The next step is to repeat these experiments with the two TDU scraper elements in place during OP1.2b and compare the neutral flux values to the above results in order to quantify the effect of the scraper element on neutral flux at the divertor for different values of IBS. Along with data from the neutral gas manometers, the impact on pumping efficiency can be measured, which will be one step in determining whether the scraper elements are a viable solution to the problem of heat flux overload caused by bootstrap current evolution during OP2. This work was partially supported by a grant from the 2017-2018 Fulbright U.S. Student Program, administered by the German-American Fulbright Commission. The work was carried out within the framework of the EUROfusion Consortium, with funding from the H2020 Euratom research and training programme 2014-2018 under grant agreement No 633053.
