Louis | OFFLINE | General | Cryo-LH2 | Background |
RUN: 86 to 89
Beam time: 2h30
Beam 40Ca with empty target
Background has been analyzed for 37Capd from run of 40Ca beam on empty target.
Figure shows excitation energy for all Z in 37Ca(p,d), background associated and background substraction
remarks:
As Ionization chamber was not fonctional during 40Ca beam time, it is not possible to apply Z cuts on background. The substraction is so not yet applied in analysis. Solution to reach this goal is under developement |

Jaromir, Giuseppe | EXL-PPT | Software | N/A | EXL calibration, light leak |
Selector.C can be used to adjust energy bad reconstruction in the EXL detectors due to energy leak (see the PDF attached for more information about it) once we already have the coefficients for the energy on EXL crystals. To operate with it, for first calibration coefficient must be deduced. Once it is done the slopes and offset of the calibration have to be inserted in Selector.C file at lines 41 (a[19]) and at line 49 (b[19]). After thqt thresholds must be fixed (line 58, tr[19]) and also gains on the pairs. We deduced gains as the ratio between x-axis and y-axis of each uncalibrated matrix: for each pair (1-2,3-4,5-6,...,17-18) we took the ratio between x=2000;4000;6000 and the respective y value, and y=2000;4000;6000 and the respective x values. taking the averages of those ratios; those were than used as the coefficients R1ex[9] and R2ex[9] in Selector.C (all information on those values and how are used are in EXL.pdf).
Once the variables are set, the program can be executed using the batch file in attachement by typing the line root rootdir/run_number.root -b batch -q from terminal. Here "run_number" is the name of the run to use. It will generate then a .root file (in attachement some output file for run 0430.root). Now the name is "whatever_output.root", and can be changed from "Selector.C"
The program also provides randomization of bins for the operation of sym between contiguous crystals

12C beam + empty target after measurement of 9C momentum distribution.
trigger t1-8 + cats 1 2 %30000 + plastic %10000
start 20h47 / stop 21h08
During this run, wien filter was tuned to center the beam vertically. Final setting is 2.5 kV for negative and 2.5 kV for positive.
The run started with a primary beam intensity of 350 enA. We found that CAVIAR is counting too much and leakage current of CATS1 (0.18 micro A) and 2 (0.14 micro A) are higher than in the 9C measurement. We reduced the beam intensity to 220 enA. The leakage current of CATS1 and 2 are 0.10 and 0.08 micro A, respectively. The plastic rate is about 80 kpps. |
