Valerian and Iulian | OFFLINE | General | CH2 | Simulation Azure 1H(14N,p) and measurement |
We can know conclude without any doubt that we were able to measure resonances from 1H(14N,p)14N. The resolution with a rough analysis and the current bad calibration is around 180keV in the com.
Identification of resonances is still difficult but some structure seems consistent with previous works. Also, at higher energy there are only few measurement so the data taken with 14N this night should be interesting.
First spectra is simulated with AZURE2
Second spectra is Energy in center of mass for ThetaLab between 0 to 4 degrees (T5)
Third spectra is Energy in center of mass for ThetaLab between 2 to 3 degrees (T5)
Fourth spectra is Energy in center of mass for ThetaLab between 10 to 12 degrees (T1-T4)
Fifth spectra is Energy in center of mass for ThetaLab between 15 to 20 degrees (T1-T4) |

e744- Valérie | DAQ | General | N/A | DAS configurations for E744-Summary |
List of the saved files of the DAS configuration used on May-24h and May-25th:
[Note that:
All the files are used on run with the name "e744.das".
It means that, for changing from the present das file to another one for the run, you need to open it in the DAS, then to save it with the current experiment name "e774.das".
then you need to be ONLINE to write hardware, in order to apply the electronic settings.
- file for the CALIMERO configuration with the thresholds set at 1 MeV e744.das = e744calimero_1MeVOK.das
- files for the test runs with the 14N:
the file at the beginning of the experiment on 14N was: e744.das = 744_24MayMANIPok.das
Then for the run 1004 and the next ones, the thresholds were changed to around 500keV on all the telescopes.
Runs 1004, 1005, 1006 The config file corresponds to e744.das = e744_25MayMANIPok500keV.das
Thresholds on CsI for the runs with 14N: MATE 18 Seuil Haut 8220 ; Seuil bas 8160
ConfigCsIThreshBefore8220.png
------------------------------------EXPERIMENT 14O 25 MAY evening 17pm ----------------------------------------------
New DAS file corresponds to the change of the CsI thresholds on all telescopes
e744_25MayEXPok500keVCsIThr.das
This is the file that we will use at the beginning of the runs with the 14O beam.
New threshold pedestals on CsI for the runs: ChangeAllCsIThresholds8210.png
MATE 18 Seuil Haut 8210 ; Seuil bas 8160
Later on, the threshold on MM5 will be increased to around 1 MeV (to reduce the background rate due to the beta).
NB: the files are in:
home/e748/ganacq_manip/e744/das-save
------------------------------------------------------
threshold T1 488 keV
threshold T2 480 keV
threshold T3 492 keV
threshold T4 457 keV
threshold T5 480 keV <----------------Maybe to be changed to 1 MeV later on, during the tuning of 14O, depending on the dead time.

shumpei | MUST2 | Software | N/A | CsI energy calibration for MUST2 telescopes |
Calibration parameter for MUST2 CsI crystals are calculated with run1001-1006.
Attached are dE(DSSD)-E(CsI) plot of all the telescopes and parameters.
The parameter files are in
/home/e748/analysis/nptool/Projects/e744/Calibration/Energy/Calibration/CsI_rough
How to make the parameters;
For dE-E plot, the strongest locus should be proton.
Approximation formula for proton dE (Si 300 micrometer)-E (residual) I used is
(CsI_Energy) = -6.81774+41.1823/(Si_Energy-0.0814779).
Absolute value for the total energy may have some offset, but the gain of all the crystals should be roughly matched.
Maybe we need one more common parameter to adjust absolute value.
T2 Crystal #1 and #10 have no data. As I remember, this is the same as E748 exp. last year.
Crystals #9 for all the telescopes have low statistics. I'm afraid the mapping of crystal #9 is not correct.
->nptool/NPLib/Detectors/MUST2/TMust2Physics.cxx m_CsI_MatchingY[8]=48 but should be equal to 16 (corrected and re-compiled 27/05/2018). |

e744 Iulan, Fairouz, Valerie | DAQ | Hardware | CH2 | Problem of FAG validation +change of ADC parameter for TAC signal |
The Time signal MM_PPT is now in the parameter MCP_HF of the ADC.
The problem was on the FAG signal validation (bad output of the discriminator)
the TAC MM_PPT with start FAG and STOP ppt is now coded in the entry of ADC MCP_HF , add=9 (channel 10)
Previously it was add =3 (channel 4).
Problem of DAQ encountered in the evening (20 pm) no DAQ counting, no FAG from GMT: we first reboot on software (Terminal iolan: iolan must2 all; reboot).
but the DAQ was still blocked.
We phoned to the hardware astreinte (Charles H), he told us to reset the hardware.
The problem was solved by resetting the crates (reset button on the crates ganlx1 and ganlx14 in D6).
The DAQ restarted correctly. |
