RUN0040 8 MeV source run with liquid hydrogen |

RUN 0040. started 7:23 am
8 MeV source was set upstream at 0 degrees to confirm that the target is filled with liquid. The target has been cooled since 4 pm yesterday. From the record of temperatures and pressure, it is likely that hydrogen stays in the liquid phase. It has yet to be confirmed if hydrogen inside the cell is still in liquid or partially evaporated.
target cell 18.180 K
heat shield 114.62 K
H2 gas -0.23 atm
M2C 3.09e-6 mbar
There are events in T5 and T6, but without any clusters formed at an energy of 250 ADC channels (expected energy for alpha particles that traverse hydrogen gas). Need more analysis to conclude. |
