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 ?

• Electrical cables fixation

• Cooling pipes fixation

Teflon plate supports defined

• Glass fiber part glued on Camera frame

• 400mm x 600 mm reflector foreseen

> 3140 mm

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
