Simulating Hexagonal Pixel Sensor Design in Allpix Squared

A hexagonal pixel grid is an alternative pixel sensor geometry that has several potential benefits compared to the rectangular/square pixel sensor geometry, such as improved timing resolution and better efficiency. In order to understand the performance of this design, a completely new detector class has been implemented within the Allpix squared framework. Specifically, the getPixelIndex() function within the new detector class allows the program to successfully extract the index of the pixel based on the position of the hit. Finally, basic simulations involving a hexagonal pixel sensor grid were performed and plots such as hit map, cluster size, cluster charge, and cluster seed charge were extracted.
