In applications where high spatial resolutions in the determination of the position of an interaction are necessary crystal matrices are often used.

One possible way to solve the difficulty is by reading out the row and the column by coupling wavelength shifting fibres to the front and back of the matrix.

Abstract
In applications where high spatial resolutions in the determination of the position of an interaction are necessary crystal matrices are often used. The readout of such matrices can be difficult especially if these have a large number of pixels (>400). One possible way to solve the difficulty is by reading out the row and the column by coupling wavelength shifting fibres to the front and back of the matrix. Measurements have been carried out on the photoelectronyield of one fibrecoupled to a 5×5 YAP:Cematrix so as to prove the principle. The fibre was read out using a single pixel HPD. The results of these measurements will be presented.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
