Sarah | List of to-dos |
Process alpha data
- Compare pulser width and alpha width to calibration spectra (shaping amp with 1us and gain 50x)
- Does photodiode data process OK or is it a problem with the oscillations?
Process LiF data
- Any pile up issues? Problems with gamma flash?
Online monitoring:
- Check leakage every few days, check lab temp.
- Check alpha peaks of 26Al contaminants - Gd, B.

Check on PHDI pulser width:
205170 (first in beam run) - 1.1% FWHM (at 8275 ch)
205439 (01/09/16) - 1.0% FWHM (at 8008 ch)
Seems to be holding up OK at present. |

Sarah | SPD card changed |
14 bit card replaced for DEED 9-12, to prevent issue with pulser arriving before gamma flash. |

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 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). Planning torun with 1.75 microsecond delay for approx. 1 hour, change to 5 microsecond delay. |

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. |

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. |

Nikolay Sosnin | Change of Pulser Setting |
The pulser has been switched from triggering from beam trigger to running at a 10 Hz rate, and will now appear in random places in signal traces. Planned to run overnight measuring LiF3, switch to empty + detector in beam in the morning. |
