Information on the former SUPERLUMI at DORIS III and recent activities at other synchrotron radiation sources:
V. Pankratova and A. Kotlovb, Luminescence spectroscopy under synchrotron radiation: From SUPERLUMI to FINESTLUMI, Nuclear Instruments and Methods in Physics Research Section B: Volume 474 (2020), DOI: 10.1016/j.nimb.2020.04.015.
The former SUPERLUMI setup was constructed and developed as a user facility in 1981 at the former synchrotron source DORIS III at DESY (HASYLAB) and it was a flagship experiment for the next three decades. It was most productive endstation among all DORIS III beamlines until 2012, over 1000 publications were published until now.
