[Dsg-reflectivity] UV reflectivity items to buy

Dear Beni and all,
I apologize for sending this message late.
It is fantastic to know the procurement of the items is moving forward.
I just wanted to elaborate a little more regarding various mirror
reflectivity Q&A stations at Stony Brook, BNL, JLab, and Duke.
I can easily see people ask questions about why we need to fund all of
this efforts. Also, whether we are duplicating the Q&A effort.
In my opinion, there is an overall strategy that requires all of the
mentioned Q&A stations.
1. Q&A station at Stony Brook (single wavelength @300nm): during the
production phase, once a large mirror is coated with the witness
samples, how do we know the mirror meets the requirement? A single
wavelength measurement at Stony Brook at 300nm is required to determine
if a mirror is ready to be sent to JLab for full characterization or
needs to be re-coated due to a variety of reasons. This is also a good
way to monitor mirror-to-mirror performance variation to reflect the
stability of our coating methodology.
2. The BNL Q&A Station is specifically used to measure the witness
samples down to low wavelength, it has the unique feature of measuring
absolute reflectivity down to 160 nm. This is especially important for
DRICH mirrors. Additionally, this will provide important validation for
the JLab measurement in item #3.
3. JLab station by Tyler: is needed to characterize the coated full
mirrors down to 200nm. Measuring the reflectivity across the mirror is
very important. As we already know the mirror center will be coated
thicker than the edge, so identifying localize efficiency will be
extremely beneficial. Couple this measurement with item #2 will give us
a good sense of low wavelength performance as well (via extrapolation).
4. After JLab completes setting up the Q&A station, Duke will probably
take over the responsibility of characterizing every single produced
mirror. I could easily see it is beneficial to replicate the setup at
Duke to utilize the available manpower. There will be great number of
mirrors and huge surface area to characterize. Multiple stations will be
beneficial for the quick completion. (I assume SoLID will also use these
Q&A stations, in this case, it will be difficult to handle the large
number of mirror with just one full size mirror Q&A station)
Regarding the stabilized UV lamp for the pfRICH, it was purchased for
item #1 (Stony Brook single wavelength Q&A station). However, we don't
need to set this up before the full production phase, therefore, we are
more than happy to loan it to Tyler to complete item #3 in the near
future, and have it return when it is needed.
Hopefully, this is also aligns with the common understanding of others.
Please let me know if I missed anything or if you have any questions.
Many thanks
Bill
