This article has been retracted at the request of the Editor-in-Chief, in accordance with our policy on publishing ethics.
The article is largely a duplicate publication of a paper already published by the same authors in Physical Review Special Topics -Accelerators and Beams as "High power test of an injector linac for heavy ion cancer therapy facilities" (Phys. Rev. ST Accel. Beams 18, 111002, DOI 10.1103/Phys-RevSTAB.18.111002). The main results and much of the text are identical. The lead author, Dr Liang Lu, submitted this article to Chin. Phys. C while the Phys. Rev. ST Accel. Beams article was still in the peer review process. Each journal then accepted the respective submissions, with the article published in Phys. Rev. ST Accel. Beams before Chin. Phys. C. During submission, authors explicitly declare that the work is original and is not published or under consideration for publication elsewhere. This publication is therefore a serious breach of scientific publishing ethics. The Editorial Board of Chin. Phys. C treats such matters extremely seriously, and hereby retracts this article.
Dr Liang Lu takes full responsibility for this matter, and apologises for his behaviour. The Editors apologise to our readers that this was not detected earlier in the publication process.
