against 20 TeV. However such a Dolicv is not in the interest 

 of U.S. High Energy Physics, and probably also not in the 

 interest of a healthy development of world High Energy Physics. 



In order to understand this situation, it must be realized 

 that, at this moment. Western Europe is overextended in 

 respect to High Energy Physics facilities whereas United States 

 has not enough facilities. In Europe, two relatively large 

 facilities are under construction: "HERA" at Hamburg, an 

 electron-proton collider at a cost of about 1/2 billion 

 dollars, and LEP , at CERN, an electron collider at a cost 

 of almost 1 billion dollars. 



In the United States there is no major facility under 

 construction. The Fermilab accelerator is converted to 

 a proton collider of 1 TeV against 1 TeV,. and SLAC constructs 

 a single path collider for electrons. Both are relatively 

 small projects; furthermore, a similar facilitv to the first 

 one was constructed earlier - albeit at half the energy - at 

 CERN and led to historic discoveries and two Nobel prizes. 



This is why the United States community strongly urges 

 the construction of the Superconducting Super Collider as 

 soon as possible. The present dearth of new facilities is 

 most harmful. There are much too few onportunities for 

 younger people to work; we are about to lose many interested 

 people because of the lack of instruments. Such loss of 

 young people is most detrimental to the future of the field. 



Coming back to the question of advantages of international 

 cost sharing, I must divide the question into two parts. Cost 

 sharing between Western Europe and United States and cost 

 sharing between United States and regions that have no frontline 

 High Energy Physics facilities such as Canada, or no 

 larger facilities such as Janan and perhaps China. I 

 omitted the Soviet Union since, at this Doint in time, a 

 collaboration is not likely. 



I do not see any realistic possibility of cost sharing 

 with Western Europe within the next decade or two. They 

 are overcommitted with their own facilities. Their budgets 

 are already too restricted for the completion and exploitation 

 of HERA and LEP. These two facilities will begin to operate 

 in the late eighties, and will need much financial support 

 to be adequately exploited and upgraded in the nineties. 

 Therefore, it is highly improbable that Western Eurooe could 

 afford to spend significant amounts to help the construction 

 of the Superconducting Super Collider. The same is true in 

 reverse. The United is in such dire need for a new frontier 

 facility that a financial participation in the European LHC 

 project seems rather improbable.
