Single Module loading jigs on Fixture Plate Handling Frame with top cover removed Handling Frame secured to and aligned with plate using 4 x shoulder bolts SA-256 -102 -00/00 Config: Single Module Jigs Central disc with alignment dowels Single Module loading jigs Fixture Cradle alignment pads 2

Single Module loading jig (prototype) Loctite EA 9394 Vacuum connection to hold modules securely to underside of pads SA-256 -102 -31/00 Pickup pads for the prototype (19. 0) are flat. Pads for 19. 1 will be re-profiled to accommodate modules Single Module loading jig with top cover raised showing vacuum passages Status: Design is complete Items are being manufactured, one in Lexan, one in aluminum 3

Pickup Plate (prototype) 3 x micrometer height adjustment Jig alignment dowel Jig alignment pads Modules placed on Pickup Table, each aligned along two edges SA-256 -102 -27/00 Vacuum connections to hold modules securely in position after placement 4

Carrying jig from Pickup Plate to Glue Plate Modules are attached to underside of jig by vacuum Alignment is maintained 5

Carry modules to Glue Plate Single Module loading jig Jig removed revealing 3 x modules located with a precision of ~0. 05 mm SA-256 -102 -64/00 Glue Plate – mounted on robot See presentation on Glue Procedure Glue will be applied to a thin sheet of glass or similar before placing the modules 6

Prototype Loading procedure summary • • • Place modules on Pick-up Plate, align to edges Turn on vacuum pump to secure modules Place Loading Jig onto modules – initially use Lexan version for visibility Turn on vacuum in Loading Jig Turn off vacuum in Pickup table Mount Glue Plate on robot, verify coordinate system Apply glue to Glue Plate Lift Loading Jig off Pickup Plate Place Loading Jig on Glue Plate Turn off vacuum in Loading Jig Wait xx seconds then lift off Loading Jig Repeat multiple times to refine process, timing, glue loading, release height etc. 11

Loading procedure summary • • • • Place Handling Frame (HF) on fixture plate – guide cooling tubes through slot in plate Remove top cover (bottom cover stays in place) Insert tie down straps in 4 places to secure dowel pins Secure and align HF with shoulder bolts Place modules on Pick-up Plate, align to edges Turn on vacuum pump to secure modules Place Loading Jig onto modules – initially use Lexan version for visibility Turn on vacuum in Loading Jig Turn off vacuum in Pickup table Mount Fixture Plate on robot, verify coordinate system Apply glue to Ring Lift Loading Jig off Pickup Plate Place Loading Jig on Fixture Plate Turn off vacuum in Loading Jig 12

Summary • Single module Jigs are being manufactured – one in Lexan, one in aluminum. They are due at SLAC this week • Assemble the jigs and test/develop the process • Design of quad module jigs, Fixture Plate and center core is complete. Detail drawings will be produced when designer becomes available. Manufacture will follow. • Design pickup plate for quad module jigs • Refine module loading procedure • Practice prototype loading (Aidan) • Measure loaded modules with CMM (Carina) • Measure thermal performance (Sam) • Update tooling drawings for 19. 1 i. e. pickup pads will require additional machining and possibly rerouted vacuum pipes • Update models for production tooling • Manufacture production tooling 13

Backup slides Side and end views of the single module jig on the glue plate 14

Backup slides Is a single hole sufficient in each of the pads? If module is not in full contact with the pad, machine a pair of slots Request a tapped hole feature in the Handling Frame between the pins to lightly clamp the pins in place during loading 15
