The vacuum system of MAX IV storage rings : Installation and conditioning

• The installation of the vacuum system of the 3 GeV storage ring was started in November 2014 and finished in May 2015. In August 2015 the commissioning of the storage ring started, the first stored beam has been achieved on the 15th of September 2015. The installation of the vacuum system of the 1.5 GeV storage ring was done from September 2015 and the main part finished in December 2015, the connection to the Linac with the transfer line has been done in August 2016. In September 2016 the commissioning of the 1.5 GeV storage ring started with the first stored beam achieved on the 30th of September 2016. The vacuum system conditioning for the two rings was successful; the average dynamic pressure reduction and the increase in the lifetime with the accumulated beam dose is a demonstration of the good performance of the vacuum system. The installation procedure and the results of the conditioning together with the latest developments are introduced here.
