QPS2 - Main Points• Upgrade of existing Quench Protection System.• Protection of newly installed sc. Elements (IT, sc. Links, 11T,
IPDs, … )• Ensure compatibility to increased radiation levels in tunnel.• Ensure high level of system dependability.• Possibly re-locate major part of protection electronics to
low radiation areas or surface.• New communication links for data acquisition and
supervision.• Advanced remote diagnostics and maintenance.

QPS2 - Plans• Protection parameters of new devices to be
specified by equipment responsibles (WP3, WP6, WP18) in collaboration with MP3.• Draft specifications for QPS2 ( ~ end 2014).• Study, which parts of the QPS could be
removed from the tunnel (~ end 2014).• R&D from 2015.

EE - Main Points• Upgrade of existing Energy Extraction Systems.• Protection of newly installed sc. Elements (IT, sc. Links, 11T, IPDs, … )• Development of new generation of Extraction Switches:• Semiconductor switch
• Noise-free operation (no arcs)• Very short release times (~200us)• Highly reliable operation.• Low maintenance requirements.• High on-state losses (water cooling required)
• Hybrid switch (electro-mechanic switch parallel to semiconductor switch)• Noise-free operation (no arcs)• Release times ~20ms.• Highly reliable operation.• Low maintenance requirements.• Low on-state losses.
• New design of extraction resistors:• Very fast recovery time (cooling).• Compact design.• Easily changeable resistance
