The instrument operates in 19 - 24 GHz microwave reflection mode. 

This instrument consists of a pulsed laser for excitation of free carriers within a sample and microwave probing system, which is equipped with microwave generator, microwave bridge, slit antenna with adjustment components.
Only one sample can be investigated during a single measurement. Laser pulse - 400 ps, wavelength of first harmonic radiation - 1062 nm. Maximum microwave power - 50 mW. 

Application. Monitoring of the radiation dose within environments of large intensity (fluence) particle accelerators.
