In electron storage mode, ASTRID operates as a synchrotron radiation (SR) source. A 100 MeV race track microtron or RTM is used to accumulate up to 250 mA of electrons which are then accelerated to 580 MeV to produce SR from either bending magnets or an undulator magnet. At present five operational beamlines provide SR in the VUV and X-ray spectral regions. Two more are under planning and construction.
