Observations:
- We should increase the gain of F11 plastic (now a bit to small)
say by a factor of 2. Calibration is probably wrong!?

Start of parasitic Ca beam
(main experiment "New isotope search", Ahn et al.)

New directory: /data/1703Ahn/

Configuration file: 170329_Conf_BrikenFull.xlsx

New calibration of F11 plastic

We decided to have both a low gain and a high gain 
for F11 plastic dividing the signal from the TFA 
with a "T" and using in one branch a 20db attenuator (reduction by 10)
and sending to two different DACQ channels.
The gain of the TFA was also reduced to x2

V1A7C3: F11_PL_R (Low gain: ~60MeV)
V1A7C4: F11_PL_L
V1A7C5: F11_PL_R_HG (High gain: ~600MeV)
V1A7C5: F11_PL_L_HG

The last version of Briken tools repository has ben installed at d05, this repository includes the Merger and the BrikenOffline codes, as well as a CommonTools folder to share scripts and code.

For update versions, just type in the desired directory "svn update".

To Launch the processes:

Open 4 terminals:

Terminal 1 (DataSink) type:

>ssh aida@d05

>cd /home/aida/DataPackage/DataSink/Linux64

>DataSink -i 3

Terminal 2 (SynCheck) type:

>ssh aida@d05

>cd /home/aida/SyncCheck

>./SynCheck

Terminal 3 (BigRIPS Data Relay) type:

>ssh aida@d05

>cd /home/aida/ribfts/ribftssender

>./ribftssender_mar17ca debug

(specific for current 40Ca parasitic run because we are not sending
a pulse signal to  BigRIPS as trigger but receiving triggers from
BigRIPS to create the pulses)

Terminal 4 (AIDA Data Relay) type:

>npg@aidas1
>DataRelayFilter -n 10.32.0.12 -p 10307 -I 2

"-I 2" selects ID 2 as the one for the AIDA data stream, 
which must correspond to the one expected by the DataSink in the d05 PC.
The programming transmitting the data from AIDA to the DataSink includes an 
intermediate filtering step. This selects only correlation scalers from one 
module (and possibly ADC values from one channel in that module).

Gasific MainWindow (Briken Data Relay):

   In the DAQ Control tab: Click "Start Sync Monitoring" button.

   In the pop up window set server ip and port (ip:10.32.0.12, port:10305)

By default this perform a check on the differences RIBF-BRIKEN and AIDA-BRIKEN.

In case that BRIKEN is not running, the option "SynCheck -M 1" check the differences 
AIDA-RIBF and BRIKEN-RIBF, while "SynCheck -M 2" checks RIBF-AIDA and BRIKEN-AIDA

To synchronize:

   In the Gasific MainWindow, DAQ Control tab: Click "Send Sync Pulse" button

Today, Gabor and I discussed with Nathan from ORNL about the biasing system used for Ge, 3He, Plastic, and others.  Phong is also a bit familiar with the system (edit also 
Shintaro 
Go).  While there 
is supposed to be a manual, Gabor and I did not find it.
In case of trouble: contact Nathan Brewer Gmail: Brewer.nathant@gmail.com Skype: nathan.t.brewer

Log in to high voltage PC:

$ ssh -Y pixie16@10.32.6.161
passwd: ************

For HV readout, run firefox in the background

$ firefox &

You can probably check the history or restore pages, but it should be pointed
at 192.168.13.239

It updates automatically every several seconds.  Unless the HV monitor is
running, it may show nothing...

For temperatures:

$ cd ~/DAQ_1/kelvin
$ ./kelvin-read

(there are options to kill all temperatures)

For applying existing HVs (BE CAREFUL!)

$ cd ~/DAQ_1/hv-mpod
$ ./hvmon

If you want to change the voltages (up or down) kill this with Ctrl+C

To alter bias values or change which ones are on, you can edit the file:

$ ~/DAQ_1/include/hvmon.conf

Once the file is saved, restart hvmon.

We are running the above in a GNU screen session, with firefox on one computer.  It has a note taped to it.  Please don't use this computer for other purposes unless necessary!  
Let me note that the PC we log in through has essentially no .screenrc file so you can barely understand you are actually using screen.  If you are not very familiar with 
screen, better not to touch it.  I will put a better .screenrc later (but I also don't want to change the setup now).

Ge voltage application

LN2 filling was done yesterday before lunch

D is the beam left side Ge
	MPOD	name
	U300	D4K
	U301	D4R
	U302	D4G
	U303	D4B

83.7 K, with 300 V

G is the beam right side Ge
	MPOD 	name
	U304	G7K
	U305	G7R
	U306	G7G
	U307	G7B

79.6 K with 250 V (except G7R at 300 V)

All analog signals are seen in the oscilloscope with reasonable behavior

28 Mar 2017 15:56:03 

Ramp up all Ge clovers.

D at 3000 V for all

G at 2500 V for all (except G7R is 3000)

28 Mar 2017 16:26:39 

Biases are all applied (maybe several minutes earlier)

D4 temp 83.7 K
G7 temp 79.6 K

28 Mar 2017 17:51:09 

Now we ramp up 3He and plastics.  We keep the Ge on during this time.

D4 83.7 K
G7 79.6 K

Everything looks good!

Stopping power calculation (SRIM):
50 MeV/A 40Mg: S=102*1.184=120.8 MeV/mm 
100 MeV/A 40Mg: S=102*0.7129= 72.7 MeV/mm 
(Later: according LISE simulations energy loss of 40Mg  is 88MeV)

What is the energy loss of the "light" particles?

We applied a bias voltage of 100 V to the dE detector

Current read = 0.660 uA

compare with https://elog.ph.ed.ac.uk/BRIKEN/190.  it is slighly lower.
