The figure shows cross-section of one Faraday cup.
The maximum of data rate is 16 sample per second. In case of spectra measuring one step is held during one second and full spectrum takes 16s.
The output range of direct current amplifier is -6.0 - + 6.0 V. The flux can be calculated by :
P = 0.43E+9 1/cm*cm*s/VThe minimal digitased flux is 6.0E+5 1/cm*cm*s
VDP instrument works since August 14, 1995. Two Faraday caps #4 and #6 have problems and are not developed now.
Following pictures demonstrates instrument perfomance:
