Hall C Moller Step-By-Step Guide: How to take a Moller Run
Abstract
A step-by-step guide for shift personnel to follow in order to take a Møller run. It is assumed that the polarimeter has already been set up and tuned for the present beam energy by an expert.
HOW TO TAKE A Møller RUN
This document describes the steps to be taken by a Hall-C experimenter performing a Møller beam polarization measurement during NPS running. There is a complimentary procedure which the MCC operators will follow, [1]
- Record Injector Parameters: during some period of "normal" NPS running, record the conditions of the polarized source and the state of the beam to the other halls. This will allow us to verify that we are taking Møller data in a state as close as possible to NPS production data-taking conditions.
