Converter chamber still without moderator and W-converter
Mini-cleanroom for mounting the last meter of the ELBE beamline
ELBE beamline to positron converter
complete positron setup in Cave 111b
Video camera was there during last beam time of neutron target - not a good idea ...
... it got about 5...10 Gy of radiation and the video picture became "colorful"
... however with more light, the camera is still okay.
The Bremsstrahlung-setup at ELBE is used for GiPS (Gamma-induced Positron Spectroscopy)
The gamma beamline
Gamma beamline (black tube)
The two vertical detectors (Ge; 100% efficiency) are used for Coincidence Doppler Broadening Spectroscopy (CDBS)
The gamma beam dump.

Inside the positron converter chamber - top of extraction lense visible
Pt moderator not really in place
electronic rack of GiPS
Control PC for GiPS
In the meantime: Pt moderator at its final position
Now moderator (from the top) and W converter (from the side) are mounted
Be window is mounted and vacuum test was okay - System ready for use
