Setting Up Classifications
Main Classifications
Combining Main Classifications and Sub-classifications

Sub-classifications are used alone or in combination with main classifications.

Scientific Program Administration / Classifications / Sub Classifications

Used together with main classifications, a higher degree of refinement of the subject/topic of the paper presented to the conference is obtained.

Taking the European PAC as an example, there are 8+1 main classifications:

  • 01 Circular Colliders
  • 02 Synchrotron Light Sources and FELs
  • 03 Linear Colliders, Lepton Accelerators, and New Acceleration Techniques
  • 04 Hadron Accelerators
  • 05 Beam Dynamics and Electromagnetic Fields
  • 06 Instrumentation, Controls, Feedback, and Operational Aspects
  • 07 Accelerator Technology Main Systems
  • 08 Applications of Accelerators, Technology Transfer and Relations with Industry


  • Opening, closing, and special presentations reserved only for contributions that cannot be classified otherwise (e.g., opening presentations by politicians, talks on topics outside of the range of the conference programme).

Taking as an example

01 Circular Accelerators

Sub-classifications associated with this main classifications will range from A01 Hadron Accelerators A02 Lepton Accelerators A14 Advanced Concepts


The bonus for using main plus sub-classifications is that it is easier to schedule poster presentations using the SPMS functionality to assign poster programme codes in a more refined manner. For example, the sub-classification Advanced Concepts can be combined with

01 Circular Accelerators, or 02 Synchrotron Light Sources and FELs, or 03 Linear Colliders, Lepton Accelerators, and New Acceleration Techniques


This means that papers on Advanced Concepts (sub-classification A14) can be grouped

  • all together, or *separately, depending on the kind of accelerator, circular, synchrotron light source, or linear collider.
