Mounted filters, replacement in N2 box
- Filter History and mounted filters of FLASH1 and FLASH2: what filter was mounted at which motor position
- Replacement filters in N2 flow box
Filter transmission
- Transmission of filters calculated from CXRO; the Origin graphs now as pdf for and filter wheels
- : Transmission of filters as measured by PTB as pdf
- : Transmission of Nb, Zr, Al, Si Luxel filters measured between 2.5nm and 25nm by the PTB in comparison with CXRO data
- : Laurents transmissiont measurements for "Rohringer" Beamtime - shows deviations for Si !
