The target seems identical between the two runs... We will have to investigate to understand what is going on.

The decision is to change the target 5 for the target 4 104um from georges.
The two spectras from run 2003 (target nr6) and 2010 (target nr 5) are identical. The peak at low energy correspond to the first excited state in 15F.


In the picture, target N°4 is written 104 µm
N°5 100 µm GoodFellow
N°6 187µm

In the attached figure it could be seen that with the target No5 (run 2010) lower energy resonances were visible (lower part of the figure), which is not the case with the target No4 (upper part)from run 2013.

GOODFELLOW or mounting error?

Target -> Thick target (Sandwich target ??)

The predictions are different....

At large angles, the 5/2+ peak (at 2.78 MeV) is cut because it goes to lower energies in lab. If the background at 4 MeV is normalized to the one at 0°, there is no very broad-resonance at high energy in large angles.

the beam intensity dropped to 22 pps so we stopped
Pending, e744, Sat May 26 13:22:08 2018, Francois, BEAM, General, , problem with CSS1 
There is a leakage of water in cavity north of cyclotron CSS1. I discussed with Alain Savale.

There are 2 options:

1) We take the beam as it is, probably deteriorated, with a lower intensity. There is a risk of break up in CSS1. The vacuum of the cavity is maintained probably by a small piece of ice only.

2) They can make a new setting of CSS1, using only one acceleration cavity (south). They would stop the north cavity and reduce the water pressure. In this case the beam is also deteriorated.


Decision:
We chose option 1 and we will observe the stability of the vacuum in CSS1 in time. If the stability is bad, vacuum too bad, later in the day they will decide to go to option 2. This means several hours without beam (may be a few hours).
