The specification and picture of the dE silicon detector is shown in the attached photos.
The detector  has an effective area of 134 x 123 mm and  320 micrometer  thick
There are 26 vertical strips. They are combined into 2 readout channels (top and bottom which respect to the orientation of the detector in BRIKEN)

This is consequence of DACQ crashing because LN2 filling!

new calibration for F11

Using a value of 70 MeV energy loss and the file 161107_0833_Overnight.root
We obtained new peak positions: for V1A7C3 peak at 5398 (F11 right), for V1A7C4 (F11 left) peak at 6060

F11_rigth (V1A7C3): 0.01297
F11_left (V1A7C4): 0.01155

AIDA plastic (veto) and Si de calibration

For the calibration the Compton edge of the spectrum seen in the detectors was used.
There is a large uncertainty in that determination, since the spectra are not so clear in terms of shape.

For the spectra V1A7C13_EFIR (Si de, top) the channel position is 12900 units

For the spectra V1A7C14_EFIR (Si de, bottom) the channel position is 12950 units

For the spectra V1A7C9_EFIR (AIDA plastic) the channel position is 10425 units

These corresponds to the following calibration factors using 0.9 MeV as the Compton energy from Co source:

V1A7C13_EFIR (Si de, top): 6.976744E-5
V1A7C14_EFIR (Si de, bottom): 6.949807E-5
V1A7C9_EFIR (AIDA plastic): 8.633094E-5

62Ni on 6 mm C target between MUSICs

The background before was 0.36 neutrons/s
Now it is around 10 n/s
With 3100 counts/s at F3 we have of the order of 25 neutrons/s
There is an slightly higher than 10 factor between the rate of 
the plastic top and bottom (13 cts/s vs 1ct/s).
Rate at F11 (plastic) 900 cts/s.

We start a proper measurement with DLT

They will measure with 6mm C target (between MUSICS) for 
about 45 minutes and then 15 min without target.
CH2 target at F7 is OUT (beam going directly to F11).

Figure with rates: F11 (black), BRIKEN (red), Clovers (green)
V_PL_T (blue), V_PL_B (pink)

Figure with F11 spectra: Right (red), Left (blue)

Figure with time correlation between F11 and BRIKEN
The number of correlations (integrated spectrum minus flat background)
is 73063 very close the number of detected neutrons 73899
The difference 833 agrees well with the expected number of background
neutrons. That is: for every neutron detected in BRIKEN there was an 
ion passing through F11 (!?).
There is a funny double structure in the first 20 microsec.
94% of the neutrons are detected within 200microsec

Figure with the spectra of Veto plastics Top (red) and
bottom (blue). There are 7.5 times more counts in T than in B.
One can see in the Top peaks at 3MeV and 12MeV 
(corrected from 6 and 25 MeV: wrong calibration!!)
and show signals up to very high energy (GeV)

Figure with the time correlation between Veto Plastics and BRIKEN
Top (red) Bottom (blue). There is a time correlation with Top veto plastic
for 15% of the neutrons in BRIKEN (11440). There  are 18 times less 
correlations with the Bottom plastic. 
WARNING: The correlation was done for signals above "20MeV"
in the V_PL_T spectra i.e. only including the second bump"
