Applying the SCR Requirements

Fast Scr Thyratron Driver

As part of an improvement project on the linear accelerator at SLAC, it was necessary to replace the original thyratron trigger generator, which consisted of two chassis, two vacuum tubes, and a small thyratron. All solid-state, fast rise, and high voltage thyratron drivers, therefore, have been developed and built for the 244 klystron modulators. The rack mounted, single chassis driver employs...

Applying the SCR Requirements Method

To date, the SCR (Software Cost Reduction) requirements method has been used in industrial environments to specify the requirements of many practical systems, including control systems for nuclear power plants and avionics systems. This paper describes the use of the SCR method to specify the requirements of the Light Control System (LCS), the subject of a case study at the Dagstuhl Seminar on ...

Using the Scr* Toolset to Specify Software Requirements 2. the Scr Requirements Model

Formulated in the late 1970s to specify the requirements of the Operational Flight Program (OFP) of the A-7 aircraft [8], the SCR (Software Cost Reduction) requirements method is a method based on tables for specifying the requirements of software systems. During the 1980s and the early 1990s, many companies, including Bell Laboratories, Grumman, Ontario Hydro, and Lockheed, applied the SCR req...
