U: (Up: 2 RIKEN tubes at 40cm from AIDA)
D: (Down: 12 RIKEN tubes at 80cm from AIDA)
US: (2 ORNL 2" tubes close to the floor at 1.8m from AIDA)

Natural background:
File: 150426_Bckg_1425_1805.root
Rate per tube (n/s): U=0.0071, D=0.0045, US=0.0222
Notes: 
-This rate seems quite small but we should remember 
that we are underground. 
-The fact that U is larger than D could be explained as 
related that the amount of PE around tubes is larger. 
-For comparison: 
BELEN-20@JYFL=0.6n/s (no beam), 0.9n/s (beam)
BELEN-30@GSI=1.2n/s (beam)
BELEN-48@JYFL=1.5n/s

110Zr setting:
File:150501_16111810_110Zr.root
Rate per tube (n/s): U=0.483, D=0.139, US=0.292
Ratio to background: U=68.3,  D=31.1,  US=13.2

Individual tube distribution:
U1	0.280	D1	0.087	D7	0.084	US1	0.132
U2	0.249	D2	0.092	D8	0.084	US2	0.188

		D5	0.073	D11	0.069		
		D6	0.065	D12	0.054		

Notes:
-There is huge increase of with beam
-The drop of increase with distance is consistent
with either beam induced or decay of implants

110Zr setting:
File: 150501_1733_1900_110Zr.root (actually 02/05)
Rate per tube (n/s): U=0.869, D=0.242, US=0.516
Ratio to 1st 110Zr: U=1.80,  D=1.74,  US=1.77
Notes:
-We don't quite understand the reason for the near factor two
difference since apparently the settings are the same and beam was
rather stable

In order to investigate the point of origin of the neutrons
we add extra PE covering D5,D6,D11,D12 from the top and
D1,D2,D7,D8 from the front

88Ge setting:
File: 150502_21502333_88Ge.root
Rate per tube (n/s): U=1.271, D=0.349, US=0.706
Ratio to 1st 110Zr: U=2.63,  D=2.51,  US=2.42

Individual rates:
U1	1.340	D1	0.424	D7	0.402	US1	0.576
U2	1.202	D2	0.446	D8	0.381	US2	0.835

		D5	0.359	D11	0.250		
		D6	0.275	D12	0.193		

Notes:
-One notices a relative drop of rate for D6, D11 and D12
pointing to a source located in the vicinity of AIDA

94Se setting:
File: 150503_1219_1319_94Se.root
Rate per tube (n/s): U=1.267, D=0.349, US=0.717
Ratio to 1st 110Zr: U=2.62,  D=2.51,  US=2.46
Notes:
-Very similar to 88Ge measurement

The presently used detector has 48x48x5 mm3 YSO array with 1x1mm2 segments. They are separated with ESR.  We use H8500 pspmt and 2 mm quartz diffuser with rough edges. Coupling is done with sylgard.  Anger logic uses a conventional resistive network with 1kohm and we have 4 position signals and dynode.  The position signals (xa,xb,ya,yb) are split in Low gain branch connected directly to 5V range input in Struck and High gain branch, which uses Phillips fast amplifier to boost the gain. The use of the amplifiers enables to operate the detector at low PSPMT gain and should give us a chance to work with the strong light produced by the implant.  The implant signals were simulated using blue diode and a pulse generator. We observed significant drift of the position for very large pulses, but this was for now attributed to be the pulse shape effect due to the use of the diode and reltively slow pulser.

YSO for now should run at -700 V.  The maximum operating voltage is 1200V and should not be exceeded. At 1200 V the ions induced signals may saturate our electronics.

Tuesday evening:

Detector remounted in the pedestal and aligned with WASABI with 1mm+1.5mm spacers. The pedestal is 25.8 mm tall and the box is 60 mm tall.  We checked also the orientation of the spectra and chose AIDA convention (look upstream). With this pedestal the front of the box is centered with the back of the clover leaf.

Wednestay morning:

I opened the detector and rewrapped it with new teflon tape. I noticed a small piece if sylgard peeled off, which may explain why the we had some edge effect yesterday. The detector was remounted on the new pedestal which will allow it to be positioned at the center of the clover.  The signals looked OK on the oscilloscope.

- Start DACQ computer: OK!
- Create directory: /data/1810Preparation/
- Copy last configuration RIBF139 file:  171119_1126_Conf_BrikenFullYSO.xlsx
- Return PB-5 pulser into crate and set parameters
- Star all crates: OK!
- Start DACQ: OK!
- Rename configuration file and edit to eliminate YSO related parameters
  New Config file: 181016_Conf_BrikenFull.xlsx
- Start 3He tube HV: power the ethernet hub, power the pixie PC,
  edit the hvmon.conf file (only tubes active), run hvmon: OK!
- We realized that current and voltage of VME crate 1 was oscillating.
  We pulled out V1A7 (not used) and it became stable: seems that we are at the limit of 
  power supply: OK!
- We put the 252Cf source in and check gain match:
  only (the gain of) three tubes moved slightly since the last run (one year ago)!
  He006, He134, He135 -> new calibration: OK!
- We move SIS3820 clock from internal to external frequency:
  Setup UK Tektronix clock: 25MHz, square signal, 800mVpp, -400mV offset
  Plug in Lupo module (VME1 crate): OK!


ISSUE: the current placement of the table supporting the MUSIC chamber
is too close to the VME1 crate and one of the modules (V1A4) 
cannot be extracted in case of failure. However V1A7 is unused
in this run and can be used as replacement.

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)

We increase the bias voltage of the dE detector from 20 V to 100 V

Leakage current:

Before: ~0.590 uA

After 0.695 uA

At least during the timeframe in between ~ 21:30 (11/08) - 23:30 (11/09) (161108_2323_717273Ni.root) we see that the silicon dE have a very low counting rate. ~1Hz when the first AIDA detector sees ~600 Hz and a cumulative ~2kHz. The energy range in the dE stops at ~10MeV.

Edit: It appears the Si dE were removed. Some signals are still in the spectra.

Pulsers of He006, He140 are tripled
There is a strange background above n-peak in He034

We started the assembly of BRIKEN and AIDA detectors in their final position
on Tuesday October 4:

Gabor Kiss, Phong Vi, Keishi Matsui, Shunji Nishimura, Shigeru Kubono, PA,
Chris Griffin, Tom Davinson, Nathan Brewster, Shintaro Go, Daniel Stracener,
Ariel Tarifeno, Jorge Agramunt, Alvaro Tolosa, Jose L Tain

Tubes were removed from BRIKEN. PE matrix lifted with crane.
Table rotated and placed in the final position (front wheels 
between forward EURICA rails) by hand. Table leveled (height, angle)
with the help of laser. PE matrix placed back.
AIDA rotated and adjusted to BRIKEN by hand.
