1 CTA Reunion de groupe LAPP,

2 23/09/2014 Catania MeetingG. Lamanna 2 Prototypes waiting for test CSS / dish interface part Prototypes built by Lorima since May Consecutive tube junction Waiting for test slot Each month lost is less time for improvements in case on non positive test conclusion ?

3 23/09/2014 Catania MeetingG. Lamanna 3 Les surprises du prototype manchon Pincement du manchon lors de son ouverture Largeur de rainure longitudinale insuffisante Au serrage contact sur lèvres du manchon Pincement du manchon lors de son ouverture Un petit usinage maison grâce à Laurent et hop dans la caisse !

4 CSS / dish interface part

5 Consecutive tube junction

6 23/09/2014 Catania MeetingG. Lamanna 6 Final definition of details  Cables and pipes supports defined Glass fiber part glued on CSS Electrical cables fixation Cooling pipes fixation  Teflon plate supports defined Glass fiber part glued on Camera frame 400mm x 600 mm reflector foreseen

7 > 3140 mm 3140 mm 800 mm Camera frame : Key values Camera frame deformation parking position) Shiming parking position) Rails mounting parking position)

8 1 - Turn to focus 2- Turn to clamp in desired position Carlos’ slide (Padova) Carlos Diaz’s rail system La définition de la fixation de la camera dans le frame a convergé

9 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

10 23/09/2014 Catania MeetingG. Lamanna 10 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 dish Indeed : crane cannot move once CSS is lifted ! crane Civil work to be foreseen for trestel fixation LAPP is going to start studying transportation and mounting tooling end of this year

11 23/09/2014 Catania MeetingG. Lamanna 11 Access tower definition Mounting area close enough to mounted dish Indeed : crane cannot move once CSS is lifted ! LAPP is going to start studying transportation and mounting tooling end of this year

12 23/09/2014 Catania MeetingG. Lamanna 12 Access tower definition

13 23/09/2014 Catania MeetingG. Lamanna 13 Access tower definition
