Paper Preparation Guidelines

General proceedings information

ICALEPCS has adopted the same standards for electronic publication and has created the Joint Accelerator Conferences Web Site (JACoW ) for publication of their proceedings. General requirements for preparation of papers follow. Detailed formatting requirements are given in the templates themselves.


Authors must use the JACOW templates. The templates contain styles that, when applied, will automatically ensure correct typesetting and layout. In case of difficulties, please consult the JACoW electronic publication help pages.

Authors are strongly advised to use the template that corresponds to the version of software they're using and to not transport the document across different platforms (e.g., MAC <-> PC) or across different versions of WORD on the same platform.

General Layout

The following is a summary of paper requirements. Please see the templates for detailed formatting requirements.

Manuscripts should be prepared for one-sided printing and must meet the following requirements:

  • Paper must be formatted to fit A4 (21.0 x 29.7 cm.) .
  • Text must be single spaced in two columns of 82.5 mm, with 5.3 mm separation.
  • Text and images must fit within the margins specified below:


A4 paper

Top 37 mm 19 mm

Bottom 19 mm 19 mm

Left 20 mm 20 mm

Right 20 mm 26 mm

To be compatible with Adobe Acrobat Distiller, only the following fonts should be used:

  • Times New Roman or Times (Macintosh)
  • Symbol

All text should be in 10 pt font unless otherwise noted.

Length of Contributions

Papers for oral and poster presentation may be up to three pages long. Invited papers may be up to five pages. Papers must conform to these limits.


Acronyms should be defined the first time they appear.

Page Numbers

Papers should not have any page numbers. These will be added by the editing team when the final proceedings are produced.


The title should use 14 pt bold uppercase letters and should be centered on the page.


The names of authors, their organizations/affiliations, and mailing addresses should be in 12 pt uppercase and lowercase letters. When there is more than one author, the submitting author should be first, followed by the coauthors. Coauthors should be grouped by affiliation (to conserve space) and then be listed alphabetically. Authors are kindly reminded that it is their responsibility to check the accuracy of titles and coauthors.

Section Headings

Section headings should use 12 pt bold uppercase letters and be centered in the column. Section headings should not be numbered.

All section headings should appear directly above the text. There should never be a column break between a heading and the text that follows it.

Subsection Headings

Subsection headings should use 12 pt italic letters and be left aligned in the column. As with section headings, subsection headings should not be numbered and there should never be a column break between a heading and the text that follows it.

Figures and Tables

Figures and tables should be placed as close as possible to their first place of mention. Lettering in figures and tables should be large enough to reproduce clearly, using only the approved fonts. Use of nonapproved fonts in figures often leads to problems when the files are processed and could cause loss of information.

All figures and tables should be given sequential numbers (1, 2, 3, etc.) and have a caption placed below the figure or above the table being described. Captions that are one line should be centered; captions of more than one line should be justified.


If a displayed equation needs a number, it should be placed flush with the right margin of the column.


All bibliographical references should be numbered and listed at the end of the paper in a section called "REFERENCES." Corresponding reference numbers in the text should be placed in square brackets.
