[dsg-hallb_rich] d0 results for mirrors 5 and 5C

[Tyler Lemon]

Hi Marco Mirazita and Marco Contalbrigo,

Over the past two days, Mindy, Aaron, and I took d0 measurements on RICH spherical mirrors 5 and 5C.

After our meeting this morning, I was able to get the program that fits the d0 vs Z curve. Attached are the results as PDFs.

The table below has the fit value and also the radius of curvature from determined by the program.

Mirror
Position
Fit d0 [mm]
Fit Z [mm]
5
horizontal
1.98
2710.21
5
vertical
2.29
2703.53
5C
horizontal
2.26
2708.40
5C
vertical
3.31
2700.78


As we discussed in the meeting today, we'll take additional sets of d0 measurements after trying to limit the background light noise in the room and taking multiple background measurements.

-Tyler
