PROFESSIONAL EXPERIENCE

FERMI NATIONAL ACCELERATOR LABORATORY Batavia, IL June 1978 to Dec 31, 2019 (Ret) Managed by Fermi Research Alliance, LLC for the U.S. Department of Energy Office of Science.

(Started at Fermi as a Contractor through The Salem Group Nov 1977 to June 1978 when hired permanently.) Special Projects - Mechanical Engineer Jan 2006 to Dec 31, 2019 (Ret) PcT Solid State Imaging with Scintillation Fiber Planes. Beam Tracker RAL MICE experiment UK.

Low Energy Low Mass SWIC Chamber for FNAL M-Test beam line. Provided CMS upgrade support.

Built and tested a first-generation proton system prototype to demonstrate the advantages of a proton CT scan in collaboration between the University of California, Santa Cruz and the proton treatment center at Loma Linda University Medical Center, a pioneer in the field of proton therapy. PPD IR Mode Silicon Inspection: Olympus STM6 Measuring Microscope/IR Mode Silicon Detector Inspection. Tech Specialist - Managed LabA MicroDetector Facility Jan 1992 to Dec 2005 Formerly the R&D arm of the PPD/TC/Silicon Detector Center and is now a Technical Center on its own. Built and managed the facility; kept a broad array of workstations working, supervised two technicians, and performed many technical tasks hands-on. Specific duties included: Managed DOE/FNAL/PPD MicroDetector Group’s three Clean Rooms. Designed and fabricated prototypes resulting in successful assemblies of solid-state silicon detectors. Developed assembly and measuring systems with high levels of accuracy by utilizing the full potential of metrology CMM’s and Optics.

Revitalized older assemblies devices with unique modern systems resulting in substantial cost savings. Managed software and mechanical development teams. Managed DOE Intern Physics students in career orientated projects. National Zeiss CMM User Conference, Chairmen 2003 and 2004. Aided in design with lead scientists on Silicon Detectors for; TPL’s Silicon Trigger, P- Center experiment, D0’s Top Quark & CMS’s discovery of the Higgs Boson, the “God Partial”. Performed design & fabrication of Proton Cancer Therapy (PcT) Scintillation Fiber Tracker which combined with PC software, displays real time images for Oncologist’s to plan Proton Beam targeting of patients. Key Accomplishments:

• DO Run2_a Silicon Detector H-Disk, resolved issues with DO' F-Disk grounding issues with ultrasonic solder to Beryllium technique.

• Developed various unique machinery; Bifacial Microscope to align opposed Silicon Detectors into one detector to 1.3 μ RMS. Design optical microscopes for converting touch probe CMM's.

• Developed a special Nikon Tool Makers microscope to fit into a Zeiss 500 CMM, I found on DOE/Surplus

@ Rocky Flats facility in Denver CO. This modification allowed our group to enjoy assembly resolution unattainable on commercially available equipment.

• Top Quark Discovery, DO Collider Experiment. Development of B-Tev Pixel Detectors

• CMS Pixel Detector development; developed new method of ASIC Kapton HDI Circuitry applied to blank Silicon Wafers and cut to various sizes that matched the CTE of the Detectors.

• Built the MicroDetector's Group's Wet Lab that proceeded all Silicon with Diamond Dicing Saw, DI water rinsing system.

Mechanical Engineer June 2013 to Dec 31, 2019 (Ret) Assisted in the design and operation of mechanical and process systems associated with high energy physic experiments and particle astrophysics detectors.

Performed basic engineering calculations in heat transfer, fluid flow, and mechanical stress analysis. Performed basic engineering tasks from the design stage through review, procurement, manufacture, installation, test, and operation.

Work included design, analysis, fabrication, installation, commissioning, and documentation of mechanical equipment and systems.
