<p>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.</p> <p>I was going to explore the effect of the thresholds on the pulser peak.</p> <p>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 is such a high energy i don't quite understand what is happening in the ASIC.</p> <p>I thought i would share it with you.</p> <p>PB-5 input to 50R is 10v with no attenuation. Signal height on the inline 'scope is +5.2v</p> <p>ASICs are set to "default" with 1GeV range and 3uS shaping time.</p> <p>Let me know if anything useful can be gleaned by more tests on LYCCA.</p>
