As an undergraduate I studied physics at the University of Athens. I entered the university in 1955 after successfully passing a national exam (came up fourth in a field of about 700 candidates). Upon graduation and finishing my mandatory two-year military service, the plan was to teach physics either in a public high school or as a tutor for a private for-profit institution, preparing high school students for the national exam.

By making the hohlraum wall more opaque to the driver energy, the efficiency of X-ray conversion is improved with the addition of depleted uranium (DU) to a gold-only hohlraum [see T. J. Orzechowski et al., Phys. Rev. Lett., Vol. 77, p. 3545 (1996)]. The National Ignition Facility (NIF) point design for ignition requires a DU hohlraum, which is manufactured by General Atomics. The process of creating a hohlraum with multiple layers presents manufacturing challenges. To produce these components many steps are required. The processes for manufacturing an Au-lined DU hohlraum requires single-point diamond turning, sputter deposition, electroplating, chemical etch, and cleaning. These steps combined make a process that yields a fully intact Au-DU layered NIF ignition hohlraum.
