A stable beam of 500 mA (uniform filling pattern) was delivered for the first time to the beam lines during the last week of the RUN5 of the year 2015: from Tuesday 15 to Monday 21 December…
This value fulfills the specifications in terms of maximum beam current of the Technical Design Report of SOLEIL. This current will be offered to the users on a regular basis starting in 2016.
Storing 500 mA while keeping the same stability and reliability as for the present beam of 450 mA (98.8% over one week) can be done due to the long-term involvement of several groups. Especially the Diagnostics, RF-Linac, Operation, Power Supplies and Pulsed Magnets, Safety, and Accelerator Physics groups have been involved in the specification and the upgrade of equipment. This allows a fine control of the electron charges produced by the injector (Linac and Booster) while preventing the storage ring current from exceeding 505 mA (maximum legal value).
