Paul Scherrer (1890 - 1969)• Studied physics and mathematics at

the Swiss Federal Institute of Technology (ETH) Zurich, in Königsberg and Göttingen in Germany

• 1920: Director of The Institute of Physics at the ETH Zurich. Became well-known for the clarity of his lectures

• Researched X-ray scattering on crystals, liquids and gases. Later research work was in nuclear physics

• 1946: President of the Swiss Study Commission on Atomic Energy

• Involved in the founding of CERN

Activities in the Experimental Particle Physics

CMS

• Pixel (hardware only)– Construction of the pixel barrel– Development of ROC, sensor, interconnection technique (bump bonding), HDI, etc.– Construction of 800 modules and their integration

• Electro-magnetic calorimeter– Development and burn-in of APDs

Low and medium energy physics (at PSI)

• MEG look for the forbidden decay e (test of super symmetry)

• Life time (FAST and LAN)

• e branching ratio

Physics with UCNs

• nEDM electro magnetic moment of the neutron

Projects involved

All involvement comes from the PSI-pixel group

P2: Hybrid pixels detectors for upgrade of the LHC experiments

• T. Rohe, PSI staff member, sensor development for CMS pixels

• J. Sibille, ESR hired by the MC-PAD ITN

P9: Pixel readout electronics for upgrade of the LHC experiments

• H.-C. Kaestli, PSI staff member, part of the design team for the CMS pixel chip

• R. Horisberger, PSI staff member, head of the experimental group, CMS pixel project leader

• N.N. ER to be hired

TR14, 13.01.2009

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)

Summary

PSI is a large multi disciplinary research institute

• Staff ~1300, annual budget ~290 MCHF

• Runs several large facilities– Cyclotron– Neutron Source (SINQ)– Synchrotron (SLS)– Reactor (Proteus)

• Large number of technical services and workshops– Interesting for all kind of “hardware related” research
