Thu Apr 30 15:28:25 2015, Patrick Coleman-Smith, High Energy Spectra from LYCCA with pulser
|
I have an eight FEE64 system now in place on the LYCCA chamber with a PB-5 pulser going into the adapter cards test input. The test capacitor is 30pF.
I was going to explore the effect of the thresholds on the pulser peak.
I notice that the spectra look like those taken in RIKEN and not a single peak. In the 1GeV range I would interpret this as noise but since this |

|
I have tried the latest version ( 26 ) of the FEE64 code and carried out some measurements of the Fast Trigger delay from the Pulser signal ( not the
Pulser Trigger out ) and observed the following.
The pulser gives a centroid of 28217 in the histogram. |

Wed Apr 29 10:01:27 2015, Patrick Coleman-Smith, Fast Trigger output fault in FEE64 FPGA logic
|
The Fast Trigger output of the FEE64 is formed from the OR of the four OR16 signals ( one from each of the ASICs.
The logic levels of the OR16 signals are active low in the FPGA and so if the are OR'd together then the output is inactive if any one of the ASICs
is inactive. |
