CRYRING progress: weak beams, rare ions and ordering

Much of the development of the CRYRING facility has been aimed at the production, handling and measurement of weak beams, often of ions that are difficult to produce in the ion sources. Due to the diverse requirements for ions, several different ion source types are in use. To be able to handle and measure the weak beams, the beam diagnostic systems have been improved. The ECR source is in regular use for single pass experiments and will be used for experiments in the storage ring before the summer of 2003. The EBIS source has been renovated and upgraded with a new electron gun and will be back in operation in May 2003.
