Martino Trassinelli | Runs | Change in the gas-jet density | We reduced the pressure of the gas-jet target
at 0:45AM. Now it is about 7E11 (indicated
as 7x10E11 in the webpage of the control).

Martino Trassinelli | DAQ | mbs acquisition restarted | TDC changed and acquisition restarted.
We have now a 2D histogram time vs energy.
We should have some clues to solve the mystery. |
