The density of neutral gas may vary the amount of compensation and the resulting ion beam dynamics. We present results for the transport of a 45 keV H- ion beam in the CERN Linac4 together with simulations. The H- beam is provided by a cesiated 2MHz RF ion source with an external solenoid antenna.</div><br><div>Thursday, October 19, 2017<br></div><div>11:00 a.m.<br></div><div>CEBAF Center, Room F113<br></div><br><div>Seminar archives are located here: <a href="https://www.jlab.org/accel/seminars.html" target="_blank">https://www.jlab.org/accel/seminars.html</a><br></div><br><div><div>------<br><b><span style="font-size: small;">Audrey N.
