Abstract
In this work study of bulk semi-insulating (SI) InP:Fe-based particle detectors with emphasise to the role of detector volume is presented. Detectors based on three various materials with active contact area between 0.3-5.5 mm/sup 2/ and various base length, 190, 400, and 1830 /spl mu/m were fabricated and tested. Obtained attenuation volume ranges between 0.12 and 5.7 mm/sup 3/. Detection performance of detectors was tested at temperature 230 K. Charge collection efficiency and energy resolution tested using /spl gamma/-ray sources (/sup 241/Am, /sup 57/Co) are demonstrated. Problems of measurement at voltages >1 kV necessary for detectors with long base (>500 /spl mu/m) and architecture of a "large volume" radiation detector based on bulk SI InP applicable in detection of solar neutrino are discussed.
