A new directory in the IFICdaq computer has been created for the parasitic measurements during the Fallon Beam Time.

The path of the folder is:
/home/dacq/Desktop/Data/2211Fallon/

All the work during this campaign will be stored in folders inside here.

For the period before the parasitic experiments, the test and check of the detector will be stored in 
/home/dacq/Desktop/Data/2211Fallon/2211FallonPreparation

The Config file for the test is:

Gasific-7.0 Short Manual (Preliminary)

Updated run protocol

These are the files used to create and visualize the hit patterns of the BRIKEN detector.

There are three files needed plus one input data file. The three files are "HybridBRIKENPhysicalHistogram.hpp", "HybridBRIKENPhysicalHistogram.cpp", and "HybryidBRIKEN_Tube_Info_1.txt". These files are attached to this eLog entry.

In order to run this type in a terminal

root -l HybidBRIKENPhysicalHistogram.cpp+

The plus is important, it tells ROOT to compile this with the gcc compiler and then run that compiled version of the code. It runs slow, if at all, in the ROOT C++ interpreter CINT.

The code has been tested with ROOT v5.32 and v5.34, not version 6.

At the bottom of the HybidBRIKENPhysicalHistogram.cpp file is the "main program". In it you can set the input data file, which should be a BRIKEN online root output file, and the 3He energy cuts. It is easiest if all the files are in the same folder. If there are any questions please feel free to email B. Charles (Charlie) Rasco.

The boron rubber from India is BR-2871, price US-$ 2700 for 2pc 1m x 2m x 3.3mm.

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.
(see photo)

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.

Note the shape of the active area of the DeltaE Silicon detector, see previous entry.

From Nov. 9th on we use the Takechi ELOG for the run information:

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.

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
of the degrader.

DLT: 161108_2145_717273Ni_001.dlt

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
DLT: 161108_2145_717273Ni_002.dlt
Stop: 22:48


NO ROOT FILE!

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).

Some spectra show spikes or do not look normal. This should be checked.

Look at BRIKEN, Ring4, Ring5, Ring6, Ring7, D4, G7, Clovers, 
Rate1, Rate2, Rate3, etc.

Reset time stamp: 21.00, 8th-nov.

Probably there was a problem with the clock from AIDA related to the LN2 filling.
So to recover, we need to stop acq (only stop acquisition in DACQ control), 
send to hard (send parameters again) and once all the parameters were sent, 
Send Sync pulse.

We will start to use the internal RIKEN ELOG
It is not clear that we can keep the present ELOG also updated

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)

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)
