| Energy or Timing Spectroscopy |
Models 142A, 142B, or 142C are
best. Final choice depends on capacitance of detector. Also see
Model 142AH for special applications. |
| General |
Model 142IH, a general-purpose,
economical choice. |

Model VT120 (0 to –5 V output; rise time <1 ns) is the best for
fast PMTs and Electron Multipliers. It can also be used with
photodiodes, Microchannel Plate PMTs, Microchannel Plates, and
Channeltrons.
Model 9301 has ±0.7 V output, rise time <1.5 ns.
Model 9305 has variable gain, ±5 V output drive, dc-coupled (for
high count rates), rise time <3 ns.
Model 9306 (0 to –2 V output; rise time = 350 ps) is best for
microchannel plates and channeltrons. It can also be used with
fast PMTs and photodiodes.
Model 9326 (+0.25 to –1 V output; rise time <1 ns) is ideal for
use with the FASTFLIGHT Digital Signal Averager, due to the 10
kHz low-frequency roll-off. |

Energy Spectroscopy |
Models 142A and 142AH are the ideal choices for Channeltrons,
Micro-channel Plate PMTs, Microchannel Plates, and Photodiodes.
Model 113 is a low-cost solution for PMTs and Scintillation
detectors.
Model 142IH is a general-purpose, economical choice. |
