abstract = {{The newly constructed superconducting linear accelerator (SRILAC) is now in operation with the aim of discovering new superheavy elements and advancing the production of medical radiation isotopes. Because it is crucial to extend the durability of the expensive Cm target for as long as possible, these experiments require the accelerated V beam to be sufficiently widened. To this end, a helium gas light emission monitor (HeLM) has been introduced to measure the beam profile. Because He gas flows within the target chamber, by capturing the light emitted from He gas with a CCD camera, the beam profile can be obtained nondestructively and continuously. These measurements are handled through programming in LabVIEW, with analyzed data integrated into an EPICS control system. A method to estimate the beam envelope has been recently developed by leveraging the measured quadrupole moments with beam energy position monitors (BEPMs), and incorporating calculations of the transfer matrix. The synergistic use of HeLM and BEPM plays a useful role in accurately controlling the beam size at the Cm target.}},
