Project/slides presented: optical lines from UA43 to RA43 (and UA47 to RA47).

Optical line simulations are ongoing. 

• Option1: complex line around the mono rail to use the existing carrotage
• Option2: Go straight (from above the mon rail was actually discussed)
• Option3: trench all along the way up to the new hutch

Christophe needs to perfom scans to make sure there is no 'pipes' in the depth of interest (~200mm). 

--> try to launch them for next TS

--> William to give the DCUM for both sides: UA43/RA43 & UA47/RA47 (from ECR: final position will be confirmed).
