To protect HPGe and 3He tubes from high intentsity primary beam, HV of these detector are off and the HPGe will be dismounted.

Scanning of the BRIKEN detector with the 252Cf source 
along the longitudinal axis (Z axis)

Measurements from Z: -42.5cm to 42.5cm with steps of 2.5cm. 

Measurement during beam production
and measurement with F7 CH2 out, 
F11 C-tar in/out, F7 CH2 in C-target out/in

The spectra have a terrible aspect!

This is consequence of DACQ crashing because LN2 filling!

Efficiency calibration

File "cloversEff.ods" and "cloversEff.xls" contains the experimental efficiency from different measurements
during July and October
(G7 broke before Eu-152 measurement). We can assume the efficiency didn't change from July measurements to
October measurements. 

Check of BRIKEN calibration and thresholds

Installation of BRIKEN PE shielding for beam
related neutrons

The missing metallic pieces needed to mount
the forward PE shielding finally arrive and
we mount it with help of the crane.

The shielding (4 PE slabs + 1Cd-PE slab) has attached 
the support for VETO detectors on the beam side
and for and additional ancillary detector
a large Si detector on the BRIKEN side.
See attached photos.

The distance between shielding and BRIKEN is 40 cm.

... and sashimi (see photo)

The detectors (BRIKEN tubes, CLOVER, VETO detectors, AIDA) 
are mounted, tested and ready for November commissioning,
except beam detectors a Plastic TOF and a Si detector which
will be attached to the PE shielding.
DACQs (BRIKEN, AIDA) are running. The synchronization monitoring
program which was working in June, for some reason is not functioning
properly now and is being worked on (desirable but not required).
The data merger and near-line analysis programs are being worked on.

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
