Introduction

Hello, my name is Bryan Orabutt. I am currently a PhD student at Washington University in St. Louis (WUSTL) doing my doctoral studies in computer engineering. I am doing research in the areas of integrated circuit design as applied toward low energy nuclear science.

In my work I often use the Cadence software design tools for integrated circuits, as well as write software in C, Python, and GNU Octave. In my free time I enjoy writing software, particularily for embeded systems, and designing electronics projects. I am also an avid 3D printer user.

Projects

Constant Fraction Discriminator

Integrated Circuit Design

CFD16C is a custom sixteen channel constant fraction discrimiator used to precisely mark the arrival time of input pulses from a scintillator. It is used in experiments involving ionizing radiation, especially where particle identification is important.

Heavy Ion Nuclear Physics

Integrated Circuit Design

HINP16C is a custom peak sensing integrated circuit for use with silicon strip detectors.

A pulse-shape discrimination circuit combining analog and digital paradigms.

Integrated Circuit Design

In nuclear science it is often necessary to classify incident radiation. Traditional methods of doing this involve purely analog or purely digital electronics. This schema borrows techniques from both the analog and digital realms to do pulse-shape discrimination with fewer limitations.
