Progress with Diskcylinder tooling
• Shielding foil added to cylinder• Thermal feedthrough prepared and fitted• Cylinder and stub wings assembled onto tooling (July)• 4 disk alignment tools made by Manchester• Disk grabber-design by Nikhef-manufactured by
Sheffield/Lancaster• Disk fixations from Nikhef and Liverpool-delivered• alignment target holders designed (Nikhef) and
manufactured (Lancaster)• Disk insertion, alignment (X,Y), capture+removal
(August) alignment better than 100m• Wheels+jacks added and tooling+cylinder have been
moved in and out of the cold room (Sept)

Status of tooling-Oct
• 2nd disk alignment, capture and removal has been performed with D7 populated with services– alignment checked with dummy masses– used interface to disk mini-cylinder– grounding: mini-cylinder and frame grounding– FSI spool+ ground foil handling – work with scaffolding around cylinder
• Work to be done– Thermal cycle of tooling+cylinder in the cold room– Removal and insertion of the beam to be
demonstrated– grabber needs to be improved-stronger springs

• FibresLancaster has volunteered to take on reception testingFibres for disk testing (D1) at Liverpool, D9 delivered and tested ok, length issue
• DCS for D9 will be delivered by RB this week• Cooling pipes
Assume no cooling pipes initially and connect direct to disk as for disk testingRetro-fit cooling pipes at Liverpool/CERN when components ready and connect at STFT for testingCooling-replicate disk testing system and connect direct to the disk-or similarParts delivered and assembly underway at Liverpool

Service handling
• Thermal plug delivered and fitted (Sheffield)
• PPF1 trays for LMTs ready (RAL)
• PPF1 tray holders (Sheffield) Delivered, being sent for anodising• Other parts for LMT handling in progress at (Nikhef+Lancaster)
• Temporary PPF1 for fibres Lancaster have volunteered to make this based on prototype being made at Nikhef At Liverpool we need to ensure we can connect in the cold room—looks good, measurement of fibre length indicated that fibres reach close to window in the thermal plug

Cooling connectioncaptive !Helicoflex not O-ring
LMT connection• checked connection with pcb by
measuring thermistor•use clip on light and dental mirror to check connections
• problem with some mis-alignments of guides•passed back to disk makers, they will check alignment with pcbs•can be fixed in-situ but to be avoided

Testing during assembly
• Ensure connections from PPF0 on disk to TPP on thermal plug are well made before moving into cold room—limited access!– LMT connections: check temperature through
LV, checks connection at PPF0– Check fibres and LMTs by sending trigger
burst using SCT DAQ(RODDAQ being used to test disk)Aim to do module by module in parallel with service laying

Schedule-ambitious!
• 10/11 Assemble service handling– awaiting final parts
• Week of 15/11+22/11 leak check and test cooling, move into cold room and test with D7– cooling being assembled – waiting for DCS cables (due this week)
• End November ready to install D9 and mount services
![Page 22: Status of EC-C assembly at Liverpool](https://reader035.vdocument.in/reader035/viewer/2022062804/56814c1e550346895db92143/html5/thumbnails/22.jpg)
Issues
• Cooling and test of disk with services in cold room– cooling being set up for testing
• LMT delivery and making harnesses– delivery of D9 tapes by end this week ? – tape testing at harness preparation at Glasgow
• Problem with infininion connector at PPF0– cannot be fixed in the cylinder
• Experience !

Testing in cold room
• Based on experience with disks• Move into cold room and cable (1d)• Check cabling (1.5d)• Cooling down (1d)• Confirmation tests (5d)• Characterisation (5d)• Warm-up (with I-V) (1d)Total ~15d per disksCan we run cold overnight ?!
