ENGINEERING THE RESISTIVE BASES OF THE ELECTROMAGNETIC CALORIMETER IN HALL A AT JEFFERSON LAB

The Super Bigbite Spectrometer (SBS) to be used in Hall A at Jefferson National Accelerator Lab to carry out a number of seminal experiments, such as the measurements of the electric and magnetic form factors of the proton and neutron. The JMU Particle and Nuclear Physics group was tasked with the construction of 1,000 + new bases for the voltage dividers that will be used to power and extract the signal from the Photomultiplier Tubes (PMTs). My task was to design new resistive bases and the layout of their electronic circuit. The challenges and solutions of the design work and electrical measurements of the existing resistive bases will be shown.
