New stavelet frame concept agreed. • Order for the stages has gone out and been received by Aerotech. • Visit from Mark Cliffe from UKATC who will do engineering drawings for granite, new vac jigs, etc, etc. • Basic idea for granite table sketched out. • Area in R12 clean room agreed. Work will start soon to remove old ‘stuff’. • New design for pinhole illumination tried and incorporated into granite table design • Fume extraction modelled in wood (awaiting smoke to test) • New optics bought. • Pictures via PC and new optics on screen.(Ivan) • DC to DC stavelet has modified aluminium extensions (now the correct width), and two tapped holes added with solder tags for earth connections.Plan to use 2011 +Bn as adhesive to stick into stavelet. See pictures • Trial fit of DC to DC card done.....see pictures
Modified extensions for DC to DC card As delivered Special cable cut off too short to support Dc to Dc card Plan to fill with adhesive Checking Dc to Dc card overhang in Y...not 6mm!
Top view of DC to DC card 28.3 13.5 Checking fit in Y Question... How thick is the ceramic that the Dc to Dc cards will be stuck to, because...it is not all obvious that the bond area on the extra kapton will fall in the correct place given that the module position is fixed Bottom view
Checking the X fit Not glued in yet but in correct theroetical position Edge of gold pad Where edge of dc to dc should be from ashley sketch
