Tom et al. tuned the trigger this evening, before we began the runs.  (Run 82, or Run 83??)

===TRIGGER===

Trigger condition is: E OR HI/ds

We count the CAMAC OR signals as follows: A,B
    A: Which CAMAC module?  Left to right, 1,2,3,4,5
    B: Which module channel? This is the number engraved on the module by the LEMO output.

==E Definition==
All p-n sides of E detector: 
    RAL 109 discrim cable numbers: 4, 5, 7
       => Corresponds to CAMAC OR Numbers 2,2; 2,1; 3,1, respectively.
    
==HI/ds Definition==
All p-n sides of HI detector: 8, 9, 11
    RAL 109 discrim cable numbers 
       => Corresponds to CAMAC OR Numbers 4,3; 4,2; 5,3, respectively.

ds=Downscale; ds factor is 8 = 2^8 = 256

===SCALARS===

0: Ungated
1: Gated
2: dE (n-n) [Cable 3]
3: E (n-n)  [Cable 6]
4: HI (n-n) [Cable 10]
5: Pulser
6: Clock

===DISCUSSION===
The n-n side of the E detector seems to be noisier than the p-n side.  Thus the p-n side is used for the trigger logic, whilst the n-n side is used for the scalar.

However, there seems to be something confusing about using the p-n side for the true trigger but the n-n side for the scalars.  It means we cannot compare the scalars self-
consistently to each other.  That is, the gated or ungated signals do not have a strong correlation with the individual detector scalars.  In principle if we have enough LEMO 
cables and Fan In/Fan Out modules, we should simply propagate the p-n signals to both the trigger (when relevant, i.e. E detector) and the scalars alike.  For now we don't 
touch anything, though.
