JLC Parameters


				    Phase-I  ->  Energy up

Center-of-mass energy		    0.5      ->  1.5  	TeV
Luminosity 			    5        ->  >10	x10^33/cm^2/s
Total length			   ~25			km
Accelerating gradient		    20~40    ->  120	MV/m
Repetition rate			    150 		Hz
Number of particles/bunch	   ~1        ->  ~3	x10^10)B
Number of bunches/pulse		    50~100		bunch
Total wall-plug power		   <200			MW
Normalized emittance
	Horizontal		    5x10^-6		rad m
	Vertical		    5x10^-8		rad m
Beam spot size at interaction point
	Horizontal		   ~300			nm
	Vertical		   ~3			nm
	bunch length		   ~80			microns
Energy loss due to beamstrahlung   <10			%
The JLC accelerator goes up in energy step by step through enforcements of high-power RF system including klystrons, etc.
