During the test, only 20% of the detector (length: 80 cm, 18◦ coverage in the azimuthal angle) was instrumented grouping the fibers and steering them to the SiPM boards located on top of the black plastic guides above the shielding. A test with an increase of the readout fraction by...
The 3-dB bandwidth of the integrated variable phase shifter is from dc to 924 MHz, and the optical beam steering range of the three-element array is 0.2°; they are arranged in a triangle. The parameters of the GIF lens are optimized and it is estimated that at the maximum gain ...

LEBT operation proved that the purely electrostatic focusing principle is well suited to inject the ion beam into the RFQ accelerator, including the steering and pre-chopping functions. This paper will discuss the latest design features of the ion source and LEBT, give performance data for the ...
The common examples of these pre-arranged candidates are beam-steering vectors and discrete Fourier transform (DFT) beamformers. Hybrid beamforming algorithms in [26,27,28] are based on the minimum mean squared error (MMSE) criterion for deriving the hybrid beamforming matrices. In contrast to ...
