Abstract: | The thin n-p+ layer of Si n+-n-p+ wafers composing the light charged particles detectors can be easily damaged by scattered beam projectiles or heavy products of the nuclear reaction in target material. Such damages of the sensitive part of the wafer may in consequence shorten the detector life-time. This could be avoided by protecting the sensitive part of the detector with shielding that stops the heavy projectiles.Due to the compact configuration of the detectors in a small Si-ball counters placing the shielding in front of each wafer could be difficult and therefore a target-shielding assembly is proposed. |
