With the resumption of nuclear testing, the Whitney Reaction Test History Test Group utilized telemetry to make data available immediately after a nuclear shot, replacing the recovery, devel- opment, and reading of film. The Test Division continued however to make broad use of oscilloscopes and recording cameras. Test Operations Group- Livermore The Test Division was supported by Test Operations Group. The Group was comprised of the Field Services Unit, L-4 shipping and warehousing unit, and L-6 engineering and construction group. In 1958, Field Services consisted of five staff members augmented by four military personnel. They, as a group, were responsible for collecting and consolidating all the requirements for operational support and administration, including housing, transportation, communication, badges, office space, and equipment, with LRL administration. Field Services took part in nuclear tests and Plowshare projects, II (NTS). including Hardtack I (PPG) and Hardtack With further testing discontinued by moratorium, Field Services engaged in nonnuclear Plowshare testing. Staff to handle these responsibilities were assigned to the islands of Fred and Parry on Eniwetok and Nan and Peter-Oboe on Bikini. More personnel were required for zero-site barges and ship assignments during periods of evaculation. For Hardtack I in PPG, ten men arrived from Livermore and Berkeley to expand the permament staff at the site. At the Hardtack II at NTS. same time, Field Services staff prepared Operations were similar to those at PPG for except that support administration was the responsibility of the LRL-Nevada organization. LRL- Nevada also prepared and published the test schedule, issued two days prior to each LRL shot. The L-4 Section obtained, packaged and shipped all user- furnished equipment to support the Laboratory in the field, stored and distributed this material and returned it to Livermore. Five staff members completed this assignment in 1958. L-6 Section, with seven staff members in 1958, developed all the engineerings and construction requirements pertaining to Laboratory tests, consolidated and transmitted these requirements to contracting firms, and coordinated all construction work in the field. A two-person headquarters office was responsible for directing the work of the three sections. L-6 engaged in two major nuclear tests and two minor Plowshare field projects in 1959. Six engineers were stationed at PPG, assisting in the final phases of construction and support for Hardtack I. L-6 formulated and transmitted to the contracting and engineering firms all the engineering and construction requirements for the Laboratory’s program, and coordinated field construction work. After Hardtack I was completed in July 1959, one person from L-6 remained through August to complete transportation and removal of equipment. One engineer was detached from operational support take up residence at the Chariot Camp in northwestern Alaska. L~6 prepared most of the Plowshare projects, including balloon shot and Project 58-A safety test at NTS. Plumbbob to
