Technical Committee
The IFES Steering Committee (ISC) established a Technical Committee (TC) to address technical issues of relevance to the IFES community. The committee formed in 2018 and aims to help researchers across the whole community who face common problems in their daily research. The formation of such a committee was requested and backed by members of over 20 laboratories worldwide, to help provide standards and recommendations that will support current and future activities of researchers in the area of field emission and associated research.
We hope that the technical committee provides a source of excellence in research methodologies and guidance to tackle problems which are met by research labs across the world.
Objectives
The TC is to be a “responsive” committee that will consider matters presented to it from a cross-section of the community. Matters that are to be considered shall be those of a technical nature, where a dissemination from the TC can be reasonably expected to provide guidance to the community.
Roles
- To advise the ISC and the IFES community on matters of importance that are technical in nature.
- To communicate best practices and methods for the communication and dissemination of field-emission data, techniques and knowledge.
- To ensure that technical data and recommendations are made available publicly, in perpetuity, with no barriers to access.
If you would like to ask questions, share ideas, raise concerns, or propose suggestions on matters to the TC, we invited you to drop us an e-mail using atomprobe.tc@gmail.com

Updates
Below you can find links to individual resources and activities that have been pushed forward with support of and implemented by members of the community.
HDF File Specification
A file format specification for open information exchange within the field of atom probe and field-emission research, to support developers of software tools
- The specification document for the APT-HDF file format is available here:
- A reference implementation is available here:
https://gitlab.com/atomprobe.tc/apt-hdf5
- Since the release of this specification, there have been several activities to develop an extension of APT-HDF to cover experiment workflows and data analysis in atom probe. An online collaboration webpage has been set up where everybody is invited to comment on these ideas. Annotations can be made by opening the service via clicking the upper right arrow in the screen of your web browser. Alternatively, you can leave your comments via atomprobe.tc@gmail.com. The document to explore and contribute to this work is shared here:

Hashing files for APT
A best practice guide for how hashes can be used as fingerprints of files to document provenance in workflows run on data.
- Background and code to this is available here:
https://gitlab.com/atomprobe.tc/hashing
- An example of how these hashes are used in Oxford is shared here:

Software tools for APT
A list of software tools useful in the field is shared here:
Software library
A Python library that supports developers of software tools and researchers with readers and detailed descriptions of the structure of typical file formats used within the community.
