The Advanced Test Accelerator ( ATA) is a pulsed linear induction accelerator with the following design parameters: 50 MeV, 10 kA, 70 ns, and 1 kHz in a ten-pulse burst. We will describe and discuss the difficulties, problems, and solutions encountered in making optical measurements in the ATA environmentĪdvanced Test Accelerator ( ATA) pulse power technology development Gated TV cameras are located outside the accelerator tunnel, because the tunnel is inaccessible during operations. A large number of optical lines of sight (LOS) are routinely deployed along the experimental beamlines that use the ATA beam. Optical diagnostics play an important part in measuring experimental parameters such as the beam current density profile. Examples of such components are integrated circuit elements, hydrocarbons such as Teflon insulation, and optical components that darken, resulting in transmission loss. High radiation (x-ray, gamma, and neutron) and electromagnetic interference levels preclude placing components near the beamline that are susceptible to radiation damage. Diagnostic targets placed in the beamline are subject to damage, frequently being destroyed by a single pulse. The ATA is a 50-MeV, 10-kA, 70-ns pulsed electron beam accelerator that generates an extremely harsh environment for diagnostic measurements. International Nuclear Information System (INIS) Optical diagnostics in the advanced test accelerator ( ATA) environment It implements the simplex algorithm to create a fully relaxed solution and… It reads in a configuration file, solves the minimization problem, and produces an output file for postprocessing.
It is a mixed integer linear programming (MILP) solver written in Java. JPLEX, short for Java simPLEX, is an automated test assembly ( ATA) program.
Park, Ryoungsun Kim, Jiseon Dodd, Barbara G. JPLEX: Java Simplex Implementation with Branch-and-Bound Search for Automated Test Assembly In this paper, I compare several approaches to solving the underlying IP problem. A variety of IP solvers are available, ranging in cost from free to hundreds of thousands of dollars. ETS RR-15-05Īt the heart of van der Linden's approach to automated test assembly ( ATA) is a linear programming/integer programming (LP/IP) problem.
