Beam Energy Station

Developer/Manufacturer: [ELI-NP]

The gamma-ray beam energy spectrum will be determined using a large volume HPGe detector. The HPGe detector will be placed directly in an attenuated beam. A 5-cm thick and 25-cm long NaI anti-Compton shield will be used to reject Compton scattered events in the detector.

Applied for:
spectral measurements (energy & bandwidth)

Beam Profile Station

Developer/Manufacturer: [ELI-NP]

The gamma beam spatial distribution system utilizes a CCD camera to collect the light produced in a scintillator placed in the beam by means of a mirror. The system is designed to be mobile and could be moved to different experimental areas.

Applied for:
spatial measurements (beam diameter, beam divergence, beam pointing stability)

Beam Intensity with Photofission Station

Developer/Manufacturer: [ELI-NP]

The fission chamber will be used for absolute photon flux measurements in the high-energy experimental halls (E7, E8).

Applied for:
power measurements (intensity)
temporal measurement (pulse separation)

Beam Intensity & Polarization with d(g, n) Station

Developer/Manufacturer: [ELI-NP]

For intensity and polarization measurements, a system based on d(γ,n) reaction used at HIGS has been proposed and implemented.
The liquid scintillator detectors were used in the system to detect the outgoing neutrons from the d(γ,n) reaction for gamma beam energies above 4 MeV.
The polarization plane of the polarization system should be frequently rotated by 90 degrees to account for any systematic effects.

Applied for:
spectral measurements (polarization)
power measurements (intensity)

Beam Polarization with NRF Station

Developer/Manufacturer: [ELI-NP]

For intensity and polarization measurements, a system based on d(γ,n) reaction used at HIGS has been proposed.
The liquid scintillator detectors were used in the system to detect the outgoing neutrons from the d(γ,n) reaction for gamma beam energies above 4 MeV.
The polarization measurement will be conducted by using the segmented CLOVER detectors from the ELIADE array.

Applied for:
spectral measurements (polarization)
