Abstract :
We have designed and implemented an UWPE (ultra-weak photon emission) measurement system - a dark chamber and low dark count PMT module - oriented to environmental control studies. The system is totally controlled by software - power supply, counting board, temperature control and shutter for light excitation. The system´s architecture and performance are described here. In terms of SNR the proposed system has presented a great improvement related to previous development, also in terms of resources provided as full automatic control of power supply, sample illumination and temperature control capability yet having low implementation costs.
