Clio is equipped with a double independent ondulator. This characteristic allows to produce two independent pulses at two different wavelength and synchronized at the pico second in the same macro pulse. The wavelength difference is a factor 2. This unique feature allows pump-probe and photon echo experiments.
The helium flow cryostat can be used to cool down samples in a range from 2K to 350K. The the Janis 100ST flow helium cryostat is equipped with the CaF2 or KBr windows.
