The HL-LHC IT String facility includes accelerator systems such as power converters, quench protection, cryogenics, insulation vacuum and alignment. The applications for the system controls and for the operation of the HL-LHC IT String facility compose a three-layer architecture. The front-end layer is composed of Programmable Logic Controllers (PLC) or Front-End Computers (FEC). The systems’...

13. IST, SCT and Powering Test for the HWC of the HL-LHC IT String (WP16/TE-MPE)

The powering tests for the Hardware Commissioning (HWC) of the HL-LHC IT String circuits constitute an important preparation phase for the HWC in the HL-LHC as the last part of the LS3. This talk gives an overview of the String Validation Program concentrating on the phases preparing and after the first cryogenic cool-down of the string of magnets. It shows the work done to prepare the...

17. AccTesting for the HL-LHC IT String (WP7/TE-MPE)

Aleksandra Mnich (CERN)

The Accelerator Testing framework has been used successfully to facilitate the execution and analysis of thousands of tests during the hardware commissioning campaigns of LHC and during its operations to qualify the powering systems. The presentation covers the extensions of AccTesting and its ecosystem needed to support the commissioning of IT String facility. Describes the framework that is...
