Charles Newsom:Research

As an experimental particle physicist, C. Newsom participates in many experiments around the world. He is currently involved in completing an analysis of a charm baryon experiment (SELEX) at Fermilab and in the research and development of a Pixel Detector at a new Fermilab colliding beam experiment (BTeV). He also helped lead the design and construction team of a new test beam facility at Fermilab. This facility is now up and running. It is being used by 2 different detector groups within his collaboration (CMS) and several other international groups.

To this end, he has two laboratories at the University of Iowa equipped with the following capabilities;

• Linux computer farm with 6 cpus and a two terabyte disk system.
• High Efficiency Air Filtration system (HEPA) for VLSI silicon chip work
• PC based, computerized data acquisition systems - Camac and Labview based.
• CAD and CAE (mechanical and electrical) software design systems.
• Microprobe test station and Coordinate Measuring Machine (CMM).
• A unique Young's Modulus apparatus for non-destructive testing of solids and liquids.
• Laser Displacement Meter for sub-micron measurements.
• Vibration facility for stressing different materials.
• Vacuum chambers for thermal, mechanical and electrical testing of fuzzy carbon, aluminum, and steel pixel modules.
• Multiple chillers for thermal expansion measurements, thermal stress, and use with the vacuum chamber setup.
• Cable Flexor for testing state of the art multilayer cables under millions of mechanical stress cycles at room temperature and below.
• Two radiation damage (neutron and gamma) facilities.
