The FASER Collaboration would like to gratefully acknowledge support from the Heising-Simons Foundation (Grant Nos. 2018-1135 and 2019-1179) and the Simons Foundation (Grant No. 623683), as well as the support from the European Organization for Nuclear Research (CERN) that has made it possible to perform the experiment.
We thank the ATLAS SCT Collaboration Board for donating spare SCT modules to FASER, and the LHC Collaboration for the use of their spare ECAL modules.
In addition, we thank the DsTau Collaboration for providing spare emulsion films for the 2018 in situ measurements, as well as the technical and administrative staff members at all FASER institutions for their contributions to the success of the FASER effort.
Preparation studies for FASER were made possible with critical help from the CERN Physics Beyond Colliders study group, and in particular Mike Lamont.
