Default Setting is Excellence

My Default Setting is Excellence, what's yours?

I'm getting slightly frustrated how little is expected out of me.  Don't complicate me unless I deserve it.

On a somewhat releated note, check out our discrimination ratios.  The first is the spectrum that we get.  In order to be a good SNM (Special Nuclear Material) detector it needs to be able to detect 1 in 1000 neutrons emitted from the source (which can be quite hard, since the source would emit them isotropically - think of the solid angle)


The second shows the count rate per source neutron, we are only a factor of 10 off (which can be adjusted by making the detector area larger -> solid angle).  This is modeled for our irridiator, not for the DHS application.  The LLD (lower level discriminator) is essentially a voltage gate - voltages higher than some threshold LLD will be allowed through to the Multi Channel Analyzer (MCA).  The LLD can be thought of as a channel number threshold. 

 The final plot shows the neutron gamma discrimination.  For DHS we need to be able to discriminate 1 in a million (can't have any false alarms), and we are about 5 in 10,000. 

Not to shabby, not to shabby.
