Characterization of 780 nm Optical filter
The 780 nm optical filter removed from the ISB laser room was chracterized in the UITF laser room using Superk Fianum with LLTF contrast filter which provides tunable wavelength. The goal of the characterization was to determine the pass wavelength of the optical filter. The characterization was done in the both orientation of the filter with laser being incident on both the faces as shown in Figure 1 and Figure 2 (Hence two curves of power vs wavelength). Further, the power was also measured without the optical filter being in the path.

COMMENT ON Install Honeywell EBI Virtual Servers (EBIhbm600 and EBIrps600) Microsoft Patches
1L04-3 RF recovered after tuner checks and RFCM replacement.
Cavity resonance found last week after tuner checks and tuner cart found. Tuner position at almost -8 M steps and doesn't make sense unless it was disconnect and ran off original position by SRF or CAMAC card failure. Back operating normal though at 10.5 Mv/m . KMAI readback is a little flaky but not close to warning.

COMMENT ON Install Honeywell EBI Virtual Servers (EBIhbm600 and EBIrps600) Microsoft Patches
I have not spoken to the Honeywell server specialist this morning so I am not certain the work can be done today. I will let you know when he responds. The required time estimate is my estimate which could be less depending upon the number of patches to be installed.
