PCD Improves Productivity Through Team Work

By John DiMaggio

Under the direction of department head Paul Bellomo, the Power Conversion Department (PCD) has achieved major productivity improvements in the manufacturing cycle for the High Voltage Power Supplies (HVPS). The HVPS provide power for PEP-II’s klystrons, the microwave generators used to accelerate electron and positron bunches.

There are 11 HVPS in operation at PEP-II, one at SPEAR3, one in the Klystron Test Laboratory, one at Cornell University and PCD is building two more for PEP-II and there are plans for an additional three to be phased in over the next three years.

John DiMaggio, project manager for the HVPS, supervised the implementation of the improvements, which required a team effort from many of the personnel within the department.

As a starting point, a laboratory was set up in Bldg. 15 dedicated as an assembly area for the HVPS. The laboratory was refurbished by Power Systems Operations technicians, supervised by Serge Ratkovsky.

Ratkovsky and his group also refurbished Bldg. 647, dedicated to the storage of large parts and equipment for the HVPS. This was not an easy task because of the many ‘treasures’ stored there by engineers over the years. Some engineers even cried when their ‘treasures’ were sent to salvage. Steve Lowe, supervisor of Engineering Services, is having the roof repaired and a fresh coat of paint will spruce up the area.

Stephen Jenks, a senior technician in PCD, designed and built a new testing system. A comprehensive electrical diagram was developed by DiMaggio and Cliff Rogers, an associate engineer under Ponce Rodriquez in the Electrical Systems Design/Coordination group. Documentation support was provided by Joe Olszewski, supervisor of Electronic Coordination/Design.

DiMaggio and Rogers incorporated several design improvements to the HVPS blueprints. Bellomo designed a schedule system for manufacturing planning and control. Wayne Linebarger, PCD’s Safety Officer, has reviewed all building and facility changes to assure compliance to SLAC and OSHA safety standards.

The improvements achieved in the manufacturing cycle will result in large cost savings to PCD and SLAC. This will occur through efficiency in parts ordering and control, assembly and installation cycle and the general planning and schedule control of present and up-coming HVPS projects. These improvements were only achievable through the team effort of the PCD employees, who deserve a big ‘Thank you.’
