# Preparation for second round Interview for grant to do PhD in Paris
|
||||
|
||||
length: 10minutes + 10minutes questions
|
||||
|
||||
## Outline
|
||||
1. Airshowers / Ultra high energy / Radio Signal
|
||||
|
||||
2. Radio Interferometry principle
|
||||
|
||||
3. RI requires good timing -> work in internship
|
||||
mention, but put most in [backup slides]
|
||||
|
||||
4. Direct Advantages of RI
|
||||
(follow airshower through the air)
|
||||
|
||||
5. RI, CRs and Neutrinos
|
||||
(better direction reconstruction is interesting for Ns not for CR)
