“…The concept of alternating phase focusing (APF) was originally suggested (to the best of the authors knowledge) by J. Adlam [10] and M. Good [11] in 1953 and independently by I. Fainberg [12] in 1956. The theoretical framework was elaborated in the following years by I. M. Kapchinsky [13]. Yet, the first actual operation of an APF-linac was reported by Y. Iwata et al [14] in 2007 (see Table 2).…”

The recent layout of the Jülich High Brilliance Neutron Source (HBS) driver linac is based on short crossbar H-mode (CH) cavities operated at a fixed synchronous phase. In the last decades the computing power for the development of linacs, available to physicists and engineers, has been increased drastically. This also enabled the accelerator community to finally carry out the required R&D to generate further the idea of drift tube linacs with alternating phase focusing (APF) beam dynamics, originally proposed in the 1950s. This focusing method uses the electric fields in between the drift tubes (i.e., gaps) to provide subsequent transverse and longitudinal focusing to the beam along multiple gaps. The beam focusing properties within each gap are adjusted individually by means of the synchronous phase. As a result of the alternating phase focusing method, these linacs can operate completely without internal magnetic lenses. The R&D-program for the high brilliance neutron source HBS offered the opportunity to investigate the APF concept further in order to open this advanced concept for high duty-factor, high intensity hadron beam acceleration. Besides, a prototype APF-interdigital H-mode (IH)-cavity has been designed and is going to be build and tested in the next future.

“…It appears that the APF method of beam focusing and acceleration was not used extensively because the computational capabilities required to construct this type of cavity were not available. The principle of APF was extensively discussed in literature [13,15,20]. To give a review of the basic concept, consider a standard drift tube linac.…”

The LANSCE accelerator has been in operation for nearly five decades. During this period, it was transformed from a 0.8 MW average proton beam power machine used primarily for the study of meson physics, to a multi-user high-power facility for fundamental research and national security applications, concurrently delivering beams to five distinct experimental areas. Minimization of beam losses in multi-beam application is a key issue for effective operation of accelerator facility. This paper summarizes recent experimental results in understanding and lowering of beam losses in LANSCE linear accelerator and high-energy beam transport lines.
