11:10 Leakage current for DSSD1 (I2 on leakage current plot) remained 'turbulent'. We dropped the voltage from 150V to 100V. Leakage current dropped from ~4.5uA to ~4.2 uA. We will see if it remains more stable.
Rates in DSSD1 increased during change in voltage so all histograms were zero'd and monitoring code reset. Transient also observed for I3 in the leake current plot (attachment 19)

TD | Sunday 18 February - DSSSD 0 aida01 and aida04 *.*.L spectra |
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. |

Summary
All FEE64s appear to be working (except aida05 which has c. 8 missing channels) with pulser - which
validates the FEE64, ASICs and adaptor PCB.
Electronic noise c. 50keV FWHM for aida01 & aida03 - other FEE64s better/worse.
Preamplifier noise appears to be similar for all FEE64s which may suggest an issue with the test signal chain
