OBSERVATIONS: stop to change degrader from 19mm to 16.8mm

Background with BigRIPS+ZD already working
No pulser

After adjustment of thresholds the rate of BRIKEN noise
was reduced to 4.5kHz
The corresponding configuration file is:
181030_Conf_BrikenFull_LowThrAdj_masterCLK.xlsx
To be decided if we want to reduce further the noise rate

We also changed the calibration of the F11 plastic to have it in the histogram range
F11_PL_R_LG: 2.73 -> 1.0 
F11_PL_L_LG: 2.32 -> 2.0


Further adjustment of few channels: Now noise rate is 2.7kHz

There seems to be a second component of noise or background

Beam related?

Comparison of current spectra with spectra from Takechi's run

(See attachment)

New configuration file:
170330_Conf_BrikenFull.xlsx

Tha gain of F11_PL TFA was changed from x2 to x4

In Conf file histogram ranges were changed for 
F11_PL_L and _R: 30 MeV
F11_PL_L_HG and _R_HG: 200 MeV
Si_T and _B:  200 MeV

the gain for F11_PL_* was changed to 0.0025 (x2)
Thhe gain for Si_* was changed to 0.0007 (x10)

A new gated spectrum was added: F11RgateSiT

Comments: run 018 was dummy (time reset needed)

We moved AIDA+BRIKEN by 107cm upstream.
See attached photos.

BRIKEN was aligned with the laser and
AIDA aligned to BRIKEN.

BRIKEN system powered and DACQ started after movement.
All looks fine.

Background measurement:

We started the preparation of 2017 campaign

We remove partially the floor rails of EURICA 
to proof that it is possible to move BRIKEN + AIDA.

See attached photographs of the present status.
This will allow eventually to move both detectors by about
1 meter to have a better focus at the implantation position.
This movement could be done with a minimum of cable disconnection
using the wheels of both support tables.

Crates powered up.
DACQ started.
New directory: /data/1703Preparation/

Neutron spectrum looks OK (see attached graph)
All the tubes look Ok.
