• Organise WP meetings
Task 8.2 Purification and monitoring (Task Leader: M. Campanelli, UCL)
• Validate the scaling of purification systems for massive cryogenic detectors
• Assessment of common measurement techniques for purity monitoring
• Assessment of techniques for the control of liquid levels and for the measurement of the thermodynamic conditions in cryogenic detectors in the liquid and gas phases.
Task 8.3 Charge readout and double phase (Task Leader: D. Autiero, IPNL)
• Assessment of ionisation charge readout techniques in liquefied noble gases
• Development of double-phase techniques for the ionisation charges amplification
• Assessment of charge readout front-end cryogenic electronics and large scale digitisation systems
• Definition of a basic setup (detector + associated electronics) for sharing in the HEP community
Task 8.4 Light readout (Task Leader: I. Gil-Botella, CIEMAT)
• Evaluation of large area photo-detectors for the readout of the scintillation light in liquefied noble gases
• Assessment of wavelength-shifting techniques for large area conversion surfaces in cryogenic detectors
• Assessment of the digitisation techniques of the scintillation signals in liquefied noble gases and definition of a basic setup (photodetector + associated electronics) for sharing in the HEP community
Task 8.5 Very high voltage (VHV) (Task Leader, A. Rubbia, ETHZ)
• Reviewing of very high voltages O (100kV-MV) generation techniques
• VHV transport, connection to VHV generators and design of VHV feed-throughs
• Characterise phenomena related to high fields in noble gases and liquids and electrical breakdown
• Characterise cathodes and drift field cages for noble liquid’s time projection chambers
Task 8.6 Magnetisation (Task Leader: P. Soler, Glasgow)
• Evaluation of magnetisation based on Superconducting Transmission Lines (STL)
• Evaluation of magnetisation based on High Temperature Superconducting (HTS) lines
• First tests of the novel magnetisation schemes
