Motivation
I have realized that I made a mistake measuring the distance of the North cavity waist from the PMC (waist).
I have done the same analysis presented in ID 1660 and adjusted the plan.

Conclusion
A new set of lenses has been found respecting all the constraints given in ID 1660
 

Setup
The waist of the North cavity is located at 1.701m far from the PMC waist. The size is 210um.
The chosen lenses focal lens f"i" (m) located at l"i"(m) are:

l1 = 0.136;

l2 = 0.489;

l3 = 1.041;

f1 = 0.114;

f2 = 0.114;

f3 = 0.229;



 

1. Beam profile

2. Sensitivity to lenses displacement
