> Tested performance of DAQ with following equipment > > Hamamatsu photodiode (S3590-09) > - Powered by Farnell power supply (E30/1). Bias 14V / leakage current < 10uA. > Cooknell preamplifier > - Powered by Farnell power supply (L30BT) @ 24V. > > Self-triggering of the CAEN modules is not yet working. Currently triggering using analogue electronic chain. > > Preamp signal is split. One half is sent to Ortec 747 TFA ( coarse gain = 1x / fine gain = 2 / int = 50ns / diff = > 500ns / non-inv input) -> Octal CFD CF8000 ( threshold ?? ) -> LeCroy 688AL level adapter (for NIM to TTL > conversion) -> CAEN v1730 external trigger IN > Other half is delayed by 250ns line and sent to CAEN V1730 channel 0 > > Data saved in DiodeTes/ > R1 -> Forgot bias to the diode > R2 -> Bias on. Overnight run > R3 -> Bias on. Short run to commission analysis program
