Infrastructure
Proton-cyclotron
• Very high current (1.8 mA) to drive the neutron source (SINQ)
• 2 graphite targets for 6 secondary beam lines (pions, muons)– Particle physics– Muon spin resonance SR
(investigation of magnetic properties of materials)
Resources of the pixel group (interesting for the MC-PAD network)
• Testing equipment (probe station, test boards for readout of chips, etc.)
• Interconnection (wire bonding, bump bonding) and mounting
• Layout tools (Cadence)
• Simulation tools (Synopsys) to be pursued (via Europractice)
