Extended Data Table 2 Measured beam quantities

From: Realization of a multi-turn energy recovery accelerator

  1. The table lists measured bunch length, σt, and momentum spread, σδ, for a beam-current of about 1 nA at different locations. Due to the used measurement methods, the values given are upper estimates. Due to limits in diagnostic options and beam properties, bunch length and momentum spread could not be measured for the decelerated beams.
