Alpha and gamma spectrometry tracks dedicated to studies on irradiated targets at AIC-144 cyclotron

SILENA Sp.A, Milano, (electronics), IFJ Kraków (germanium detectors), Canberra, Ortec, Tennelec (alpha detectors or spectrometers)


Technical data:

Gamma rays spectrometers equipped with HPGe detectors (home made):
  1. 1. Planar (2000) : S = 12 cm2, h = 8 mm, energy range: 30-500 keV, electronics: Amplifier Silena 7611/L, HV Supply Silena 7716, ADC Silena 7411, equipped with passive standard lead shield, 5 cm thick.
  2. 2. Coaxial (1993), efficiency 7%, energy range 80-2000 keV, electronics: Amplifier Silena 7611/L, HV Supply Silena 7716, ADC Silena 7411. Partial 5 cm thick passive shield, vertical optical bench which allows to measure up to 2 m distance from detector.
Both tracks are connected to Silena MCA build into dedicated PC.
Two alpha spectrometers with Canberra PIPS detectors:
  1. 1. Ortec 576A (two tracks build-in)
  2. 2. Tennelec TC256 (single track)
Both are connected to a single Hetman MCA.
