The U.S. Million Person Study of Low-Dose-Rate Health Effects
There is a critical knowledge gap regarding the health consequences of exposure to radiation received gradually over time. While there is a plethora of studies on the risks of adverse outcomes from both acute and high-dose exposures, including the landmark study of atomic bomb survivors, these are not characteristic of the chronic exposure to low-dose radiation encountered in occupational and public settings. In addition, smaller cohorts have limited numbers leading to reduced statistical power.

Novette is a large, two beam, two wavelength laser facility at Lawrence Livermore National Laboratory. The Novette laser projected performance exceeds that of the 20 arm Shiva laser and the frequency multiplying capability provides more efficient target interaction. Novette is comprised of two arms of the Nova laser. New designs allow these two arms to exceed the performance of the 20 arms of Shiva. Assembling these two arms on an accelerated schedule allowed the experimental program to continue with minimum interruption. The laser has been operational since January 1983. More efficient laser amplifiers allowed the performance to be achieved with half the capacitor bank used on Shiva. The pulse power for Novette uses high-density capacitors, instrumented dual ignitron switches, 100 KVA power supplies and a control system based on LSI/11 Front End Processors (FEP's) and fiberoptic links. The bank contains 11 MJ of stored energy at 22 KV. Construction of the pulse power system took a year. The laser was completed in about 15 months. This paper is a summary of the pulse power systems for Novette; the flashlamp power system, the pulsers for the various optical shutters and the pulse power control system.
