CERN summer student program report 2019: Simulation with COMSOL, Data Line Separator PCB design, Virtual Control Interface, Simulation on Linux Cluster

This is the report of my projects during the 2019 summer program of CERN. during this period I worked on four projects which were the followings: COMSOL simulation of positron particles, PCB design for compact Rio upgrade, working with HTCondor and using it for COMSOL simulation on Linux clusters, designing a Virtual Instrument interface using LabVIEW to control the positron accumulator.
