Antiprotons at CERN's Antiproton Decelerator are created by impinging a proton beam from the Proton Synchrotron on an iridium target.

Notes on verification

Confirmed by multiple independent sources including CERN official pages and peer-reviewed accelerator physics papers, consistent in describing the 26 GeV/c proton beam impinging on an iridium target to produce antiprotons. [tier=gold indep_score=0.89 clusters=5 claim_tier=notable]
