 Fri Oct 7 17:17:08 2022, Nikolay Sosnin, Change of Pulser Delay
|
Still using pulser triggered from protons. 12 microsecond delay from protons to gamma-flash + 11 microsecond delay from gamma flash to pulser. 20 mV
pulser output into 50 ohm impedance (10 mV final output) of both polarities (using two pulsers, one NE pulser and one BNC PB5 pulser). Changed pulser setting
to run with 11 microsecond delay for approx. 2 hour, then change to an overnight run with pulser running NOT triggered from beam. |

Thu Oct 6 14:58:29 2022, Nikolay Sosnin, Change of Pulser Delay
|
Still using pulser triggered from protons. 12 microsecond delay from protons to gamma-flash + 1.75 microsecond delay from gamma flash to pulser. 20 mV
pulser output into 50 ohm impedance (10 mV final output) of both polarities (using two pulsers, one NE pulser and one BNC PB5 pulser). Changed pulser setting
to run with 5 microsecond delay for approx. 1 hour, then change to 10 microsecond delay. |

Thu Oct 6 11:07:47 2022, Nikolay Sosnin, Change of sample/Addition of pulser
|
Changed from LiF 4 to LiF 3 after running with LiF 4 overnight (run title on n_TOF DAQ was not updated to refelect the change, and still says LiF 4,
but the material setting of the run states correctly that hte run is with LiF 3).
Added pulser triggered from protons. 12 microsecond delay from protons to gamma-flash + 1.75 microsecond delay from gamma flash to pulser. 20 |
