BigBite Calibration

What have I been doing this week?

A.) Still working on BigBite Optics NIM paper:

Made some new plots.

1.) 2.)

B.) Problems with FARM analysis

Farm computer farml5 was decommisioned. Had to recompile my analysis software for a new system. Analysis seems to be working again.

C.) TgY Matrix Element relevance:

3.) 4.) 5.) 6.)

D.) TgPh angle correction:

7.)

Non-dispersive angle coorection according to Penner:

\delta \phi = -(y/R)tan(\beta)

I have estimated this correction and it is not negligible. Therefore I will correct my BB drawing. However, BigBite central bending angle is 25deg (according to NIKHEF), while exit-face angle is 20deg. Therefore I believe this correction does not cancel out in the end. Small correction remains. To be sure, I will check Penner paper one more time.

E: TO-DO -> Get simulation results from John LeRose and Vladimir.
