| The rate in the diamond was decreasing even if the rate in VAMOS was more or less constant. Now it seems stabilized. |

Sarah, Louis, Charlie | BEAM | General | CD2 | Source is running out |
The beam intensity spiked to 9x10^9, so Louis called PCP to ask them to reduce it. He was told that the source was almost depleted, and was presented with two options:
A) Keep pushing the source and run at 5x10^5, but run out completely soon (probably during the night shift)
B) Let the rates slowly drop and open the slits as much as possible, to make the source last longer (perhaps another day). This option is strongly preferred by the PCP team, and is the current plan we are following.
Changing the source would apparently take ~12 hrs. There will be a large meeting of all of the technical staff - including the beam and source experts - tomorrow morning at 09:00, so there may be more information about the best course of action after that.
Wilton was consulted as one of the spokespeople of the experiment, and he approves of this action. |

Sarah, Louis, Charlie | RUN | General | CD2 | Beam returned at 02:45 and stabilised by PCP |
| The PCP team were not able to learn anything new about the state of the source from their diagnostic tests, but they told us that they have stabilized the beam so there should be less fluctuations. They have also opened the slits to their maximum, which now gives us 5e5 pps. |
