DESCRIPTION:Speakers: Markus Zerlauth (CERN)\n\nScope\nHL-LHC IT String Da
 y VI – Event Description\nDuring the HL-LHC IT String Day V in 2025 (eve
 nt link)\, a review was conducted on the lessons learned from the installa
 tion\, component interconnections\, individual system and short-circuit te
 sts. The event also covered a report on the project status\, as well as sa
 fety aspects related to the remaining installation work and the upcoming c
 old powering operation period.\nHL-LHC IT String Day VI will begin with a 
 general introduction revisiting the recommendations from the previous IT S
 tring Day. It will also provide a status update on the project\, results o
 n the RUN1 and a brief summary of the next steps. Additionally\, the sessi
 on will highlight the organization of operations\, detailing key roles and
  responsibilities that were implemented for the Operation phase.\nThe main
  objectives of the event are outlined as follows:\na. Present lessons lear
 ned from recent activities\, including the\n\nRepair performed on the N li
 ne and the feed forward to the HL-LHC. Remaining validation tests that cou
 ld still be valuable? \nCryogenic Commissioning and operation\, thermal C
 ycle after Run1.\nWarm powering systems (crow-bars\, decoupling\, stabilit
 y\, interlock logic).\nCold Powering of the Circuits.\nQuench detection an
 d protection systems (thresholds\, instrumentation\, commissioning strateg
 y\,...).\n\nWe will address the nonconformities detected in the IT String 
 during the cold operation. \nb. Report on the current status of test proc
 edures for the IT String Hardware Commissioning\, including the readiness 
 of associated software tools (supervisory\, analysis…) to be used as wel
 l for the HL-LHC HWC.\nc. Describe remaining planned activities related to
  the String Validation Program during Run2. \nd. Discuss the present stra
 tegy and planning for dismantling. \nAdvisors nominated by the HL-LHC Pro
 ject Leader and the TE Department Head will be invited to provide their fe
 edback and recommendations to the Management and share their comments with
  the HL-LHC WP16 core team.\nChair: Markus Zerlauth\nAdvisors: Rüdiger S
