Prototypes waiting for test slot @MPI
CSS / dish interface part
Prototypes built by LorimaArrived @MPI since May
Consecutive tube junction
Waiting for test slot
Each month lost is less time forimprovements in case on non positive test
conclusion ?

3140 mm800 mm
Camera frame : Key values
Camera frame deformation(@ parking position)
Shiming(@ parking position)
Rails mounting(@ parking position)
1 - Turn to focus
2- Turn to clamp in desired position

La définition de la fixation de la camera dans le frame a convergé
Carbon fibers structure are very sensitive to shocks :•CF tubes are monolithic and thick : limited worry•CF ropes are 10mm Φ and of prime importance : be careful !•Camera frame CF skins are extremely thin : be very careful !!
Extreme care & protections are needed during maintenance !
Worries about shocks on CF parts
Possibilité de réaliser des test expérimentaux à l’étude actuellement

Mounting : Civil work & tooling Installation procedure on site will require :
CSS elements assembly on ground
Lifting of complete CSS
Installation on dish
Mounting area close enough to mounted dishIndeed : crane cannot move once CSS is lifted !
crane crane
Civil work to be foreseen for trestel fixation
LAPP is going to start studying transportation and mounting tooling end of this year
