Cocktails and other librations-the 88-inch cyclotron radiation effects facility

The 88-inch cyclotron at the E.O. Lawrence Berkeley National Laboratory has unique capabilities of advantage for radiation effects testing (RET) and detector calibrations for space applications. The ability to deliver from protons (low linear energy transfer (LET) and high range) to bismuth (LET=100 MeV/mg/cm²), and most ions in between, makes the cyclotron facility a versatile cosmic ray factory on Earth. In addition, the availability of “cocktail” beams of several ion species allows the luxury of testing parts over a range of LET values with one tuneup, saving time and money
