Engineering Development of the DarkSide 20k AAr Cryogenic System

• Tiziano Baroncelli (CERN)
• Torsten Koettig (CERN)

Room: 30/7-010 Abstract: The development status of the atmospheric argon (AAr) cryogenic system for the DarkSide 20k experiment is presented. The presentation covers the progress of the proximity cryogenics contract, as well as the design, fabrication, testing, and procurement activities performed at CERN for the AAr warm panel and cryostat membrane.

Design development for HL-LHC cryogenic signal conditioning rad-tol electronics

• Torsten Koettig (CERN)
• Nikolaos Chatzipapas (CERN)

Room: 30/7-010 Abstract: High Luminosity LHC introduces several challenges in the realm of electronics. Foremost among these challenges are the design and production of new radiation tolerant cards, radiation-induced, aging and temperature effects on modern electronics, cards protection during electrical quality assurance testing, while maintaining continuous accelerator operation and ensuring reliability. This speech targets to present these challenges in a straightforward manner, aiming clarity and bolstering collaboration among CERN groups.

Design and implementation a of smith predictor with dynamic delay estimation: case study, SM18 string cryogenic cooling loop.

• Nikolaos Chatzipapas (CERN)
• Torsten Koettig (CERN)
• Keanu Buch (CERN)

Room: 30/7-010 In the context of cryogenics control processes within a string of SM18 cooling loop with a cold compressor unit: One of the many challenges is dealing with time-varying delays, non-linearities and constraints within process. This speech aims as show casing a variant of a smith predictor to control a process with a time varying delay for setpoint tracking and disturbance rejection with the main goal being to add robustness to the process.
