Attached is the present setup including all walls, auxiliary detectors, degraders etc. and the Takechi setup.
The lead wall will be removed for measurements (of course...).
Not to scale! Some sizes and distances included. Pictures see Jose's entry ID 110.

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).

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 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"

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

Some photos of the elements in the last part of the beam line
during Takechi run.

After the chamber that includes the F11 plastic detector
there are 2 GSI-MUSIC chambers.

In between the MUSIC chambers there is a sample changer 
with 2 Carbon targets of 6mm and 3mm thickness and also
an empty position.

After the 2nd MUSIC there is a plastic detector for testing 
(could be removed at any time)

Afterwards there is the degrader mounted on a separate table.
In the same table there is a 10cm thick lead wall
to protect AIDA during Takechi run.

Mounted on the shielding are from the beam side the top and bottom 
plastic veto detectors.

On the back side the Si detector is mounted.

The hole in the shielding is covered with
a 2cm thick Al plate to protect AIDA during Takechi run. 

Behind AIDA there is a thin plastic detector
to veto the passing through particles.

Some info on ancillary detector signals

Plastic veto detectors (Top and Botomm):
The dynode signal of the PMT is passed through an
ORTEC 474 TFA amplifier before going to the DACQ
TFA: Gain=6 x min(~x2), Tint=200ns,Tdif=100ns, NonInvert
DACQ channels: Top: V1A7C1, Bottom: V1A7C2
Photo of the signals of both detectors attached 
with 60Co source (with gain changed to 20 x max(~x12.5))
200ns wide 70mV high signal

With this info a rough calibration was established:
for the 2V range an ADC unit is 2000mV/16384=0.122mV
the 70mV (~1MeV) correspond to 574 ADC units which
with the change of gain 6*2/20/12.5=0.048
become 27.6 ADC units. We checked with Gasific
that roughly 1 ADC unit corresponds to 2 EFIR units
thus the calibration is 1/2/27.6=0.018 MeV/unit
NOTE: the calibration in online spectra taken
before noon Sunday 6 was wrong by a factor 2
too large!!!!


Si detector (Top and Bottom halves):
Signal from preamplifier in the low gain mode for the measurement:
we see nothing on the scope with 60Co source. In the high gain mode
we saw the other day a negative 6microsec wide 1mV high
signal with a 60Co.

AIDA plastic veto:
The signal from the PMT is going through a CAEN 
shaping amplifier. The signal has a bipolar shape
with a rise time of 500ns a total width of 2microsec
and a height of 100mV (60Co)

F11 ToF plastic (Left and Right):
The signals are processed  in the same way that the
plastic veto detector with TFA using the same settings.
Polarity of the signal unknown.
Currently we see no signal seems its not connected.
We found later that the NIM crate where the 
TFA  were sitting was not on!
We just made a  calibration with beam particles
LISE was used to estimate an energy loss of 65 MeV for the ions.

Sequence of settings:
1) No target at F7 and Empty target at F11 (up to t=1E6ms)
2) No target at F7 and C-6mm target at F11 (up to t=5.1E6ms)
3) CH2 (10mm) target at F7 and C-6mm target at F11 (from t=5.3E6ms up to 6.8E6)
4) CH2 (10mm) target at F7 and Empty target at F11 (from t=6.8ms up to crash 7.1ms)

It is not clear that we can keep the present ELOG also updated

There is a new plastic scintillator
after the MUSIC chambers

The detector has a central hole of 108mm (with) x 38mm (height)
and is 3mm thick and is placed behind the existing plastic 
scintillator which is 5mm thick.

When you want to start HVs, you may have to change the last bit to be 1.

Then go to the following path /home/pixie16//DAQ_1/hv-mpod and execute the command ./hvmon (The process should start),

When you want to down HVs, you may have to change the last bit to be 1.

Sometime you may get error messages colored red on the status monitor when you down the HVs, then you have to change the config file (hvmon.conf) and set the last bit to be 10 to clear the error messages.
