Slide2Remark
The following lines shall NOT be intended as considerations against a possible TCLD (and therefore 11T) relocation in point 7. They are a list of activities to be carried out.
It is imperative that the TCLD and 11 T system are installed in the most effective point in order to have the best return over this large investment

Preparatory work and data needed to evaluate change Update
machine models for cells 9L7 and 9R7 to LS2 levels
Perform scans of the
for cells 9L7 and 9R7 (TS3 and if not possible LS2. Point 7 limited access. Already ordered for tomorrow. To see if possible. Cost paid by WP15)Check services in cell 9 (cable trays, supports, derivation boxes… etc) and add to the 3D modelNeed of new dose (to electronics) level graphics in the DS after LS2 (profile may significantly change with new position, R. Alia private communications) Identification of racks installed underneath the cryostats in the zone and their related radiation hardnessConfirmation from WP11 and WP9 that the He release valves are unchanged (or new scheme) in number and positions Analysis to be performed againRelocation of racks because of the above mentioned radiationIdentification of cabling work in the areaBLM location/number/relocationsPossible needed re-routing of the nQPS cablesRe-simulate TCLD installation in the new position. Change of position lead to change of possible interference to be managed or dismantled from the tunnel in order to allow installation If He release valves change of positon and number → impact on access area and maintenance area of the TCLD, impact on the 11T cryostat and impact on the survey line of sight

Slide8Process recall
The integration of the 11T and TCLD was approved in the integration meeting number 90 of the 3/11/2017
It was approved by the ICL on the 6/12/2017
In order to be
effective, WP15 had asked to the TCC to officially confirm the position of the 11T (request September 2017). This was confirmed on the
7/12/2017. TCC
endorsed this location
given the information available at that time and it stated that the location should be revisited if new information on the quench margin would become availableThe IRIA [Integration Report Installation Approval] was released in version 1.0 20/03/2018The version 1.1 with the differential lay-out was released 10/09/2018. It was the final version for installation In someway we should re-think how ECR process and technical advancement could re-brought on line in order to minimize work repetitionTo edit speaker name go to Insert > Header & Footer and apply to all slides except title page8
