Slide #2, Gaussian beam, <img style="vertical-align: middle"
src="cid:part1.551AA7A9.9A57F76C@jlab.org" alt="$\sigma$"> = 5
mm. How are you going to blow the beam up to that size? And how
are you going to measure it? Are you planning to use the Hall-C
raster system? <br>
<br>
Typical beam sizes are 1/4 mm and the wire scanners are designed to
measure beams in the 100s of <img style="vertical-align: middle"
src="cid:part2.041346A9.14FE3A07@jlab.org" alt="$\mu$">ms, not
beams greater than 1 mm. There are viewers available, but they
will not measure beam sigma, just the full-width-at-base.<br>
