It iSjtherefore, important that different types of those large accelerators are dis- 

 tributed over the world and that each region has its specific machine or machines. 

 Hence, it may be tempting to think of an international body that coordinates con- 

 struction projects and distributes "rights'' to build this or that accelerator. Such 

 a solution would perhaps avoid some of the troubles coming from duplication and 

 harmful competition, but it would stifle the initiatives and the forward drive of 

 regional and national groups and may end up in counterproductive squabbles. 



But the world community of High Energy- physicists should be strong enough to 

 solve these problems without "regulative agencies". So far it has gone pretty well, 

 simply by informal and semiformal discussions, by intelligent foresight, sympathy 

 and actual help, technically and financially, for the endeavors of others. It has 

 prevented some unnecessarj- duplications in the past, it has led to a reasonable 

 development where each region contributed in its own way to the progress of the 

 field and had open doors for foreign groups. The higher the cost of a single machine, 

 the more essential it is to avoid duplication and maintain open doors. 



But it is the duty of the community to come to a mutually acceptable solution. 

 It is an issue of scientific responsibility versus scientific greed. But it is also an issue 

 of wise policy towards the governments who pay the bills. We certainly will lose the 

 support that we have received in the past if it appears that different parts of the 

 world community are trjing to outpace each other and are no longer cooperating 

 in the planning and construction of the future accelerators with mutual help and 

 assistance. Even under the best conditions, this support is not assured.
