DSSSD 0 aida01 1*L spectra, aida04 **L spectra

Double peak structure feature of aida04 ( n+n Ohmic side ) strips. Single ( albeit sometimes broad peak ) observed in aida01 ( p+n junction side ) strips.
Not currently observed by DSSSD 1-3. DSSSD 0 high energy peak rate far higher than DSSSD 1-3.

Data from last week did not display this double peak but DSSSDs and beam have been moved since.

Unclear whether this reflects radiation damage and/or wafer/active area edge effects on the n+n side.
Might also reflect beam characteristics throughout cycle.

Requires calibration and dE cut to investigate.

JM comment -> early time cut analysis indicates this is a beam effect. DSSD#0 has majority of halo on it so double peak is very pronounced. 
We observe double peak all DSSDs just to a much lower level.
