1Total number of periods is listed. Effective number of periods = N - 2 because end magnets are not of full strength.

2Currently set allowed minimum gap.

3Zero emittance calculated values for a beam energy of 7.0 GeV.

4Calculated for a beam current of 100 mA using peak magnetic fields (not shown).

5 Power and power density calculated from the measured magnetic fields.
