Description
Part of the ongoing effort to upgrade the intensity of CERN beamlines in the North Experimental Area is examining technologies for their potential use in a radiation-hard transverse beam profile monitors. One such technique is to use a straw detector, potentially operated at a voltage where charge amplification does not occur. We show results from an experiment with a 4.82 mm diameter thin-walled straw detector using a gas mixture of 50/50 $\text{Ar}/\text{CO}_2$ at atmospheric pressure carried out at the High-Radiation to Materials (HiRadMat) facility at CERN. The beam used was a 440 GeV/c bunched proton beam at intensities up to 2.1e11 particles per bunch with a bunch length of 0.37 ns. To our knowledge, a first such measurement of the time-scale of the straw signal saturation is described, made possible by the SPS sending two bunches with a delay of up to 8 $\mu\text{s}$ between them.
