SPECTRUM STABILISING PC-MCA
(PHAST2)

Model PHAST2 , a 100MHz Wilkinson type ADC with up to 8K conversion gain, is a PC card with programmable features. It also provides SCA mode MCS operation. The card caters to the specific needs of precision nuclear spectroscopy at low to moderate count rates. 

Salient Feature 

•  Wilkinson type 100MHz ADC with conversion gains of 8K,4K,2K and 1K

•  MCS operation with analog pulse input (SCA mode operation) 

•  ADC differential nonlinearity 2% or less over upper 98% channels 

•  Pile-up rejection input (delayed coincidence/anti-coincidence)  

•  Gedcke-Hale dead time correction or pulser based dead time correction 

•  Spectrum stabilisation with spectral peaks or pulse generator peak

•  On board histogram memory in each card to facilitate independent operation 

•  Simultaneous acquisition of two spectra by logic pulse steering

•  Complete MCA emulation software for simultaneous operation of four cards 

•  Automatic location and area determination of up to 500 peaks 

•  Nonlinear least-square fit of peaks with exponential tailed model  

• Energy , peak shape and efficiency calibration 

• Nuclide identification and activity calculation 

Applications 

• Nuclear Pulse Spectroscopy 
• Pulse Height Analysis
