Jan | Analysis | Xrays from 118Te & 124Xe | 2021 |
Attached is a plot of the uncalibrated energy spectra taken with the 90 degree xray detector for 118Te (red) and 124Xe (blue).
Shown is the region covering the K-alpha and K-REC peaks.
Calculating the ratios (Te/Xe) for K_alpha and K-REC energies from theory one gets:
K_alpha (theory): 0.9236
K-REC (theory): 0.9308
Without energy calibration we get the following ratio (using channel numbers):
K_alpha (exp): 0.9293
K-REC (exp): 0.9344
Taking into account that the channel numbers are not calibrated, the agreement is still very good.
In summary we can be sure that we have 118Te stored at 7AMeV. |

Sensitivity of SIS trafo has been changed, thats why the the SIS particle number is smaller, but intensity did not change.
Parallel injection into cave c has started. This brought problems with the timing for the stochastic cooling. |
