Discrete optimization of upgrade scheduling
… infrastructure in some areas, and the cost to upgrade these systems will be significant. The null hypothesis of this study is that there does not exist an approach to upgrades that optimally reduces the financial burden; conversely, the alternative hypothesis is that such an approach does …

CEBAF Upgrade Bunch Length Measurements
<p>Many accelerators use short electron bunches and measuring the bunch length is important for efficient operations. CEBAF needs a suitable bunch length because bunches that are too long will result in beam interruption to the halls due to excessive energy spread and beam loss. In this work, bunch …

Design upgrade for 2.670 compressed air robot
… wheel that is fitted with a one-way bearing. An upgrade to this design was developed that eliminates the linkage system. The robot is propelled forward by one actuator and steered by a servomechanism. A prototype was assembled and used to test the functionality of the final design. The design …

Multicriteria Approximation of Network Design and Network Upgrade Problems
… problem. On the other hand, we use node and edge upgrade models to deal with the fact that in many cases one prefers to change existing networks rather than implementing a newly computed solution from scratch. We investigate the construction of bottleneck constrained forests under a node upgrade …

The SLD vertex detector upgrade (VXD3) and a study of bbg events
This thesis presents a variety of work concerning the design, construction and use of the SLD's vertex detector. SLD's pioneering 120 Mpixel vertex detector, VXD2, was replaced by VXD3, a 307Mpixel CCD vertex detector in January 1996. The motivation for the up-grade detector and its subsquent …

Designing the four rod crab cavity for the high-luminosity LHC upgrade
… for a novel compact crab cavity for the HL-LHC upgrade at CERN, Geneva. The LHC requires 400MHz RF cavities that can provide up to 10MV transverse gradient across two to three cavities with suitably low surface fields for continual operation. As a result, a cavity design was required that would …

Upgrade of the neon soft X-ray spectrometer for Alcator C-Mod
In order to study plasma rotation, temperature, and impurity density, a Neon Soft X-ray Spectrometer (NeSoXs) was installed on the Alcator C-Mod tokamak. This spectrometer used a spherically bent mica crystal as the reflective element in order to separate the spectral and spatial information on the …
