ASTRID is an old, nordic feminine name, but it is now also an acronym for 

Aarhus STorage RIng in Denmark. 

ASTRID was a dual-mode ring which operated between the late 1980's and 2013, storing electrons or ions of either polarity.
Since the construction of ASTRID2, ASTRID operates as the booster ring, accelerating 100 MeV electrons from the race-track microtron to 580 MeV for top-up injections into ASTRID2.

Operational Modes

For many years ASTRID was used in both ion and electron storage modes, with approximately half the year allocated to each mode. With the construction of the Electrostatic Storage Ring for Ions (ELISA) in 1998, and the increasing demand for synchrotron radiation, the ion storage runs were gradually reduced, until finally in 2005 ASTRID operated in ion storage mode for the last time. From 2005 until the commissioning of the new 3rd generation light source ASTRID2, ASTRID operated in electron storage mode throughout the year, with 3 or 4 electron runs, separated by shutdown periods for maintenance and development of the ring.
