V. Bonvicini et al., Spectroscopic measurements with a silicon drift detector having a continuous implanted drift cathode-voltage divider, NUCL INST A, 439(2-3), 2000, pp. 471-475
A silicon drift detector (SDD) prototype where the drift electrode also pla
ys the role of a high-voltage divider has been realised and characterised f
or spectroscopic applications at near-room temperatures. Among the advantag
es of this design, is the absence of metal on the sensitive surface which m
akes this detector interesting for soft X-rays. The detector prototype has
a large sensitive area (2 x 130 mm(2)) and the charge is collected by two a
nodes (butterfly-like detector),
The energy resolution of a such a detector has been investigated at near-ro
om temperatures using a commercial, hybrid, low-noise charge-sensitive prea
mplifier. The results obtained for the X-ray lines from Fe-55 and Am-241 ar
e presented. (C) 2000 Elsevier Science B.V. All rights reserved.
