CEITEC's RapidScan HF-ESR bridge starts operation

With Quasi-Optics from TK and mm-wave sources and detectors from VDI, Petr Neugebauer's multi-frequency
High Field ESR spectrometer is undergoing "first-light" (to use an astronomers term) testing.   With the dry magnet
from Cryogenic Ltd nicely buried in the floor - and  elegant mounting structure and covering from colleagues in
Brno - the Instrument is looking very impressive:

The frequency-independent Quasi-Optical Bridge has an unusual feature of having common path lengths in
both the LO chain and source chain to the primary inductive-mode detector and phase reference - to minimise
the effect of source phase noise on the instrument's' sensitivity.

With the QO Bench exposed, the VDI sources and detectors (black boxes) are connected to TK's high gain corrugated
feed horns, feeding the 125mm cube QO circuit.
