Current out of the LIS-RFQ

Below is shown plots of typical current outputs from the LIS-RFQ, using the GEL at imput and accelerating the Ta20+ beam from the laser ion source. The measurements were made in August 1999.

Two pulses are shown. The first is measured directly after the RFQ and the second after a bending magnet. Both measurements use a Faraday cup. We see that a very high proportion of unaccelerated beam is found after the RFQ.
