In this paper the authors present experimental results of X-ray spectroscopy performed with a small area (1 mm[sup 2]) silicon planar diode detector, operating at room and low (223 K) temperature. An ultra low noise preamplifier of new conception The Forward Bias FET Charge Amplifier'' is used with a commercial input JFET. These small area diodes detectors are suitable for X-ray imaging as the core of multichannel detectors, which are of great interest in many field of research and applications. The best performances in high resolution room temperature X-ray imaging are presently obtained with silicon CCD detectors, which on the contrary require an advanced technology to be produced and can work at relatively low count rate. In Section 2 the theoretical predictions of the resolution achievable with planar silicon diode detectors are shortly reviewed, in Section 3 the detector, the electronics and their assembly are described, in Section 4 the experimental results and the data analysis are presented and compared with the theoretical prediction.
