PDF file attached with the preliminary analysis of the October 2017 AIDA in beam test.

94Se setting:
File: 150503_1500_1554_94Se.root
Rate per tube (n/s): U=0.966, D=0.263, US=0.538
Ratio to 1st 110Zr: U=2.00,  D=1.89,  US=1.84
Notes:
-Compared to the 1st 94Se setting measurement (12:19-13:19)
there is a drop of 25% in the rate without apparent reason

After the long shutdown the beam is back at 00:30 (06/05)
Intensity is slightly lower 26pnA and somewhat unstable (short time)
Measurement in the morning:
File: 150506_0846_0915_94Se.root
Average rate per tube (n/s): U=3.39 D=0.93B=0.40
Notes:
-The rate has increased by 3.5 in the detectors close to EURICA (!?)
-The rate at the detector below the MUSIC is substantial. 
From the different magnitudes it is clear that neutrons are originated
both outside and inside EURICA.

During the first part we were changing the degrader.
Now they remove the C-6mm target.

So we increase the adjustable degrader to 5.4mm 
keeping the 8mm thick plate for implantation.

We stop and start a new DLT file at 22:02

71,72,73Ni  run

We started at approximately 21:00, only online, not writing on tape. 

The lead is still in the way. We removed the degrader (fully) and the effect is a 5 % reduction of the neutron flux 
(determined using the rate of the rateF11/rateBRIKEN  before and after the change).

F7 CH2 F11 Empty

We remove the 8mm Al plate from inside BRIKEN infront of AIDA
Move AIDA to the central position. We put a 5mm Al plate in front

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
Reset Timestamp

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 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"
