This is the home of the P3MD Labs. The labs were founded by Daniela Bortoletto and Ian Shipsey, past faculty members in the Purdue Physics Department. This wiki is intended to briefly introduce the lab facilities and to publish the lab measurement results for the CMS upgrade R&D.

The P3MD (Purdue Particle Physics Microstructure Development) facility at Purdue University contains two fully equipped clean rooms for the design, testing and assembly of detectors for High Energy Physics. These clean rooms are part of a complex dedicated to microstructure detector development and fabrication including silicon strip and pixel devices and micro-pattern gas detectors. The total clean room space is 3000 sq. ft. in three laboratories containing a CMM, wirebonders, flip-chip bonder, assembly robots, electrical testing equipment, probe stations, optical tables and test stations, microscopes and high precision measuring devices.

The labs are fully equipped with computer facilities for control, data acquisition and analysis. The labs have both temperature and humidity control and HEPA filtering of the airflow to class 10,000. Included in the clean rooms is additional space of class 1000. In a separate location, there is a detector irradiation facility with an X-ray source and an ultra-clean gas delivery system.

Other technical resources are available, such as machine and electronic shops within the physics department, a central machine shop and state of the art facilities on campus, such as SEM, TEM (Transmission Electron Microscopy) and EDS (Energy Dispersive Spectroscopy). In addition to the technical staff, an engineer and technician, there is the normal complement of graduate students and research associates working. There is also an exceptional pool of talented undergraduates who work on R&D and detector construction projects.

P3MD has been a valuable resource in support of past experimental high energy physics projects at Purdue, including CLEO, CDF, CMS, MPGD (Micro-Pattern Gas Detector) development, Whipple and VERITAS, and is utilized in our current LSST and CMS upgrade detectors for SLHC projects. We have experience in design and testing of silicon micro-strip and silicon pixels for CDF and CMS. We use Autodesk 3-D CAD design tools and ANSYS FEA simulation tools for mechanical development, and have extensive mechanical experience acquired in the design, fabrication and assembly of the silicon detector for CLEO III, and the mechanical design, prototyping, and assembly of the CMS Forward Pixel detector.

An introduction to P3MD labs and our experience are available in PowerPoint slides here and in PDF format here.
