We analyzed RXTE data from the burst of the year 2000 of the X-ray millisecond binary pulsar SAX J 1808.4-3658 with the intent of determining the new orbital parameters.We used the observations of SAX J1808.4-3658 performed by the Rossi X-Ray Timing Explorer (RXTE) when the source was again detected in outburst during the period January-March 2000 (Wijnands et al. 2001). In particular we examined the data from the Proportional Counter Array (РСA) (Jahoda et al. 1996). We first applied barycentric correction to the data using the optical coordinates of the source (Roche et al. 98).

AbstractThe capabilities of the X-ray Timing Explorer (XTE) are described with particular attention paid to current scientific problems it will address from galactic neutron star systems to active galactic nuclei. It features a low-background continuous 2-200 keV response with large apertures (a 0.63-m2 proportional counter array and a 0.16-m2 dual rocking NaI/CsI scintillation array). Rapid response (in hours) to temporal phenomena, e.g. transients, is obtained by virtue of a scanning all-sky monitor and rapid maneuverability. XTE will carry out detailed energy-resolved studies of phenomena close to neutron stars (e.g. QPO’s) because of its sub-millisecond timing (to 10 μs), its high telemetry rates (to 256 kb/s), and the high throughput of its data system (to ≳ 2 × 105 c s−1).

Preliminary Results

A grazing incidence reflector which focuses radiation on to a proportional counter has been used to obtain X -ray pictures of the Sun in a number of relatively narrow wavelength bands below 2 nm. The design and development of the instrument is discussed together with the preliminary results from two rocket flights.

Powder Diffractometer

A new proportional counter x-ray detector with application for powder diffractometry has been developed. The new detector collects virtually the entire diffraction spectrum simultaneously with good efficiency and angular resolution. Thus, the powder spectrum of a small sample can be obtained much faster than with film or a conventional powder diffractometer. The detector read-out is digital and is interfaced to a dedicated minicomputer. A description of the detector system is discussed and preliminary results are presented.
