In this work, we investigate the detection properties of existing prototypes of BJT detectors operated with floating base. We report about results of two functional tests. The charge-collection properties of BJT detectors were evaluated by means of a pulsed laser setup. The response to alpha-particles emitted from radioactive (241)Am source are also presented. Experimental results show that current gains of about 450 with response times in the order of 50 mu s are preserved even in this non-standard operation mode, in spite of a non-optimized structure.
