Cooling Methods and Materials Studies on a MAPS Based Silicon Vertex Tracker
POSTER
Abstract
The silicon vertex tracker (SVT) is a significant component to the ePIC detector for the Electron Ion Collider (EIC) and is currently underway at Lawrence Berkeley National Laboratory. The purpose of this experiment is to explore the mechanical options for the silicon detector responsible for charged particle tracking and collision vertex determination. Additionally, a compact material budget is necessitated in this experiment to prevent particle scattering, which leads to incompetent tracking performance and resolution. Two carbon samples with differing material properties such as specific heat value, thickness, and porosity texture are tested within a reasonable cooling capacity target to determine efficient material candidacy for the SVT. It is important to understand this capacity and avoid exceeding its bounds to ensure that the tracker will not overheat. Thermal measurement can be strongly improved with the development of a new temperature reader built with an Arduino Uno ECB, RTD sensor and coplanar amplifier. Additionally, the glue used to attach the silicon sensor to the mechanical support must be carefully considered and tested to determine its optimal thermal properties. This poster will cover the various approaches to testing these materials with air cooling methods utilizing various airflow values and power densities.
