Comment from Alice Bean

[200.202(e), 200.220] To Whom it May Concern: I am a professor of physics doing research in experimental particle physics. Currently I collaborate internationally at CERN as a member of the Compact Muon Solenoid collaboration I am writing in my personal capacity to oppose the proposed revisions to sections 200.202(e) and 200.220 that would restrict international scientific collaboration and isolate American scientists. The Compact Muon Solenoid Collaboration has over 5000 scientists from over 50 countries. We discovered the Higgs boson and are studying how energy is distributed at the smallest scales The U.S. has built several portions of the detector including the over 2 billion pixel central detector set to take data soon and over a third of the collaborators are from the U.S. My research depends on the ability to have personnel travel internationally to help build the detectors. Parts of the detectors are manufactured throughout the world. Our ability to keep at the cutting edge of technology means working with international collaborators Building complex cutting edge detectors to study fundamental physics questions and move technology forward is now a global enterprise. If U.S. collaboration is not allowed, then the U.S. will suffer as the rest of the world moves forward
