Tra­di­tion­ally, the process of mea­sur­ing the op­ti­cal pa­ra­me­ters of a beam­line has em­ployed the use of one of two stan­dard meth­ods, namely the three-screen method or a quadru­pole mag­net scan. Both re­quire ei­ther an area of zero dis­per­sion to per­form the mea­sure­ments or knowl­edge of the dis­per­sion func­tion and mo­men­tum spread be­fore­hand in order to pro­vide ac­cu­rate re­sults. There is how­ever a third method that can be used to mea­sure the stan­dard op­ti­cal pa­ra­me­ters, the beam pa­ra­me­ters, the dis­per­sion func­tion, and the mo­men­tum spread si­mul­ta­ne­ously. This method, aptly named the six-screen method, is an ex­ten­sion of the more stan­dard three-screen method. Uti­liz­ing the sim­u­la­tion en­vi­ron­ment of G4beam­line, we sim­u­lated the 8 GeV pro­ton beam in the M4 beam­line and mea­sured the op­ti­cal and beam pa­ra­me­ters using the two stan­dard ap­proaches. Those re­sults were then used as a ref­er­ence to check the vi­a­bil­ity of em­ploy­ing the less stan­dard six-screen method in the M4 line. If shown to be a vi­able op­tion, the six-screen method could be used to re­trieve the dis­per­sion func­tion and mo­men­tum spread of the beam with­out need­ing to change the en­ergy of the beam.
