Application of commercial silicon photodiodes for X-Ray diagnostics of laser-produced plasmas

The Polish commercial photodiodes BPYP35, BPYP41, BPYP44 have been used for X-ray diagnostics of laser produced plasmas. Short nanosecond pulses of soft (1-10 keV) X-ray in time-integrated as well as in time-resolved (for BPYP41) modes of operation have been registered. The paper presents experimental arrangements with single photodiodes and their arrays. Such features of the photodiodes as X-ray energy response function, dynamic range of amplitudes of pulses and temporal response are most important in this application. Results are presented of numerical evaluation of the photodiode X ray response function and a method is described for photodiode examinations in which α - particle source have been used
