we lost the beam at 03:20, source unstable
5:55 beam back
sequence of several problems, access issue, HF that went down...
now we run with 5.3e5 pps in Cats |

Fixed, e793s, Sun Mar 14 10:01:36 2021, Juan Lois & faïrouz & Adrien, BEAM, Hardware, CD2, Beam intensity escalated up to 1.6e6 pps
|
At 9:57 the intensity increased up to 1.6e6 pps and we had to call the pcp to put it again to the normal values.
It was solved by 10:07 .
Same incidence happend at 10:17 and then again at 10h30.
The beam operators close little bit the slits to decrease the beam intensity.
The intensity is now 3.e5 pps |

Fixed, e793s, Sun Mar 14 15:20:47 2021, Adrien, OFFLINE, General, CD2, Updated Angular distribution macro
|
The angular distribution macro has been updated and now produce TWOFNR calculation on the fly.
Feel free to add new plots and play around with the parameter.
MakePlot will produce the distribution using Ex and sigmaEx of the state and Eg and sigmaG of the gamma. Efficiency is automatically taken into account using the efficiency provided by manu.
FIT will perform the TWOFNR calculation using The energy of the state, l and j of the transferred nucleon and J of the formed states. Once the calculation done, it does the fit to the data and extract the C2S.
I found the number strangely small so I suspect we do something wrong.
To run it:
Open a terminal
$> lpcgrit
$> npp MUGAST
$> cd e793s
$> root AngDist.C |

Beam went up to 2x10^6 pps in CATS.
Then it went down to 0 for a couple of minutes at 17:13.
Now it is ok, screenshot attached. |

Pending, e793s, Mon Mar 15 00:21:18 2021, 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. |
