A project is currently under way to replace the target assembly of the First Target Station (TS1) in order to secure its continued operation and improve operational flexibility. In addition to a number of other diagnostic tools, a new secondary emission (SEM) grid profile monitor is expected to be located within the helium atmosphere of the new target assembly. To investigate the performance of an out-of-vacuum SEM grid, a prototype monitor was positioned in-air between a beam exit window and a dump. Profile measurements taken with this monitor are presented, including tests at a range of bias voltages with a fast data acquisition system to investigate secondary signal sources.
