148 SCIENTIFIC AND TECHNOLOGICAL COOPERATION 



6. DESY is a German national laboratory that is currently attracting a large number of for- 

 eign, including U.S., scientists to its program; it operates e"'"e" storage rings roughly 

 equivalent to the PEP and SPEAR positron-electron colliders at SLAC. 



7. 1 TeV = 10^^ electron volts. 



8. Cooling here means the compression of phase space, permitting the accumulation and ac- 

 celeration of large amounts of particles like positrons and antiprotons. 



9. Note, however, that the American Institute of Physics (AIP) maintains very useful ar- 

 chives and similarly sponsors historical studies.
