Availability modeling of the proposed International Linear Collider (ILC) predicts unacceptably low uptime with current electronics systems designs. High Availability (HA) analysis is being used as a guideline for all major machine systems including sources, utilities, cryogenics, magnets, power supplies, instrumentation and controls. R&D teams are seeking to achieve total machine high availabi...

56 LLE Review, Volume 82 The primary obstacle to the successful implosion of an inertial confinement fusion target is hydrodynamic instability, which can cause the target to disintegrate and prevent it from reaching the high densities and temperatures required for ignition. The imploding target is primarily subject to the Rayleigh–Taylor (RT) instability, seeded by surface nonuniformity and by ...

The first application of the CERN Unified Industrial Control system (UNICOS) has been developed for the 1.8 K refrigerator at point 1.8 in mid-2001. This paper presents the engineering methods used for application development, in order to reach the objectives of maintainability and reusability, in the context of a development done by an external consortium of engineering firms. It will also rev...

Cryogenic cavitation affects the operation of liquid propulsion systems during first phase a launch. Its effects within orifices or turbopumps can range from mild instabilities to catastrophic damages structures, jeopardizing launch itself. Therefore, ensure proper designing systems, phenomena cannot be neglected. Although hydrodynamic has been studied for decades, impact nature fluid sparsely ...
