The name SLAC National Accelerator Laboratory pays homage to the legacy of the lab and its connection to Stanford University and the Department of Energy (DOE). Formerly Stanford Linear Accelerator Center, the lab's name was changed in 2008 as SLAC underwent a shift from a focus on particle physics to a broader, multi-program laboratory with research across a range of areas including X-ray science, chemistry, materials science, astrophysics and many others.

The words “National Accelerator Laboratory” signify SLAC’s role as one of 17 DOE national laboratories and one of three DOE national accelerator laboratories (Fermi National Accelerator Laboratory and Thomas Jefferson National Accelerator Facility are the others). The DOE’s national labs are powerhouses of science and technology for the nation and are home to some of the world’s most powerful experiments, fastest supercomputers and preeminent researchers.

• "SLAC National Accelerator Laboratory" should always be spelled out in its entirety on first reference.
• Follow-up references can shorten the name to "SLAC," but the laboratory should never be referred to as "SNAL", "SLACNAL or "SLACLAB."
• As SLAC is no longer an acronym, it should never be spelled out; however, the word "SLAC" should always be represented in upper-case letters.

• The U.S. Department of Energy ("DOE") owns the rights to SLAC logos.
• SLAC, Leland Stanford Jr. University ("Stanford") and the DOE retain the right to revoke the use of the SLAC logos for any reason.
• SLAC logos cannot be used in a manner that would disparage SLAC, Stanford, the DOE or any other government body.
• SLAC logos cannot be used in a manner that has an implied or explicit endorsement of any private company, service or product.
• SLAC logos should only be used in the form and manner as described below and not be altered, cut apart, separated, or otherwise distorted in appearance.

• Do not use any other trademark or service mark in combination with SLAC logos without prior written approval of the DOE.
• The use of the SLAC logos to promote a conference not hosted by SLAC/DOE will require DOE approval. Contact Communications for questions about receiving approval.
• The guidelines on this page do not grant any rights with respect to other names or trademarks associated with Stanford. Those seeking to use Stanford names and marks should refer to the Administrative Guide.

To ensure the integrity and visibility of the SLAC logo, surround it with sufficient clear space — free of text, images and graphics. Whether or not the logo has a descriptor, it must be surrounded on all four sides with the same amount of clear space, proportional to the full cap height of the logo (X). None of the logo versions should appear smaller than 0.35” high. This minimum size ensures that the SLAC logo and partner logos never become too difficult to read.

To receive logo files, please contact Strategic Communications & External Affairs at (650) 926-8703 or communications@slac.stanford.edu.

The logo and word mark can be printed or published in one-color red, one-color black and one-color white. When used on a white background, the one-color red version is preferred. An all-black or all-white version is available for use when the preferred two-color version is not possible or appropriate. Do not create versions of the logo in other colors or proportions.

The red used in the logo has the following color mix:

Pantone® 201 C 
CMYK 0-100-65-34 
Hex: #8C1515 
RGB: 140-21-21

Caution: DO NOT convert between these four color spaces, or else the red will change tone. Use Pantone (spot color only) or CMYK for printed pieces, and RGB and HEX for web and digital colors. When you embed an .eps version of a logo, make sure it is the correct RGB or HEX color value BEFORE saving for web or digital respectively.
