Abstract Transverse-emittance measurements based on the quadrupole-scan technique * ** ***, have been widely used to characterize the beam phase-space parameters in linear accelerators. This paper discusses the implementation of the technique at the Advanced Superconducting Test Accelerator (ASTA) at Fermilab. We plan on deploying a flexible implementation that permits an operator to select the quadrupole associated analysing screen to measure the beam emittance. Our implementation utilizes Python scripts combined with Fermilab’s control system ACNet and ELEGANT quadrupole-scan method at 50 MeV given the range of operating charge (20 pC to 3.2 nC) available at ASTA. Some preliminary measurements will also be presented.
