described. The T&T (tracking and timing) electronics is characterised by a 2 ns time resolution with multihits recording capability, no ambiguity in event pulse reconstruction, low power consumption and daisy-chain interconnecting capability. The simple design and the low cost per channel make it preferable for use in cosmic rays and EAS as well as in accelerator experiments. A description of the environmental operation and tests of the T&T electronics is presented. This electronics is used in an EAS experiment in Leeds (UK) called COVER/PLASTEX. Results on the T&T electronic performances in this experiment are also presented.

The SAX mission

AbstractSAX denotes the X-Ray Astronomy Satellite selected by the Italian National Space Plan for inclusion in the Science Programme. The purpose of SAX is to perform spectroscopic, spectral and time variability studies of celestial X-Ray sources in the energy band from 1 to 200 KeV. It is intended to continue and expand upon previous observations of such sources. The instrumentation consists of four X-Ray imaging concentrators sensitive from 1 to 10 KeV (one of them extending down to 0.1 KeV), one Gas Scintillation Proportional Counter sensitive from 3 to 120 KeV, a Sodium Iodide Scintillator Crystal in Phoswich configuration operating from 15 KeV to 200 KeV; these detectors are coaligned to a common pointing axis. Three Wide Field Cameras (2–30 KeV) with axis at 90° to that of the narrow field instruments complete the payload.The Satellite launch is foreseen for 1988, in a low altitude (500 Km), low inclination (12°) orbit.The SAX scientific programme is carried out by a Consortium of Italian Institutes, in cooperation with Institutes from Holland; a partecipation of the Space Science Department of ESA is also foreseen.
