KW44 - Leak in Solid Attenuator, posted by Janni Eidam on 07 Nov 2023, 15:57 
|
There was a leak in the Solid Attenuator that increased on Saturday morning when SPB moved the arm number 4 (see last entry ID 236).
We were lucky that a balance developed between the leak and the pumping of the ion pumps, so by setting the setpoints of the three most affected
ionpumps to 5x10-5 mbar we could survive the weekend and save the beamtime. |

- Tunnel + experimental hutch alignment (Mirrors, CRL1 and CRL2)
- Aligned main devices: Optics Peter, x-ray eye, EPIX and Zyla and pin holes.
- Tried some alignment of the NFL (1D) lenses with pin hole and not pre focussed beam. We found a lot of scattering from pinholes which dominates |

After realignement of M1 and M2 we could solve the problem of the elogated beamprofile. Different lens setting were prealignd for the use in combination
with the NFL.
We took data for several 1D diamond lenses together with a Vycor sample to extract the beamsize from the specles. |

We tested pulse on demand scans with scantool and confirmed that there is only one shot per scan point. This was used to print the footprint in
a LIf crystal.
We took caustic scans for 1D diamond lenses using a wire and using specles to extract the beamsize. |
