چکیده
An automated spark test system based on combining field emission and spark measurements, exploiting a discharging capacitor is investigated. In particular, the remaining charge on the capacitor is analytically solved assuming the field emitted current to follow the Fowler Nordheim expression. The latter allows for field emission measurements from pA to A currents, and spark detection by complete discharge of the capacitor. The measurement theory and experiments on Cu and W are discussed. Paper accepted for publication in Nucl. Instrum. Methods Phys. Res., A (2004)

متن کاملCERN – EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH Active Quadrupole Stabilization for Future Linear Particle Colliders
The future Compact LInear particle Collider (CLIC) under study at CERN will require to stabilize heavy electromagnets, and also to provide them some positioning capabilities. Firstly, this paper presents the concept adopted to address both requirements. Secondly, the control strategy adopted for the stabilization is studied numerically, showing that the quadrupole can be stabilized in both late...

As part of the ESPRIT GP-MIMD project a network of 54 prototype T9000 Transputers has been integrated into the data acquisition system of the CPLEAR experiment at CERN to perform on-line event filtering. Initial experience with T9000s and their interconnection using C104 packet routing chips is presented together with performance measurements and prospects for the future. (Submitted to Nuclear ...
