The comments by Raitses et al. are basically about the comparison between their ion source and the one described in our paper stated in Sec. I. First of all, they do not question our data or the performance of our ion source. After reading their comments carefully, we have the following comments. Raitses et al. may have misread our description. “A cylindrical Hall thruster with a cusp magnetic field for enhanced ionization, especially a low-power Hall thruster, has been investigated by Smirnov et al. The major difference from a conventional end-Hall ion source/thruster is the cylindrical configuration with an enhanced radial component of a cusp-type magnetic field.” In Sec. I of our paper, the above description is also concluded from the following: “A cylindrical Hall thruster CHT , suggested in Ref. 6, is illustrated in Fig. 1 a . The thruster consists of a boron nitride ceramic channel, an annular anode, which serves also as a gas distributor, two electromagnetic coils, and magnetic core. What distinguishes this thruster from conventional annular and end-Hall thrusters is the cylindrical configuration with an enhanced radial component of the cusp-type magnetic field Fig. 1 b .”In our paper, we intended to only briefly introduce other researchers’ works on different Hall ion sources or thrusters, especially about magnetic field distribution. We had no intention to compare the performance of different ion sources, including the CHT and other hall ion sources/thrusters. Therefore, such a detailed comparison is beyond the scope of our paper. In addition, if they want to compare their CHT with the end Hall sources EHS and our cylindrical hall ion source, they should submit a regular paper rather than comment on our paper. It is our belief that comments about a published paper should focus on the data presented, not about one sentence in the introduction that has very little impact on the rest of the paper.
