Time used in each activity in the development  of  UST_1    

  

 

Abstract :  Table of the time required to study, design, order, assembly, test, pulses, publish and other from the beginnig of July 2005 until 31 August 2006. It is the period after the first rough ideas for UST_1 until correct  magnetic surfaces were obtained. 

 

 

 

  Notes about the table

 

   Some hours that belong to particular activities are included in the general design and test concept.

Other part of activities are included in not classified issues.

 

 

   The total time in this table  is  2606 hours . It is the time more focussed in the development of UST_1.

 

   Part of the time dedicated to simulation is clearly devoted to the design of the stellarator while other simulations are not necessary and they were run only to learn and better understand stellarators.

 

   Time dedicated to vacuum systems was quite long because all the elements are extremely expensive if not partially or totally built in-site. Moreover  means are poor and it must be obtained the best to be successful.
