Bogdan B. Niczyporuk, 81, died on September 5, 2017, due to complications after surgery to replace a pacemaker. Bogdan was preceded in death by his wife of 31 years, Nina.  He is survived by two sons:  Marek A. Niczyporuk and J. Michael Niczyporuk. Bogdan, a member Jefferson Lab’s Physics Division staff, retired in June 2003.

In tribute to Bogdan, retired Hall B Leader, Bernhard Mecking wrote: “Bogdan joined CEBAF in 1988 as one of the first members of the Hall B staff, the team that had been charged with the design and construction of the CEBAF Large Acceptance Spectrometer (CLAS). Bogdan's prior experience had been working in large collaborations at DESY (Germany) and SLAC (Stanford University) on the analysis of high energy electron positron collisions.

Capitalizing on that prior expertise, Bogdan was charged with developing the computer code that determined the properties of charged particles (momentum, direction, particle type) from the coordinates measured by the CLAS particle tracking system. This was a particularly difficult task due to the inhomogeneous magnetic field of the CLAS magnet and the expected high data rates requiring fast and efficient algorithms.

Bogdan took on the challenge and successfully developed the computer programs that still form the basis of the CLAS data analysis. He will not only be remembered for this major effort, but also as a team player and for his contributions to the overall Hall B physics program.”

Family members invite friends and colleagues to a graveside service for Bogdan on Saturday, September 16 at 2 p.m. at the Peninsula Memorial Park. The Peninsula Memorial Park is located at 12750 Warwick Boulevard, Newport News, VA 23606.
