We present the calibration and background model for the Proportional Counter Array on
board the Rossi X-Ray Timing Explorer. The energy calibration is systematics-limited below …

The proportional counter array (PCA) is designed to perform microsecond timing of bright
galactic sources and broad band, confusion limited, studies of faint extragalactic sources in …

The photon energy dependence of the mean energy W required to produce an electron-hole
pair in silicon for photons with energies between 50 and 1500 eV was determined from the …

Distributions of the number of primary electrons produced per incident mono-energetic x-
rays in the 1-to 41-keV energy range, which includes the xenon L-and K-absorption edges …

An experimental study of the w-values and Fano factors for Ar-Xe gaseous mixtures at
atmospheric pressures for 5.895 keV X-rays was carried out with two experimental set-ups …

X-Ray spectrometry is usually performed with one of two techniques: energy dispersive and
wavelength dispersive. Energy dispersive techniques use radiation detectors that give a …

Non-linearities in the energy response of gas detectors in the regions of the absorption
edges of the detection medium are well documented. Monte Carlo calculations show that the …

A new method is presented for deriving the Fano factor, F, and the mean energy per ion pair,
W i, in counting gases. It is based on the technique of individual counting of single ionization …

We have observed that the pulse-height distributions of X-ray events that deposit essentially
the same amount of energy in a xenon gas detector will vary according to the deexcitation …

A prototype Xe÷ 10% CH4 microstrip detector was used to study the K-edge discontinuity in
the pulse-height distribution as a function of the energy of incident X-rays. The electronics …
